  • WordPress Conditional: Only show if current page title is equal to post meta

    - by Wade D Ouellet
    Hey, I am calling a bunch of posts under a certain post type in WordPress which works but I am trying to add a conditional that will check first if those post's custom meta field (labeled "disc") is equal to the current post's title. Here is what I have but this conditional does not seem to work: <?php $pages = get_posts('numberposts=9999&post_type=song&post_status=publish&order=ASC&orderby=date'); $i = 1; foreach( $pages as $page ) { $content = $page->post_title; if( empty($content) ) continue; $content = apply_filters('the_content', $content); ?> <?php if(get_post_meta($page->ID, "p30-disc", true)=="the_title()") { ?> <tbody class="vevent"> <?php if ($i%2===0) { ?><tr class="gigpress-row gigpress-alt"> <?php } else { ?><tr class="gigpress-row"><?php } ?> <td><?php echo $page->post_title ?></td> <td><?php echo get_post_meta($page->ID, "p30-length", true); ?></td> <td><a href="http://itunes.com/<?php echo get_post_meta($page->ID, "p30-itunes-song", true); ?>">BUY</a></td> </tr> <tr class="gigpress-info"> <td colspan="3"><?php echo $page->post_content ?></td> </tr> </tbody> <?php $i++; } } ?> When I simply echo "get_post_meta($page-ID, "p30-disc", true)" or "the_title()" it spits out their proper values, which are equal, so obviously something is just wrong with that conditional. Thanks, Wade

  • rails server fails to start with mysql2 using rvm & ruby 1.9.2-p0 on OSX 10.6.5

    - by Scott
    I'm getting the following error when I start rails server: $ rails server /Users/ssmith/.rvm/gems/ruby-1.9.2-p0/gems/mysql2-0.2.6/lib/mysql2.rb:7:in `require': dlopen(/Users/ssmith/.rvm/gems/ruby-1.9.2-p0/gems/mysql2-0.2.6/lib/mysql2/mysql2.bundle, 9): Library not loaded: libmysqlclient.16.dylib (LoadError) Referenced from: /Users/ssmith/.rvm/gems/ruby-1.9.2-p0/gems/mysql2- 0.2.6/lib/mysql2/mysql2.bundle Reason: image not found - /Users/ssmith/.rvm/gems/ruby-1.9.2-p0/gems/mysql2- 0.2.6/lib/mysql2/mysql2.bundle I've installed mysql2 with the following command after the rvm use ruby-1.9.2-p0 command: $ gem install mysql2 -- --with-mysql-dir=/usr/local/mysql --with-mysql-config=/usr/local/mysql/bin/mysql_config Building native extensions.

  • Specification Pattern and Boolean Operator Precedence

    - by Anders Nielsen
    In our project, we have implemented the Specification Pattern with boolean operators (see DDD p 274), like so: public abstract class Rule { public Rule and(Rule rule) { return new AndRule(this, rule); } public Rule or(Rule rule) { return new OrRule(this, rule); } public Rule not() { return new NotRule(this); } public abstract boolean isSatisfied(T obj); } class AndRule extends Rule { private Rule one; private Rule two; AndRule(Rule one, Rule two) { this.one = one; this.two = two; } public boolean isSatisfied(T obj) { return one.isSatisfied(obj) && two.isSatisfied(obj); } } class OrRule extends Rule { private Rule one; private Rule two; OrRule(Rule one, Rule two) { this.one = one; this.two = two; } public boolean isSatisfied(T obj) { return one.isSatisfied(obj) || two.isSatisfied(obj); } } class NotRule extends Rule { private Rule rule; NotRule(Rule obj) { this.rule = obj; } public boolean isSatisfied(T obj) { return !rule.isSatisfied(obj); } } Which permits a nice expressiveness of the rules using method-chaining, but it doesn't support the standard operator precedence rules of which can lead to subtle errors. The following rules are not equivalent: Rule<Car> isNiceCar = isRed.and(isConvertible).or(isFerrari); Rule<Car> isNiceCar2 = isFerrari.or(isRed).and(isConvertible); The rule isNiceCar2 is not satisfied if the car is not a convertible, which can be confusing since if they were booleans isRed && isConvertible || isFerrari would be equivalent to isFerrari || isRed && isConvertible I realize that they would be equivalent if we rewrote isNiceCar2 to be isFerrari.or(isRed.and(isConvertible)), but both are syntactically correct. The best solution we can come up with, is to outlaw the method-chaining, and use constructors instead: OR(isFerrari, AND(isConvertible, isRed)) Does anyone have a better suggestion?

  • jquery Tree Traversal prev() in TD's

    - by Guido Lemmens
    Hello, I'm trying to check/unckeck a selectbox by jquery in a previous TD. I have tried for hours several combination with prev(), parent(), closest(), but still without result... Here is the example code: <table> <tr> <td><input type="checkbox" class="resultcheck"></td> <td><label class="resultchecklabel">Text 1</label></td> </tr> <tr> <td><input type="checkbox" class="resultcheck"></td> <td><label class="resultchecklabel">Text 2</label></td> </tr> </table> <script> $('.resultchecklabel').live('click', function() { if ($(this).prev('td input:checked').val() != null) { $(this).prev('td').prev("input").removeAttr("checked"); } else { $(this).prev('td').prev("input").attr("checked","checked"); } }); </script> Who can help me to solve this question? Many thanks!

  • Multi-level inheritance with Implements on properties in VB.NET vs C#

    - by Ben McCormack
    Let's say I have 2 interfaces defined like so: public interface ISkuItem { public string SKU { get; set; } } public interface ICartItem : ISkuItem { public int Quantity { get; set; } public bool IsDiscountable { get; set; } } When I go to implement the interface in C#, VS produces the following templated code: public class CartItem : ICartItem { #region ICartItem Members public int Quantity { get {...} set {...} } public bool IsDiscountable { get {...} set {...} } #endregion #region ISkuItem Members public string SKU { get {...} set {...} } #endregion } In VB.NET, the same class is built out like so: Public Class CartItem Implements ICartItem Public Property IsDiscountable As Boolean Implements ICartItem.IsDiscountable 'GET SET' End Property Public Property Quantity As Integer Implements ICartItem.Quantity 'GET SET' End Property Public Property SKU As String Implements ISkuItem.SKU 'GET SET' End Property End Class VB.NET explicitly requires you to add Implements IInterfaceName.PropertyName after each property that gets implemented whereas C# simply uses regions to indicate which properties and methods belong to the interface. Interestingly in VB.NET, on the SKU property, I can specify either Implements ISkuItem.SKU or Implements ICartItem.SKU. Although the template built by VS defaults to ISkuItem, I can also specify ICartItem if I want. Oddly, because C# only uses regions to block out inherited properties, it seems that I can't explicitly specify the implementing interface of SKU in C# like I can in VB.NET. My question is: Is there any importance behind being able to specify one interface or another to implement properites in VB.NET, and if so, is there a way to mimic this functionality in C#?

  • LinqToSQL Double Insert issue

    - by Vaccano
    I have a WCF service with an object structure similar to this: public class MyClass { public List<MySubItem> SubItems { get; set; } } public class MySubItem { public List<MySubSubItem> SubSubItems { get; set; } } public class MySubSubItem { public string DataValue { get; set; } } public class MyClassDAL { public void InsertMyClass(MyClass myClass) { ctx.MyClasses.InsertOnSubmit(myClass); ctx.SubmitChanges(); } } Sometimes my client will call in with a MyClass that submits only half of the values that it has in the list SubSubItems. Later it calls the insert with the rest of the list. The problem is that when it does this I get a Primary Key violation. The reason is that it is trying to insert the MySubItem again (because there are more items in the SubSubItems owned by the same MySubItem object). How do I deal with this? Do I just call an Update? Do I have to try to separate them out (updates from inserts)? SQL Server 2008 has a really cool Merge functionally. Is there some way to access that from LinqToSQL?

  • Designer serialization persistence problem in .NET, Windows Forms

    - by Jules
    ETA: I have a similar, smaller, problem here which, I suspect, is related to this problem. I have a class which has a readonly property that holds a collection of components (* not quite, see below). At design time, it's possible to select from the components on the design surface to add to the collection. (Think imagelist, but instead of selecting one, you can select as many as you want.) As a test, I inherit from button and attach my class to it as a property. The persistence problem occurs when I add a component,to the collection, from the design surface after I have added my button to the form. The best way to demonstrate this is to show you the designer generated code: Private Sub InitializeComponent() Dim Provider1 As WindowsApplication1.Provider = New WindowsApplication1.Provider Me.MyComponent2 = New WindowsApplication1.MyComponent Me.MyComponent1 = New WindowsApplication1.MyComponent Me.MyButton1 = New WindowsApplication1.MyButton Me.MyComponent3 = New WindowsApplication1.MyComponent Me.SuspendLayout() ' 'MyButton1 ' Me.MyButton1.ProviderCollection.Add(Me.MyButton1.InternalProvider) Me.MyButton1.ProviderCollection.Add(Me.MyComponent1.Provider) Me.MyButton1.ProviderCollection.Add(Me.MyComponent2.Provider) Me.MyButton1.ProviderCollection.Add(Provider1) //Wrong should be Me.MyComponent3.Provider ' 'Form1 ' Me.Controls.Add(Me.MyButton1) End Sub Friend WithEvents MyComponent1 As WindowsApplication1.MyComponent Friend WithEvents MyComponent2 As WindowsApplication1.MyComponent Friend WithEvents MyButton1 As WindowsApplication1.MyButton Friend WithEvents MyComponent3 As WindowsApplication1.MyComponent End Class As you can see from the code, the collection is not actually a collection of the components, but a collection of a property, 'Provider', from the components. It looks like the problem is occurring because MyComponent3 is created after MyButton. However, in my opinion, this should not make any difference - by the time the serializer comes to add the provider property of MyComponent3, it's already created. Note: You may wonder, why I'm not using AddRange to persist the collection. The reason for this is that if I do, the behaviour changes and none of the items will persist correctly. The designer will create local fields - like Provider1 - for each item in the collection. However if I add another collection to the class which holds the actual MyComponents and persist this, then, somehow, the AddRange method persists correctly in ProviderCollection! There seems to be some kind of quantum double slit experiment going down in code dom. How can I solve this problem?

  • How to serialize a protected property in wcf

    - by Denis Rosca
    Hello, i need some help with wcf serializing. I have two classes Person and Address. The Address class looks like this: public class Adresa : IExtensibleDataObject { private Guid _id; [DataMember] protected virtual Guid Id { get { return _id; } set { _id = value; } } private ExtensionDataObject _extensionData; [DataMember] public virtual ExtensionDataObject ExtensionData { get { return _extensionData; } set { _extensionData = value; } } private string _street; [DataMember] public virtual string Street { get { return this._cUTAM; } set { this._cUTAM = value; } } private string _number; [DataMember] public virtual string Number { get { return this._number; } set { this._number = value; } } private string _postalCode; [DataMember] public virtual string PostalCode { get { return this._postalCode; } set { this._postalCode = value; } } // and some other stuff related to the address } The Person class looks like this: public class PersoanaFizica :IExtensibleDataObject { private Guid _id; [DataMember] protected virtual Guid Id { get { return _id; } set { _id = value; } } private ExtensionDataObject _extensionData; [DataMember] public virtual ExtensionDataObject ExtensionData { get { return _extensionData; } set { _extensionData = value; } } private string _firstName; [DataMember] public virtual string FirstName { get { return this._firstName; } set { this._firstName = value; } } private string _lastName; [DataMember] public virtual string LastName { get { return this._lastName; } set { this._lastName = value; } } } The problem is that when the wcf client the data the Id properties are set to a bunch of zeros ( something like 000000-0000-000000-0000000). Any ideas on why this is happening? Thanks, Denis.

  • SoundManager / Jquery : Get SoundID sID

    - by j-man86
    So I am trying to access a jquery soundmanager variable from one script (wpaudio.js – from the wp-audio plugin) inside of another (init.js – my own javascript). I am creating an alternate pause/play button higher up on the page and need to resume the current soundID, which is contained as part of a class name in the DOM. Here is the code that creates that class name in wpaudio.js: function wpaButtonCheck() { if (!this.playState || this.paused) jQuery('#' + this.sID + '_play').attr('src', wpa_url + '/wpa_play.png'); else jQuery('#' + this.sID + '_play').attr('src', wpa_url + '/wpa_pause.png'); } Here is the output: <img src="http://24.232.185.173/wordpress/wp-content/plugins/wpaudio-mp3-player/wpa_play.png" class="wpa_play" id="wpa0_play"> where wpa0 would be the sID of the sound I need. My current script in init.js is: $('.mixesSidebar #currentSong .playBtn').toggle(function() { soundManager.pauseAll(); $(this).addClass('paused'); }, function() { soundManager.resumeAll(); $(this).removeClass('paused'); }); I need to change resumeAll to "resume(this.sID)", but I need to somehow store the sID onclick and call it in the above function. Alternately, I think a regular expression that could get the class name of the current play button and either parse the string up to the "_play" or use a trim function to get rid of "_play"– but I'm not sure how to do this. Thanks for your help!

  • jqModal dialog - only displaying once

    - by James Inman
    I've got a jqModal dialog with the following code: $(document).ready( function() { $('td.item.active').click( function(e) { $(this).append( '<div class="new">&nbsp;</div>' ); $("#jqModal").jqm({ modal:true, onHide: function(e) { e.w.hide(); // Hide window e.o.remove(); // Remove overlay } }); $('#jqModal').jqmShow(); $('input#add_session').click( function(e) { e.preventDefault(); $('#jqModal').hide(); $('.jqmOverlay').remove(); }); }); }); The HTML used is as follows: <div id="jqModal" class="jqmWindow"> <form action="" method="post"> <ul> <li> <input id="add_session" name="commit" type="submit" value="Add Session" /> <input type="button" name="close" value="Close" id="close" class="jqmClose" /> </li> </ul> </form> </div> When I first click a <td>, the dialog launches without a problem. On the second click (or subsequent), the new class is added to the <div>, but the dialog doesn't launch.

  • Efficient way to handle multiple HTMLPurifier configs.

    - by anomareh
    I'm using HTMLPurifier in a current project and I'm not sure about the most efficient way to go about handling multiple configs. For the most part the only major thing changing is the allowed tags. Currently I have a private method, in each class using HTMLPurifier, that gets called when a config is needed and it creates one from the default. I'm not really happy with this as if 2 classes are using the same config, that's duplicating code, and what if a class needs 2 configs? It just feels messy. The one upside to it, is it's lazy in the sense that it's not creating anything until it's needed. The various classes could be used and never have to purify anything. So I don't want to be creating a bunch of config objects that might not even be used. I just recently found out that you can create a new instance of HTMLPurifier and directly set config options like so: $purifier = new HTMLPurifier(); $purifier->config->set('HTML.Allowed', ''); I'm not sure if that's bad form at all or not, and if it isn't I'm not really sure of a good way to put it to use. My latest idea was to create a config handler class that would just return an HTMLPurifier config for use in subsequent purify calls. At some point it could probably be expanded to allow the setting of configs, but just from the start I figured they'd just be hardcoded and run a method parameter through a switch to grab the requested config. Perhaps I could just send the stored purifier instance as an argument and have the method directly set the config on it like shown above? This to me seems the best of the few ways I thought of, though I'm not sure if such a task warrants me creating a class to handle it, and if so, if I'm handling it in the best way. I'm not too familiar with the inner workings of HTMLPurifier so I'm not sure if there are any better mechanisms in place for handling multiple configs. Thanks for any insight anyone can offer.

  • Hibernate one-to-one mapping

    I have one-to-one hibernate mapping between class Student and class Points: @Entity @Table(name = "Users") public class Student implements IUser { @Id @Column(name = "id") private int id; @Column(name = "name") private String name; @Column(name = "password") private String password; @OneToOne(fetch = FetchType.EAGER, mappedBy = "student") private Points points; @Column(name = "type") private int type = getType(); //gets and sets... @Entity @Table(name = "Points") public class Points { @GenericGenerator(name = "generator", strategy = "foreign", parameters = @Parameter(name = "property", value = "student")) @Id @GeneratedValue(generator = "generator") @Column(name = "id", unique = true, nullable = false) private int Id; @OneToOne @PrimaryKeyJoinColumn private Student student; //gets and sets And then i do: Student student = new Student(); student.setId(1); student.setName("Andrew"); student.setPassword("Password"); Points points = new Points(); points.setPoints(0.99); student.setPoints(points); points.setStudent(student); Session session = HibernateUtil.getSessionFactory().getCurrentSession(); session.beginTransaction(); session.save(student); session.getTransaction().commit(); And hibernate saves student in the table but not saves corresponding points. Is it OK? Should i save points separately?

  • QT: I've inherited from QTreeView. I've inherited from QStandardItem. How do i Style the items?

    - by San Jacinto
    My Google skills must be failing me today. I've inherited from QTreeView to create a TreeView that stores a QStandardItemModel instead of a QAbstractItemModel. I have also inherited from QStandardItem to create a class to store my data in an item as is necessary. I've successfully inserted my derived QStandardItem into my derived QTreeView's QStandardItemModel. Now the trouble is, I can't figure out how to style it. I know that QTreeView has a setStyleSheet(QString) member, but I can't seem to get it working. It may be as simple as I'm not styling the correct attribute. Any pointers would be appreciated. Thanks. For clarity, here are my class defs. class SurveyTreeItem : public QStandardItem { public: SurveyTreeItem(); SurveyTreeItem( const QString & text ); ~SurveyTreeItem(); }; class StandardItemModelTreeView : public QTreeView { public: StandardItemModelTreeView(QWidget* parent = 0); ~StandardItemModelTreeView(); QStandardItemModel* getStandardItemModel(); }; I've tried the following StyleSheets: StandardTreeView::Item { font: 87 12pt 'Arial Black'; } StandardTreeView::QStandardItem { font: 87 12pt 'Arial Black'; } QTreeView::QStandardItem { font: 87 12pt 'Arial Black'; } QTreeView::Item { font: 87 12pt 'Arial Black'; } QTreeView::SurveyTreeItem { font: 87 12pt 'Arial Black'; } StandardTreeView::SurveyTreeItem { font: 87 12pt 'Arial Black'; }

  • TDD test data loading methods

    - by Dave Hanson
    I am a TDD newb and I would like to figure out how to test the following code. I am trying to write my tests first, but I am having trouble for creating a test that touches my DataAccessor. I can't figure out how to fake it. I've done the extend the shipment class and override the Load() method; to continue testing the object. I feel as though I end up unit testing my Mock objects/stubs and not my real objects. I thought in TDD the unit tests were supposed to hit ALL of the methods on the object; however I can never seem to test that Load() code only the overriden Mock Load My tests were write an object that contains a list of orders based off of shipment number. I have an object that loads itself from the database. public class Shipment { //member variables protected List<string> _listOfOrders = new List<string>(); protected string _id = "" //public properties public List<string> ListOrders { get{ return _listOfOrders; } } public Shipment(string id) { _id = id; Load(); } //PROBLEM METHOD // whenever I write code that needs this Shipment object, this method tries // to hit the DB and fubars my tests // the only way to get around is to have all my tests run on a fake Shipment object. protected void Load() { _listOfOrders = DataAccessor.GetOrders(_id); } } I create my fake shipment class to test the rest of the classes methods .I can't ever test the Real load method without having an actual DB connection public class FakeShipment : Shipment { protected new void Load() { _listOfOrders = new List<string>(); } } Any thoughts? Please advise. Dave

  • IValueConverter from string

    - by Aleksandar Toplek
    I have an Enum that needs to be shown in ComboBox. I have managed to get enum values to combobox using ItemsSource and I'm trying to localize them. I thought that that could be done using value converter but as my enum values are already strings compiler throws error that IValueConverter can't take string as input. I'm not aware of any other way to convert them to other string value. Is there some other way to do that (not the localization but conversion)? I'm using this marku extension to get enum values [MarkupExtensionReturnType(typeof (IEnumerable))] public class EnumValuesExtension : MarkupExtension { public EnumValuesExtension() {} public EnumValuesExtension(Type enumType) { this.EnumType = enumType; } [ConstructorArgument("enumType")] public Type EnumType { get; set; } public override object ProvideValue(IServiceProvider serviceProvider) { if (this.EnumType == null) throw new ArgumentException("The enum type is not set"); return Enum.GetValues(this.EnumType); } } and in Window.xaml <Converters:UserTypesToStringConverter x:Key="userTypeToStringConverter" /> .... <ComboBox ItemsSource="{Helpers:EnumValuesExtension Data:UserTypes}" Margin="2" Grid.Row="0" Grid.Column="1" SelectedIndex="0" TabIndex="1" IsTabStop="False"> <ComboBox.ItemTemplate> <DataTemplate DataType="{x:Type Data:UserTypes}"> <Label Content="{Binding Converter=userTypeToStringConverter}" /> </DataTemplate> </ComboBox.ItemTemplate> </ComboBox> And here is converter class, it's just a test class, no localization yet. public class UserTypesToStringConverter : IValueConverter { public object Convert(object value, Type targetType, object parameter, CultureInfo culture) { return (int) ((Data.UserTypes) value) == 0 ?

  • How to use CodeDomSerializer to serialize an object in .Net?

    - by user341127
    I have a class, which is defined as the following: [ToolboxItem(false)] [DesignTimeVisible(false)] [DesignerSerializer("DevExpress.XtraEditors.Design.RepositoryItemCodeDomSerializer, DevExpress.XtraEditors.v10.1.Design", "System.ComponentModel.Design.Serialization.CodeDomSerializer, System.Design")] [Designer("DevExpress.XtraEditors.Design.BaseRepositoryItemDesigner, DevExpress.XtraEditors.v10.1.Design")] [LicenseProvider(typeof(DXEditorLicenseProvider))] public class RepositoryItem : Component, ISupportInitialize, ICustomTypeDescriptor, IImageCollectionHelper {......} I tried the following code to serialize the object of this class. DesignerSerializationManager m = new System.ComponentModel.Design.Serialization.DesignerSerializationManager(); m.CreateSession(); DevExpress.XtraEditors.Design.RepositoryItemCodeDomSerializer s = m.GetSerializer(typeof(RepositoryItem), typeof(DevExpress.XtraEditors.Design.RepositoryItemCodeDomSerializer)) as DevExpress.XtraEditors.Design.RepositoryItemCodeDomSerializer; RepositoryItem i = persistentRepository1.Items[0]; //m.Container.Add(i); s.Serialize(m,i );// An error "Object reference not set to an instance of an object." happended here. For I am not familiar with CodeDom, I have spent one day to get the way out. I guess the above code has some stupid mistakes. Please give me a hand to show how to serialize AND DeSelialize such objects of the class of Repository. BTW, the reason I don't use any other serializer is that I am supposed not to have rights to know the source code of RepositoryItem and others could inherit RepositoryItem at the same time. And actually I have to deal with RepositoryItem and its descendants. Thank you in advance. Ying

  • Ruby: add custom properties to built-in classes

    - by dreftymac
    Question: Using Ruby it is simple to add custom methods to existing classes, but how do you add custom properties? Here is an example of what I am trying to do: myarray = Array.new(); myarray.concat([1,2,3]); myarray._meta_ = Hash.new(); # obviously, this wont work myarray._meta_['createdby'] = 'dreftymac'; myarray._meta_['lastupdate'] = '1993-12-12'; ## desired result puts myarray._meta_['createdby']; #=> 'dreftymac' puts myarray.inspect() #=> [1,2,3] The goal is to construct the class definition in such a way that the stuff that does not work in the example above will work as expected. Update: (clarify question) One aspect that was left out of the original question: it is also a goal to add "default values" that would ordinarily be set-up in the initialize method of the class. Update: (why do this) Normally, it is very simple to just create a custom class that inherits from Array (or whatever built-in class you want to emulate). This question derives from some "testing-only" code and is not an attempt to ignore this generally acceptable approach.

Here is an example of what I am trying to do: myarray = Array.new(); myarray.concat([1,2,3]); myarray._meta_ = Hash.new(); # obviously, this wont work myarray._meta_['createdby'] = 'dreftymac'; myarray._meta_['lastupdate'] = '1993-12-12'; ## desired result puts myarray._meta_['createdby']; #=> 'dreftymac' puts myarray.inspect() #=> [1,2,3] The goal is to construct the class definition in such a way that the stuff that does not work in the example above will work as expected. Update: (clarify question) One aspect that was left out of the original question: it is also a goal to add "default values" that would ordinarily be set-up in the initialize method of the class. Update: (why do this) Normally, it is very simple to just create a custom class that inherits from Array (or whatever built-in class you want to emulate). This question derives from some "testing-only" code and is not an attempt to ignore this generally acceptable approach.

  • Eclipse says I don't implement Enumeration, but I do

    - by Harm De Weirdt
    Goodmorning everybody, I'm having a little problem with a project for school. We are told to make an Iterator that implements Enumeration over a Hashmap. So i made this Enumeration: public Enumeration<Object> getEnumeration() { return new Enumeration<Object>() { private int itemsDone = 0; Collection<Long> keysCollection = getContent().keySet(); Long [] keys = keysCollection.toArray(new Long[keysCollection.size()]); @Override public boolean hasMoreElements() { if(itemsDone < getContent().size() +1 ) { return true; }else { return false; } } @Override public Object nextElement() { return getContent().get(keys[itemsDone++]); } }; } This goes in my Backpack class public class Backpack extends Item implements Carrier, Enumeration<Object>{ The hashmap is returned by getContent(). The problem now is that eclipse keeps telling me I havent implemented the methods from Enumeration. If I use the quick fix it just adds the hasMoreElements() and nextElement() dummy methods in my class. Somehow it doesn't see these methods in the inner class.. Can anyone help me please? Any help is appreciated.

  • Problem calling Java from PHP script

    - by Jack
    I am working on windows. I am running PHP (5.1.3) scripts on Tomcat using PHP/Java bridge. Here is my simple code //test.php <?php require_once("java\Java.inc"); $systemInfo = new Java("Test"); print $systemInfo->foo(); ?> Test.class is in the same folder as test.php. But the php file is not able to locate the test class and I get the following error - Fatal error: Uncaught [[o:Exception]:"java.lang.Exception: CreateInstance failed: new Test. If I use a standard class like below. It works - <?php require_once("java\Java.inc"); $systemInfo = new Java("java.lang.System"); print "Total seconds since January 1, 1970: ".$systemInfo->currentTimeMillis(); ?> What should I do? 1)Should I copy my class to the standard location where all Java classes are kept. (What is this location?) 2) Do some changes in the php.ini file

  • ActiveRecord table inheritence using set_table_names

    - by Jinyoung Kim
    Hi, I'm using ActiveRecord in Ruby on Rails. I have a table named documents(Document class) and I want to have another table data_documents(DataDocument) class which is effectively the same except for having different table name. In other words, I want two tables with the same behavior except for table name. class DataDocument < Document #set_table_name "data_documents" self.table_name = "data_documents" end My solution was to use class inheritance as above, yet this resulted in inconsistent SQL statement for create operation where there are both 'documents' table and 'data_documents' table. Can you figure out why and how I can make it work? >> DataDocument.create(:did=>"dd") ActiveRecord::StatementInvalid: Mysql::Error: Unknown column 'data_documents.did' in 'where clause': SELECT `documents`.id FROM `documents` WHERE (`data_documents`.`did` = BINARY 'dd') LIMIT 1 from /Users/lifidea/.gem/ruby/1.8/gems/activerecord-2.3.2/lib/active_record/connection_adapters/abstract_adapter.rb:212:in `log' from /Users/lifidea/.gem/ruby/1.8/gems/activerecord-2.3.2/lib/active_record/connection_adapters/mysql_adapter.rb:320:in `execute' from /Users/lifidea/.gem/ruby/1.8/gems/activerecord-2.3.2/lib/active_record/connection_adapters/mysql_adapter.rb:595:in `select' from /Users/lifidea/.gem/ruby/1.8/gems/activerecord-2.3.2/lib/active_record/connection_adapters/abstract/database_statements.rb:7:in `select_all_without_query_cache' from /Users/lifidea/.gem/ruby/1.8/gems/activerecord-2.3.2/lib/active_record/connection_adapters/abstract/query_cache.rb:62:in `select_all'

  • Declaring functors for comparison ??

    - by Mr.Gando
    Hello, I have seen other people questions but found none that applied to what I'm trying to achieve here. I'm trying to sort Entities via my EntityManager class using std::sort and a std::vector<Entity *> /*Entity.h*/ class Entity { public: float x,y; }; struct compareByX{ bool operator()(const GameEntity &a, const GameEntity &b) { return (a.x < b.x); } }; /*Class EntityManager that uses Entitiy*/ typedef std::vector<Entity *> ENTITY_VECTOR; //Entity reference vector class EntityManager: public Entity { private: ENTITY_VECTOR managedEntities; public: void sortEntitiesX(); }; void EntityManager::sortEntitiesX() { /*perform sorting of the entitiesList by their X value*/ compareByX comparer; std::sort(entityList.begin(), entityList.end(), comparer); } I'm getting a dozen of errors like : error: no match for call to '(compareByX) (GameEntity* const&, GameEntity* const&)' : note: candidates are: bool compareByX::operator()(const GameEntity&, const GameEntity&) I'm not sure but ENTITY_VECTOR is std::vector<Entity *> , and I don't know if that could be the problem when using the compareByX functor ? I'm pretty new to C++, so any kind of help is welcome.

  • why assign null value or another default value firstly?

    - by Phsika
    i try to generate some codes. i face to face delegates. Everythings is ok.(Look below) But appearing a warning: you shold assing value why? but second code below is ok. namespace Delegates { class Program { static void Main(string[] args) { HesapMak hesapla = new HesapMak(); hesapla.Calculator = new HesapMak.Hesap(hesapla.Sum); double sonuc = hesapla.Calculator(34, 2); Console.WriteLine("Toplama Sonucu:{0}",sonuc.ToString()); Console.ReadKey(); } } class HesapMak { public double Sum(double s1, double s2) { return s1 + s2; } public double Cikarma(double s1, double s2) { return s1 - s2; } public double Multiply(double s1, double s2) { return s1 * s2; } public double Divide(double s1, double s2) { return s1 / s2; } public delegate double Hesap(double s1, double s2); public Hesap Calculator; ----&#60; they want me assingn value } } namespace Delegates { class Program { static void Main(string[] args) { HesapMak hesapla = new HesapMak(); hesapla.Calculator = new HesapMak.Hesap(hesapla.Sum); double sonuc = hesapla.Calculator(34, 2); Console.WriteLine("Toplama Sonucu:{0}",sonuc.ToString()); Console.ReadKey(); } } class HesapMak { public double Sum(double s1, double s2) { return s1 + s2; } public double Cikarma(double s1, double s2) { return s1 - s2; } public double Multiply(double s1, double s2) { return s1 * s2; } public double Divide(double s1, double s2) { return s1 / s2; } public delegate double Hesap(double s1, double s2); public Hesap Calculator=null; } }
