OBJECTIVE-C CLASSES & OBJECTS http://www.tutorialspoint.com/objective_c/objective_c_classes_objects.htm Copyright © tutorialspoint.com The main purpose of Objective-C programming language is to add object orientation to the C programming language and classes are the central feature of Objective-C...
If you haven't already read Chapter 6, please do so before reading this one, because it provides a great introduction to some of the basics of Objective-C. This chapter builds on that foundation a bit more. By the end of this chapter, you can expect to have a greater understanding of...
Direct access is important in most communication between the DirectShow objects such as pins, allocators, and filters, and is the default method of communication. In fact, the base classes implement theIUnknowninterface on nonaggregated objects to call the nondelegating interface directly. The nonaggr...
-objc_msgSend()looks through the method list of the metaclass (and its superclasses, if any) to decide what method to call. Class methods are described by the metaclass on behalf of the class object, just like instance methods are described by the class on behalf of the instance objects...
data and methods. Instance variables (sometimes abbreviated as "ivars") are the data members of a class. Functions and operators are the methods of a C++ class. This section will use a common convention for the names of instance variables, member functions, objects, and classes. Names are co...
Classes and Objects One of the major advantages of using object-oriented programming is that programming can create modules that are reusable modules that need to be changed when a new type of object is added. While having basic knowledge of the java programming language you can learn to write...
//The following example attaches various HWNDs to the CWindow objects //and calls CWindow::CenterWindow() for each of them CWindow childWindow, popupWindow, overlappedWindow; childWindow.Attach(hWndChild); //a window created with WS_CHILD style childWindow.CenterWindow(); //This will center th...
You may also want to override the AssertValid function of CObject to provide customized testing to validate the consistency of the data members of class objects. For a description of how to override AssertValid, see MFC ASSERT_VALID and CObject::AssertValid....
