  • Disadvantage of OOP?

    - by Bragaadeesh
    Typically i dont want to know the specifics of the cons of OOPs, but it felt kind of weird when I had an argument at an interview I attended recently. The question that was posted to me was to tell me one disadvantage of OOP (Object Oriented Programming). At that time, I felt OOP to be the most matured level of programming after the procedural/functional models. So I replied to him that I dont see any negatives at all. But the interviewer said there are few and I asked him to list one if he does not mind. He gave an example that I cant digest well, he said that OOP pattern does not strictly implement inheritance rules and cited the satellite/rocket example where the body parts will disintegrate periodically to remove weight during rocket launch and said that inheritance does not support this. His example kind of felt very weird to me the reason being the application of inheritance to this example. Then I left the example aside and I had this doubt - Can we unplug class hierarchies in such a manner (I am kind of confident in Java its not possible) in an ideal Object Oriented Design?

  • Templates and inheritance

    - by mariusz
    Hello, I have a big problem. I use additional controls for Wpf. One of them is Telerik RadWindow This control is already templated. Now I want to create custom Window with will inherit from RadWindow, and make custom template, eg. One base window will contains grid and two buttons, second base window will contain two grids (master - detail). The problem is that templates do not support inheritance. Perhaps is another way to template only the content of Winodow? My code, that doesn't work (empty window appears, so template doesn't apply) <Style TargetType="{x:Type local:TBaseRjWindow}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type local:TBaseRjContent}"> <Border Background="{TemplateBinding Background}" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}"> <Grid Name="mGrid"> <Grid.ColumnDefinitions> <ColumnDefinition /> </Grid.ColumnDefinitions> <Grid.RowDefinitions> <RowDefinition /> <RowDefinition MaxHeight="40" MinHeight="30" /> <RowDefinition MaxHeight="40" MinHeight="30" /> <RowDefinition Height="Auto" /> <RowDefinition MaxHeight="40" MinHeight="30" /> </Grid.RowDefinitions> <telerik:RadGridView Margin="10,10,10,10" Name="grid" Grid.Row="0" Grid.Column="0" VerticalAlignment="Stretch" HorizontalAlignment="Stretch" ScrollMode="Deferred" AutoGenerateColumns="False" Width="Auto" > </telerik:RadGridView> <telerik:RadDataPager Grid.Row="1" Grid.Column="0" x:Name="radDataPager" PageSize="50" AutoEllipsisMode="None" DisplayMode="First, Previous, Next, Text" Margin="10,0,10,0"/> <StackPanel Grid.Row="1" Grid.Column="0" Margin="5 5 5 5" HorizontalAlignment="Left" Orientation="Horizontal" Height="20" Width="Auto" VerticalAlignment="Center" > <telerik:RadButton x:Name="btAdd" Margin="5 0 5 0" Content="Dodaj" /> <telerik:RadButton x:Name="btEdit" Margin="5 0 5 0" Content="Edytuj" /> <telerik:RadButton x:Name="btDelete" Margin="5 0 5 0" Content="Usun" /> </StackPanel> <StackPanel Name="addFields" Background="LightGray" Visibility="Collapsed" VerticalAlignment="Top" Grid.Row="2" Grid.Column="0" Width="Auto" Height="Auto" Orientation="Horizontal"> <GroupBox Header="Szczegoly" Margin="2 2 2 2" > <Grid VerticalAlignment="Top" DataContext="{Binding SelectedItem, ElementName=grid}" Name="_gAddFields" Margin="0 0 0 0" Width="Auto" Height="Auto" > </Grid> </GroupBox> </StackPanel> <StackPanel Grid.Row="3" Grid.Column="0" Margin="5 5 5 5" HorizontalAlignment="Right" Orientation="Horizontal" Height="25" Width="Auto" VerticalAlignment="Center" > <telerik:RadButton x:Name="btSave" IsDefault="True" Width="60" Margin="5 0 5 0" Content="Zapisz" /> <telerik:RadButton x:Name="btOK" IsDefault="True" Width="60" Margin="5 0 5 0" Content="Akceptuj" /> <telerik:RadButton x:Name="btCancel" IsCancel="True" Width="60" Margin="5 0 5 0" Content="Anuluj" /> </StackPanel> </Grid> </Border> </ControlTemplate> </Setter.Value> </Setter> </Style> Please help

  • Multiple Inheritence with same Base Classes in Python

    - by Jordan Reiter
    I'm trying to wrap my head around multiple inheritance in python. Suppose I have the following base class: class Structure(object): def build(self, *args): print "I am building a structure!" self.components = args And let's say I have two classes that inherit from it: class House(Structure): def build(self, *args): print "I am building a house!" super(House, self).build(*args) class School(Structure): def build(self, type="Elementary", *args): print "I am building a school!" super(School, self).build(*args) Finally, a create a class that uses multiple inheritance: class SchoolHouse(School, House): def build(self, *args): print "I am building a schoolhouse!" super(School, self).build(*args) Then, I create a SchoolHouse object and run build on it: >>> sh = SchoolHouse() >>> sh.build("roof", "walls") I am building a schoolhouse! I am building a house! I am building a structure! So I'm wondering -- what happened to the School class? Is there any way to get Python to run both somehow? I'm wondering specifically because there are a fair number of Django packages out there that provide custom Managers for models. But there doesn't appear to be a way to combine them without writing one or the other of the Managers as inheriting from the other one. It'd be nice to just import both and use both somehow, but looks like it can't be done? Also I guess it'd just help to be pointed to a good primer on multiple inheritance in Python. I have done some work with Mixins before and really enjoy using them. I guess I just wonder if there is any elegant way to combine functionality from two different classes when they inherit from the same base class.

  • XSL testing empty strings with <xsl:if> and sorting

    - by AdRock
    I am having trouble with a template that has to check 3 different nodes and if they are not empty, print the data I am using for each node then doing the output but it is not printing anything. It is like the test returns zero. I have selected the parent node of each node i want to check the length on as the template match but it still doesn't work. Another thing, how do i sort the list using . I tried using this but i get an error about loading the stylesheet. If i take out the sort it works <xsl:template match="folktask/member"> <xsl:if test="user/account/userlevel='3'"> <xsl:sort select="festival/event/datefrom"/> <div class="userdiv"> <xsl:apply-templates select="user"/> <xsl:apply-templates select="festival"/> </div> </xsl:if> </xsl:template> <xsl:template match="festival"> <xsl:apply-templates select="contact"/> </xsl:template> This should hopefully finish all my stylesheets. This is the template I am calling <xsl:template match="contact"> <xsl:if test="string-length(contelephone)!=0"> <div class="small bold">TELEPHONE:</div> <div class="large"> <xsl:value-of select="contelephone/." /> </div> </xsl:if> <xsl:if test="string-length(conmobile)!=0"> <div class="small bold">MOBILE:</div> <div class="large"> <xsl:value-of select="conmobile/." /> </div> </xsl:if> <xsl:if test="string-length(fax)!=0"> <div class="small bold">FAX:</div> <div class="large"> <xsl:value-of select="fax/." /> </div> </xsl:if> </xsl:template> and a section of my xml.

  • template class: ctor against function -> new C++ standard

    - by Oops
    Hi in this question: http://stackoverflow.com/questions/2779155/template-point2-double-point3-double Dennis and Michael noticed the unreasonable foolishly implemented constructor. They were right, I didn't consider this at that moment. But I found out that a constructor does not help very much for a template class like this one, instead a function is here much more convenient and safe namespace point { template < unsigned int dims, typename T > struct Point { T X[ dims ]; std::string str() { std::stringstream s; s << "{"; for ( int i = 0; i < dims; ++i ) { s << " X" << i << ": " << X[ i ] << (( i < dims -1 )? " |": " "); } s << "}"; return s.str(); } Point<dims, int> toint() { Point<dims, int> ret; std::copy( X, X+dims, ret.X ); return ret; } }; template < typename T > Point< 2, T > Create( T X0, T X1 ) { Point< 2, T > ret; ret.X[ 0 ] = X0; ret.X[ 1 ] = X1; return ret; } template < typename T > Point< 3, T > Create( T X0, T X1, T X2 ) { Point< 3, T > ret; ret.X[ 0 ] = X0; ret.X[ 1 ] = X1; ret.X[ 2 ] = X2; return ret; } template < typename T > Point< 4, T > Create( T X0, T X1, T X2, T X3 ) { Point< 4, T > ret; ret.X[ 0 ] = X0; ret.X[ 1 ] = X1; ret.X[ 2 ] = X2; ret.X[ 3 ] = X3; return ret; } }; int main( void ) { using namespace point; Point< 2, double > p2d = point::Create( 12.3, 34.5 ); Point< 3, double > p3d = point::Create( 12.3, 34.5, 56.7 ); Point< 4, double > p4d = point::Create( 12.3, 34.5, 56.7, 78.9 ); //Point< 3, double > p1d = point::Create( 12.3, 34.5 ); //no suitable user defined conversion exists //Point< 3, int > p1i = p4d.toint(); //no suitable user defined conversion exists Point< 2, int > p2i = p2d.toint(); Point< 3, int > p3i = p3d.toint(); Point< 4, int > p4i = p4d.toint(); std::cout << p2d.str() << std::endl; std::cout << p3d.str() << std::endl; std::cout << p4d.str() << std::endl; std::cout << p2i.str() << std::endl; std::cout << p3i.str() << std::endl; std::cout << p4i.str() << std::endl; char c; std::cin >> c; } has the new C++ standard any new improvements, language features or simplifications regarding this aspect of ctor of a template class? what do you think about the implementation of the combination of namespace, stuct and Create function? many thanks in advance Oops

  • Template problems: No matching function for call

    - by Nick Sweet
    I'm trying to create a template class, and when I define a non-member template function, I get the "No matching function for call to randvec()" error. I have a template class defined as: template <class T> class Vector { T x, y, z; public: //constructors Vector(); Vector(const T& x, const T& y, const T& z); Vector(const Vector& u); //accessors T getx() const; T gety() const; T getz() const; //mutators void setx(const T& x); void sety(const T& y); void setz(const T& z); //operations void operator-(); Vector plus(const Vector& v); Vector minus(const Vector& v); Vector cross(const Vector& v); T dot(const Vector& v); void times(const T& s); T length() const; //Vector<T>& randvec(); //operators Vector& operator=(const Vector& rhs); friend std::ostream& operator<< <T>(std::ostream&, const Vector<T>&); }; and the function in question, which I've defined after all those functions above, is: //random Vector template <class T> Vector<double>& randvec() { const int min=-10, max=10; Vector<double>* r = new Vector<double>; int randx, randy, randz, temp; const int bucket_size = RAND_MAX/(max-min +1); temp = rand(); //voodoo hackery do randx = (rand()/bucket_size)+min; while (randx < min || randx > max); r->setx(randx); do randy = (rand()/bucket_size)+min; while (randy < min || randy > max); r->sety(randy); do randz = (rand()/bucket_size)+min; while (randz < min || randz > max); r->setz(randz); return *r; } Yet, every time I call it in my main function using a line like: Vector<double> a(randvec()); I get that error. However, if I remove the template and define it using 'double' instead of 'T', the call to randvec() works perfectly. Why doesn't it recognize randvec()? P.S. Don't mind the bit labeled voodoo hackery - this is just a cheap hack so that I can get around another problem I encountered.

  • Extracting pair member in lambda expressions and template typedef idiom

    - by Nazgob
    Hi, I have some complex types here so I decided to use nifty trick to have typedef on templated types. Then I have a class some_container that has a container as a member. Container is a vector of pairs composed of element and vector. I want to write std::find_if algorithm with lambda expression to find element that have certain value. To get the value I have to call first on pair and then get value from element. Below my std::find_if there is normal loop that does the trick. My lambda fails to compile. How to access value inside element which is inside pair? I use g++ 4.4+ and VS 2010 and I want to stick to boost lambda for now. #include <vector> #include <algorithm> #include <boost\lambda\lambda.hpp> #include <boost\lambda\bind.hpp> template<typename T> class element { public: T value; }; template<typename T> class element_vector_pair // idiom to have templated typedef { public: typedef std::pair<element<T>, std::vector<T> > type; }; template<typename T> class vector_containter // idiom to have templated typedef { public: typedef std::vector<typename element_vector_pair<T>::type > type; }; template<typename T> bool operator==(const typename element_vector_pair<T>::type & lhs, const typename element_vector_pair<T>::type & rhs) { return lhs.first.value == rhs.first.value; } template<typename T> class some_container { public: element<T> get_element(const T& value) const { std::find_if(container.begin(), container.end(), bind(&typename vector_containter<T>::type::value_type::first::value, boost::lambda::_1) == value); /*for(size_t i = 0; i < container.size(); ++i) { if(container.at(i).first.value == value) { return container.at(i); } }*/ return element<T>(); //whatever } protected: typename vector_containter<T>::type container; }; int main() { some_container<int> s; s.get_element(5); return 0; }

  • A question about John Resig's Simple Javascript Inheritance.

    - by Zippo
    I'm using this simple code: http://ejohn.org/blog/simple-javascript-inheritance/ Using this "library", I made this simple class: var Person = Class.extend({ init: function(openningSentence) { this.say(openningSentence); }, say: function(words) { alert(words); } }); The problem with this class, is that I can't call a function using the variable "this" (line 3 in the code gives an error: unknown method "say"). Does anybody knoes if there's a solution for this problem? Btw - I'm using jquery, so if there's a jquery-based solution It'll be great :)

  • c++ global operator not playing well with template class

    - by John
    ok, i found some similar posts on stackoverflow, but I couldn't find any that pertained to my exact situation and I was confused with some of the answers given. Ok, so here is my problem: I have a template matrix class as follows: template <typename T, size_t ROWS, size_t COLS> class Matrix { public: template<typename, size_t, size_t> friend class Matrix; Matrix( T init = T() ) : _matrix(ROWS, vector<T>(COLS, init)) { /*for( int i = 0; i < ROWS; i++ ) { _matrix[i] = new vector<T>( COLS, init ); }*/ } Matrix<T, ROWS, COLS> & operator+=( const T & value ) { for( vector<T>::size_type i = 0; i < this->_matrix.size(); i++ ) { for( vector<T>::size_type j = 0; j < this->_matrix[i].size(); j++ ) { this->_matrix[i][j] += value; } } return *this; } private: vector< vector<T> > _matrix; }; and I have the following global function template: template<typename T, size_t ROWS, size_t COLS> Matrix<T, ROWS, COLS> operator+( const Matrix<T, ROWS, COLS> & lhs, const Matrix<T, ROWS, COLS> & rhs ) { Matrix<T, ROWS, COLS> returnValue = lhs; return returnValue += lhs; } To me, this seems to be right. However, when I try to compile the code, I get the following error (thrown from the operator+ function): binary '+=' : no operator found which takes a right-hand operand of type 'const matrix::Matrix<T,ROWS,COLS>' (or there is no acceptable conversion) I can't figure out what to make of this. Any help if greatly appreciated!

  • Unusual Template Behavior with XSL

    Experiencing some very odd behavior with, what should be, a very simple use of XSL and XSLT.

  • foswiki: hide some topic info when editing in WYSWYG mode.

    - by Mica
    I have a FOSWiki installation with a bunch of Topic templates already defined. the problem is, when a user selects the topic, they are presented with a bunch of extra information that they should not edit, and should not even see really. Is there a way to hide this content in the WYSWYG editor? Example: The topic template looks like this: <!-- * Foswiki.GenPDFAddOn Settings * Set GENPDFADDON_TITLE = <font size="7"><center>Foo</center></font> * Set GENPDFADDON_HEADFOOTFONT = helvetica * Set GENPDFADDON_FORMAT = pdf14 * Set GENPDFADDON_PERMISSIONS = print,no-copy * Set GENPDFADDON_ORIENTATION = portrait * Set GENPDFADDON_PAGESIZE = letter * Set GENPDFADDON_TOCLEVELS = 0 * Set GENPDFADDON_HEADERSHIFT = 0 --> <!-- PDFSTART --> <!-- HEADER LEFT "Foo:Bar" --> <!-- HEADER RIGHT "%BASETOPIC%" --> <!-- HEADER CENTER " " --> <!-- FOOTER RIGHT "Doc Rev %REVINFO{"r$rev - $date " web="%WEB%" topic="%BASETOPIC%"}%" --> <!-- FOOTER LEFT "F-xxx Rev A" --> <!-- FOOTER CENTER "Page $PAGE(1)" --> Header 1 foo etc. etc. etc <!-- pdfstop --> And when the user selects the topic template, they get all that in the WYSWYG editor. I would like to hide all that so when the user selects the topic template, they get Header 1 foo etc etc etc Without any of the other mark-up.

  • Customize the Five Windows Folder Templates

    - by Mark Virtue
    Are you’re particular about the way Windows Explorer presents each folder’s contents? Here we show you how to take advantage of Explorer’s built-in templates, which cuts down the time it takes to do customizations. Note: The techniques in this article apply to Windows XP, Vista, and Windows 7. When opening a folder for the first time in Windows Explorer, we are presented with a standard default view of the files and folders in that folder. It may be that the items are presented are perfectly fine, but on the other hand, we may want to customize the view.  The aspects of it that we can customize are the following: The display type (list view, details, tiles, thumbnails, etc) Which columns are displayed, and in which order The widths of the visible columns The order in which the files and folders are sorted Any file groupings Thankfully, Windows offers us a shortcut.  A particular folder’s settings can be used as a “template” for other, similar folders.  In fact, we can store up to five separate sets of folder presentation configurations.  Once we save the settings for a particular template, that template can then be applied to other folders. Customize Your First Folder We’ll start by setting up the first of our templates – the default one.  Once we create this template and apply it, the vast majority of the folders in our file system will change to match it, so it’s important that we set it up very carefully.  The first step in creating and applying the template is to customize one folder with the settings that all the rest will have. Choose a folder that is typical of the folders that you wish to have this default template.  Select it in Windows Explorer.  To ensure that it is a suitable candidate, right-click the folder name and select Properties, then go to the Customize tab.  Ensure that this folder is marked as General Items.  If it is not, either choose a different folder or select General Items from the list. Click OK.  Now we’re ready to customize our first folder. Changing the way one single folder is presented is straightforward.  We start with the folder’s display type.  Click the Change your view button in the top-right corner of every Explorer window. Each time you click the button, the folder’s view cycles to the next view type.  Alternatively you can click the little down-arrow next to the button to see all the display types at once, and select the one you want. Click the view you want, or drag the slider next to the one you want. If you have chosen Details, then the next thing you may wish to change is which columns are displayed, and the order of these.  To choose which columns are displayed, simply right-click on any column heading.  A list of the columns currently being display appears. Simply uncheck a column if you don’t want it displayed, and check the columns that you want displayed.  If you want some information displayed about your files that is not listed here, then click the More… button for a full list of file attributes. There’s a lot of them! To change the order of the columns that are currently being displayed, simply click on a column heading and drag it to where you think it should be.  To change the width of a column, click the line that represents the right-hand edge of the column and drag it left or right. To sort by a column, click once on that column.  To reverse the sort-order, click that same column again. To change the groupings of the files in the folder, right-click in a blank area of the folder, select Group by, and select the appropriate column. Apply This Default Template to All Similar Folders Once you have the folder exactly the way you want it, we now use this folder as our default template for most of the folders in our file system.  To do this, ensure that you are still in the folder you just customized, and then, from the Organize menu in Explorer, click on Folder and search options. Then select the View tab and click the Apply to Folders button. After you’ve clicked OK, visit some of the other folders in your file system.  You should see that most have taken on these new settings. What we’ve just done, in effect, is we have customized the General Items template.  This is one of five templates that Windows Explorer uses to display folder contents.  The five templates are called (in Windows 7): General Items Documents Pictures Music Videos When a folder is opened, Windows Explorer examines the contents to see if it can automatically determine which folder template to use to display the folder contents.  If it is not obvious that the folder contents falls into any of the last four templates, then Windows Explorer chooses the General Items template.  That’s why most of the folders in your file system are shown using the General Items template. Changing the Other Four Templates If you want to adjust the other four templates, the process is very similar to what we’ve just done.  If you wanted to change the “Music” template, for example, the steps would be as follows: Select a folder that contains music items Apply the existing Music template to the folder (even if it doesn’t look like you want it to) Customize the folder to your personal preferences Apply the new template to all “Music” folders A fifth step would be:  When you open a folder that contains music items but is not automatically displayed using the Music template, you manually select the Music template for that folder. First, select a folder that contains music items.  It will probably be displayed using the existing Music template: Next, ensure that it is using the Music template.  If it’s not, then manually select the Music template. Next, customize the folder to suit your personal preferences (here we’ve added a couple of columns, and sorted by Artist). Now we can set this view to be our Music template.  Choose Organize, then the View tab, and click the Apply to Folders button. Note: The only folders that will inherit these settings are the ones that are currently (or will soon be) using the Music template. Now, if you have any folder that contains music items, and you want it to inherit all of these settings, then right-click the folder name, choose Properties, and select that this folder should use the Music template.  You can also cehck the box entitled Also apply this template to all subfolders if you want to save yourself even more time with all the sub-folders. Conclusion It’s neat to be able to set up templates for your folder views like this.  It’s a shame that Microsoft didn’t take the concept just a little further and allow you to create as many templates as you want.

  • Windows ACL inheritance issues for FTP server and automated tools

    - by Martin Sall
    I have set up Cerberus FTP server. By default, Cerberus FTP service runs under SYSTEM ACCOUNT. Also I have some console applications which run as scheduled tasks. They are running under a dedicated "Utilities" user account which has "Log on as batch job" permissions. These console applications take uploaded FTP files, process them and then move them to some dedicated archive folder. The problem is that my console apps are throwing Security exceptions when trying to acces the uploaded files. I tried to give the Full control permissions on the ftproot folder for my "Utilities" account and I have checked that "Replace all Child object permissions with inheritable permissions from this object" checkbox, but it affects only current files. When new files are uploaded, they again are not accessible by my "Utilities" account. I tried to go another way and put Cerberus FTP service under "Utilities" account. Then I also needed to give "Utilities" account permissions on Cerberus Data folder in ProgramData. Still no luck - after this operation, Cerberus internal SOAP web service stopped working (although everything else seems to work). I need that SOAP service to be available, so running the Cerberus FTP under "Utilities" account seems to be not an option. Unless I find out, what else do I need to set up for that "Utilities" account to stop Cerberus from complaining. I guess, Cerberus is uploading files to some temporary folder and so those files get the permissions form that folder and keep the same permissions even after moved to the ftproot. What would be the right solution for this which would grant Cerberus FTP server and the "Utilities" account minimal needed permissions to access the contents of the ftproot folder?

  • Sharepoint 2007 reset permission inheritance

    - by e-mre
    I have this SharePoint 2007 document library which has several levels of folders and files. Some folders in the middle of the hierarchy do not inherit permissions from their parents and have their unique permissions defined. It is a huge library and there are many folders like this. I am currently changing the permission model of my library and I want to reset all those unique permissions and have all of them inherit permissions from the library root. (Something like "Replace child object permissions" checkbox available in windows files system security window) If this is not possible, seeing a list of folders that have their unique permissions defined would also do.
