  • mockito ArrayList<String> problem...

    - by Sardathrion
    I have a method that I am trying to unit test. This method takes a parameter as an ArrayList and does things with it. The mock I am trying to define is: ArrayList<String> mocked = mock(ArrayList.class); which gives a [unchecked] unchecked conversion" warning. ArrayList<String> mocked = mock(ArrayList<String>.class); gives me an error. Anyone care to enlighten me as to what I am doing wrong?

  • adding custom fields dynamically to a model

    - by pankajbhageria
    I have a model called List which has many records: class List has_many :records end class Record end The table Record has 2 permanent fields: name, email. Besides these 2 fields, for each List a Record can have 'n' custom fields. For example: for list1 I add address(text), dob(date) as custom fields. Then while adding records to list one, each record can have values for address and dob. Is there any ActiveRecord plugin which provides this type of functionality? Or else could you share your thoughts on how to model this? Thanks in advance, Pankaj

  • Modularity Java: top level vs. nested classes

    - by an00b
    The Java tutorials that I read, like to use nested classes to demonstrate a concept, a feature or use. This led me to initially implement a sample project I created just like that: Lots of nested classes in the main activity class. It works, but now I got a monstrous monolithic .java file. I find it somewhat inconvenient and I now intend to break to multiple .java files/classes. It occurred to me, however, that sometimes there may be reasons not to take classes out of their enclosing class. If so, what are good reasons to keep a module large, considering modularity and ease of maintenance?

  • Ontology and same individuals

    - by blueomega
    I am having a problem with "same individuals property" in protege, when i run a reasoner (pellet 1.5 or fact++) Lets take ontology example thing has class sons A and B, A has sons C and D. B, C and D have individuals of the same class. Cant i say a individual C is "same individual" as individual B, and then add also individual D is "same individual" as individual B. Wich is true, they have diferent names, but they are same individual.. Why does it only work when i set individual B has "same individual" of type C or D? The protege error is "InconsistentOntologyException:Fact++.Kernel: inconsistent Ontology" and pellet says ontology is inconsistent. EDIT: Seems its a more deep rooted problem, this example works :(, gonna keep checking. EDIT2: After some more experimenting, seems its a conflict with DataType properties. They all share a DataType properties with same name. In the example domain of property would be A and range string. Any idea how to solve?

Any suggestion..

  • Authorization in a more purely OOP style...

    - by noblethrasher
    I've never seen this done but I had an idea of doing authorization in a more purely OO way. For each method that requires authorization we associate a delegate. During initialization of the class we wire up the delegates so that they point to the appropriate method (based on the user's rights). For example: class User { private deleteMemberDelegate deleteMember; public StatusMessage DeleteMember(Member member) { if(deleteMember != null) { deleteMember(member); } } //other methods defined similarly... User(string name, string password) //cstor. { //wire up delegates based on user's rights. //Thus we handle authentication and authorization in the same method. } } This way the client code never has to explictly check whether or not a user is in a role, it just calls the method. Of course each method should return a status message so that we know if and why it failed. Thoughts?

  • Automatic database generation / migration with perl

    - by pistacchio
    Hi, In Ror or Django or web2py you can "describe" a database (as a set of classes that remaps to tables) and the framework (having being provided with a connection string to the desired database) generates the tables, fields, relations and in the case of RoR and web2py it also keeps it up-to-date (eg, removing a class drops the table, adding a property to the class triggers an "alter table add" etc). Is there any perl module that does the same? Eg, it takes the YAML / XML / JSON description of a database as input and modifies / generates the database accordingly? Thanks in advance.

  • How should I implement items that are normalized in the Database, in Object Oriented Design?

    - by Jonas
    How should I implement items that are normalized in the Database, in Object Oriented classes? In the database I have a big table of items and a smaller of groups. Each item belong to one group. This is how my database design look like: +----------------------------------------+ | Inventory | +----+------+-------+----------+---------+ | Id | Name | Price | Quantity | GroupId | +----+------+-------+----------+---------+ | 43 | Box | 34.00 | 456 | 4 | | 56 | Ball | 56.50 | 3 | 6 | | 66 | Tin | 23.00 | 14 | 4 | +----+------+-------+----------+---------+ Totally 3000 lines +----------------------+ | Groups | +---------+------+-----+ | GroupId | Name | VAT | +---------+------+-----+ | 4 | Mini | 0.2 | | 6 | Big | 0.3 | +---------+------+-----+ Totally 10 lines I will use the OOP classes in a GUI, where the user can edit Items and Groups in the inventory. It should also be easy to do calculations with a bunch of items. The group information like VAT are needed for the calculations. I will write an Item class, but do I need a Group class? and if I need it, should I keep them in a global location or how do I access it when I need it for Item-calculations? Is there any design pattern for this case?

    - by vivmal
    Hi All, I am working on struts2. I have an interceptor that executes before my action claas. Now when I submit on a jsp page control goes to interceptor and after some processing there the control goes to action class. This complete flow is running well. But I found two things – 1) Control does not go to action-validation.xml before going to action class. 2) Its not getting the values of textfield or etc that uses has entered into jsp page before submitting. Can anyone tell me how to find solution for these two points. Thanks in advance.

  • Android GridView - How to change a bitmap dynamically?

    - by Alborz
    Hello I have a gridView which I use to show some pictures on (small thumb of diffrent levels). When the user finishes one level, I would like to change the thumb for that level. (Somehow show that it has been completed). I created two thumbs for each level. One is the original and one that shows that the level is completed. But how can i change the source of the images? The code which I use to draw the images looks like this. The main activity: /** Called when the activity is first created. */ public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.maps); GridView gridview = (GridView) findViewById(R.id.gridview); gridview.setAdapter(new ImageAdapter(this)); gridview.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View v, int position, long id) { //Open the map which was clicked on, if there is one if(position+1 > 1){ Toast.makeText(maps.this, "Level " + (position+1) + " is not yet available!", Toast.LENGTH_SHORT).show(); }else{ Toast.makeText(maps.this, "Opening Level " + (position+1), Toast.LENGTH_SHORT).show(); Intent myIntent = new Intent(v.getContext(), Tutorial2D.class); startActivity(myIntent); } } }); } The ImageAdapter Class: public class ImageAdapter extends BaseAdapter { private Context mContext; public ImageAdapter(Context c) { mContext = c; } public int getCount() { return mThumbIds.length; } public Object getItem(int position) { return null; } public long getItemId(int position) { return 0; } // create a new ImageView for each item referenced by the Adapter public View getView(int position, View convertView, ViewGroup parent) { ImageView imageView; if (convertView == null) { // if it's not recycled, initialize some attributes imageView = new ImageView(mContext); imageView.setLayoutParams(new GridView.LayoutParams(85, 85)); imageView.setScaleType(ImageView.ScaleType.CENTER_CROP); imageView.setPadding(8, 8, 8, 8); } else { imageView = (ImageView) convertView; } //Changing imageView.setImageResource(mThumbIds[position]); return imageView; } // references to our images private Integer[] mThumbIds = { R.drawable.map1, R.drawable.map2, R.drawable.map3, R.drawable.map4, R.drawable.map5, R.drawable.map6, R.drawable.map7, R.drawable.map8, R.drawable.map9, R.drawable.map10, R.drawable.map11, R.drawable.map12, R.drawable.map13, R.drawable.map14, R.drawable.map15, R.drawable.map16, R.drawable.map17, R.drawable.map18, R.drawable.map19 }; }

  • WCF Service with callbacks coming from background thread?

    - by Mark Struzinski
    Here is my situation. I have written a WCF service which calls into one of our vendor's code bases to perform operations, such as Login, Logout, etc. A requirement of this operation is that we have a background thread to receive events as a result of that action. For example, the Login action is sent on the main thread. Then, several events are received back from the vendor service as a result of the login. There can be 1, 2, or several events received. The background thread, which runs on a timer, receives these events and fires an event in the wcf service to notify that a new event has arrived. I have implemented the WCF service in Duplex mode, and planned to use callbacks to notify the UI that events have arrived. Here is my question: How do I send new events from the background thread to the thread which is executing the service? Right now, when I call OperationContext.Current.GetCallbackChannel<IMyCallback>(), the OperationContext is null. Is there a standard pattern to get around this? I am using PerSession as my SessionMode on the ServiceContract. UPDATE: I thought I'd make my exact scenario clearer by demonstrating how I'm receiving events from the vendor code. My library receives each event, determines what the event is, and fires off an event for that particular occurrence. I have another project which is a class library specifically for connecting to the vendor service. I'll post the entire implementation of the service to give a clearer picture: [ServiceBehavior( InstanceContextMode = InstanceContextMode.PerSession )] public class VendorServer:IVendorServer { private IVendorService _vendorService; // This is the reference to my class library public VendorServer() { _vendorServer = new VendorServer(); _vendorServer.AgentManager.AgentLoggedIn += AgentManager_AgentLoggedIn; // This is the eventhandler for the event which arrives from a background thread } public void Login(string userName, string password, string stationId) { _vendorService.Login(userName, password, stationId); // This is a direct call from the main thread to the vendor service to log in } private void AgentManager_AgentLoggedIn(object sender, EventArgs e) { var agentEvent = new AgentEvent { AgentEventType = AgentEventType.Login, EventArgs = e }; } } The AgentEvent object contains the callback as one of its properties, and I was thinking I'd perform the callback like this: agentEvent.Callback = OperationContext.Current.GetCallbackChannel<ICallback>(); How would I pass the OperationContext.Current instance from the main thread into the background thread?

What is the actual way to complete the above three tasks? ( Tasks 1 ,2 ,3 are explained above). Thanks to all.

  • Data bind enum properties to grid and display description

    - by TrueWill
    This is a similar question to How to bind a custom Enum description to a DataGrid, but in my case I have multiple properties. public enum ExpectationResult { [Description("-")] NoExpectation, [Description("Passed")] Pass, [Description("FAILED")] Fail } public class TestResult { public string TestDescription { get; set; } public ExpectationResult RequiredExpectationResult { get; set; } public ExpectationResult NonRequiredExpectationResult { get; set; } } I'm binding a BindingList<TestResult> to a WinForms DataGridView (actually a DevExpress.XtraGrid.GridControl, but a generic solution would be more widely applicable). I want the descriptions to appear rather than the enum names. How can I accomplish this? (There are no constraints on the class/enum/attributes; I can change them at will.)

  • How to share a variable between two classes?

    - by Altefquatre
    How would you share the same object between two other objects? For instance, I'd like something in that flavor: class A { private string foo_; // It could be any other class/struct too (Vector3, Matrix...) public A (string shared) { this.foo_ = shared; } public void Bar() { this.foo_ = "changed"; } } ... // inside main string str = "test"; A a = new A(str); Console.WriteLine(str); // "test" a.Bar(); Console.WriteLine(str); // I get "test" instead of "changed"... :( I read there is some ref/out stuff, but I couldn't get what I'm asking here. I could only apply some changes in the methods scope where I was using ref/out arguments... I also read we could use pointers, but is there no other way to do it?

  • Nhibernate ValueType Collection as delimited string in DB

    - by JWendel
    Hi I have a legacy db that I am mapping with Nhibernate. And in several locations a list och strigs or domain objects are mapped as a delimited string in the database. Either 'string|string|string' in the value type cases and like 'domainID|domainID|domainID' in the references type cases. I know I can create a dummy property on the class and map to that fields but I would like to do it in a more clean way, like when mapping Enums as their string representation with the EnumStringType class. Is a IUserType the way to go here? Thanks in advance /Johan

  • SQLAlchemy declarative syntax with autoload in Pylons

    - by Juliusz Gonera
    I would like to use autoload to use an existings database. I know how to do it without declarative syntax (model/_init_.py): def init_model(engine): """Call me before using any of the tables or classes in the model""" t_events = Table('events', Base.metadata, schema='events', autoload=True, autoload_with=engine) orm.mapper(Event, t_events) Session.configure(bind=engine) class Event(object): pass This works fine, but I would like to use declarative syntax: class Event(Base): __tablename__ = 'events' __table_args__ = {'schema': 'events', 'autoload': True} Unfortunately, this way I get: sqlalchemy.exc.UnboundExecutionError: No engine is bound to this Table's MetaData. Pass an engine to the Table via autoload_with=<someengine>, or associate the MetaData with an engine via metadata.bind=<someengine> The problem here is that I don't know where to get the engine from (to use it in autoload_with) at the stage of importing the model (it's available in init_model()). I tried adding meta.Base.metadata.bind(engine) to environment.py but it doesn't work. Anyone has found some elegant solution?

  • Automapping to EntityKeys in Entity Framework

    - by CodeGrue
    Does anyone have a technique to automap (using Automapper) references to child entities. So say I have a ViewModel: class AddressModel { int Id; string Street; StateModel State; } class StateModel { int Id; string Name; } And I pass this into a repository to map to equivalent entities in Entity Framework. When Automapping, I want it to automap AddressModel.State.ID to the EntityKey of AddressEntity.StateReference. So hand crafted code would look like this: addressEntity.Id = AddressModel.Id; addressEntity.Street = AddressModel.Street addressEntity.StateReference.EntityKey = new EntityKey("MyDB.States", "Id", AddressModel.State.Id); Obviously, when automapper tries to assign an Address.State.Id to the equivalent in EF, an exception is thrown.

  • Thread testing for time

    - by DanielFH
    Hi there :) I'm making a thread for my application that's going to do an exit operation at a given time (only hours and minutes, day/month doesn't matter). Is this the right way to do it, and also the right way to test for time? I'm testing for a 24 hour clock by the way, not AM / PM. I'm then in another class going to call this something like new Thread(new ExitThread()).start(); public class ExitThread implements Runnable { @Override public void run() { Date date = new Date(System.currentTimeMillis()); String time = new SimpleDateFormat("HHmmss").format(date); int currentTime = Integer.parseInt(time); int exitTime = 233000; while(true) { try { Thread.sleep(10000); } catch (InterruptedException e) { e.printStackTrace(); } if(currentTime >= exitTime ) { // do exit operation here } } } Thanks. //D
