I have a Perl module and I'd like to be able to pick out the parameters that my my module's user passed in the "use" call. Whichever ones I don't recognize I'd like to pass on. I tried to do this by overriding the "import" method but I'm not having much luck. EDIT: To clarify, as it is, I can use my module like this: use MyModule qw...
To use methods of a class I need to instantiate a class. At the moment the class has not constructor (so I want to write it). But than I have realized that the constructor should do nothing (I do need to specify values of fields). In this context I have a question if it is OK to write constructor which does nothing. For example: public...
I'm setting out to create an app where it will use 7-10 instances of a custom class, lets call them "books" each class will consist of a number of pages, a title, a int of how many pages a book contains and possibly some notes of the author associated with a specific page. My question is what is the best way of creating these objects. i...
I have a single xml file and every new thread of the program (BHO) is using the same Tinyxml file. every time a new window is open in the program, it runs this code: const char * xmlFileName = "C:\\browsarityXml.xml"; TiXmlDocument doc(xmlFileName); doc.LoadFile(); //some new lines in the xml.. and than save: doc.SaveFile(xmlFileName);...
Here is the function where I get the compiler warning, I can't seem to figure out what is causing it. Any help is appreciated. -(void)displaySelector{ //warning on the following line: InstanceSelectorViewController *controller = [[InstanceSelectorViewController alloc] initWithCreator:self]; [self.navController pushViewContr...
Hello, Here is the problem statement: Calling a setter on the object should result in the object to change to an object of a different class, which language can support this? Ex. I have a class called "Man" (Parent Class), and two children namely "Toddler" and "Old Man", they are its children because they override a behaviour in Man cal...
I have a menu click event that looks something like this.... Public Sub ToolbarManager_ToolClick(sender as Object, e as EventArgs) Case "New" CreateNewFile() Case "Save" SaveCurrentFile() Case "Exit" ExitApp() Case....... etc... etc... End Sub This strikes me as being 'ugly' - but I'm un...
Hi, Can anyone please tell me how I can free objects in C#? For example, I have an object: Object obj1 = new Object(); //Some code using obj1 /* Here I would like to free obj1, after it is no longer required and also more importantly its scope is the full run time of the program. */ Thanks for all your help ...

Hi, What would be the general structure of a App/Project based in C Programming language. libs, includes, header files. etc etc. What would be the class structure. (in OOps) need to be scalable and other features. Something like main.cpp main.h does any one have any good links or images or pdf? ...
Reading a book I have found the following statement: (Object) Behaviors answer either of two questions: What does this object do (for me)? or What can I do to this object? In the case of an orange, it doesn’t do a whole lot, but we can do things to it. One behavior is that it can be eaten. In my understanding of object behaviour th...
Say I have a class which represents a person, a variable within that class would be $name. Previously, In my scripts I would create an instance of the object then set the name by just using: $object->name = "x"; However, I was told this was not best practice? That I should have a function set_name() or something similar like this: f...
Hi all, as we know reference types are always stored on heap and value types are in stack memory. e.g. public Class A{ public int myInt=10; public void Display(){ } } here, if i create object of class A it goes in heap and myInt goes in stack right..? now, how class object (heap) interact with myInt public variable (stack)? ...
I have used the abstract factory pattern to help with Dependency Injection and make my project more unit test friendly. A good couple of times I have come across the point that we should return objects in a ready-to-use state. Doing extra work like getting an object's state from a database makes it harder to test unless we can mock out t...
what would be the difference between this class Class1 { public string prop1 { get; set; } public string prop2 { get; set; } public string prop3 { get; set; } public string prop4 { get; set; } } and this class Class2 { public string var1; public string var2; public string var3; public string var4; } ...
This may be a bit of daft question, but I don't come from an OOP background and although I'm reading and learning as I go I'm still struggling with a few concepts. Right now I'm working with PHP 5.3 and desiging a fairly simple login using a few different object classes: User which defines the user. Session which starts and maintains s...
Hi! I want to ask you to provide me with some articles (maybe books), which you possibly have found very convincing criticising the OOP methodology. I have read some in the WWW on this topic and I didn't really find a 'definitive demotivator'. It's not much about my personal attitude to the OOP, but I really would like to have somethi...

I have the mock object set similar to this: $stub = $this->getMock('SokmeClass', array('method')); $stub->expects($this->once()) ->method('method') ->with($this->equalTo($arg1)); Win the real class there is a variable that needs to be set for it to...
I have a question regarding the best way to implement this. I'm going to describe my current implementation and how I seem to have painted myself into a corner: I have an abstract class called Package: public abstract class Package { protected String description; protected String packagingCode; protected Dimension dimension...
