## Detailed Description

ObjCCategoryDecl - Represents a category declaration.

A category allows you to add methods to an existing class (without subclassing or modifying the original class interface or implementation:-). Categories don't allow you to add instance data. The following example adds "myMethod" to all NSView's within a process:

@interface NSView (MyViewMethods)

- myMethod; @end

Categories also allow you to split the implementation of a class across several files (a feature more naturally supported in C++).

Categories were originally inspired by dynamic languages such as Common Lisp and Smalltalk. More traditional class-based languages (C++, Java) don't support this level of dynamism, which is both powerful and dangerous.
