Detailed Description

DeclarationName - The name of a declaration. In the common case, this just stores an IdentifierInfo pointer to a normal name. However, it also provides encodings for Objective-C selectors (optimizing zero- and one-argument selectors, which make up 78% percent of all selectors in Cocoa.h) and special C++ names for constructors, destructors, and conversion functions.
