Add all of the Objective-C methods in the given Objective-C container to the set of results.

The container will be a class, protocol, category, or implementation of any of the above. This mether will recurse to include methods from the superclasses of classes along with their categories, protocols, and implementations.

Parameters:

Container	the container in which we'll look to find methods.
WantInstanceMethods	Whether to add instance methods (only); if false, this routine will add factory methods (only).
CurContext	the context in which we're performing the lookup that finds methods.
AllowSameLength	Whether we allow a method to be added to the list when it has the same number of parameters as we have selector identifiers.
Results	the structure into which we'll add results.

When we have an expression with type "id", we may assume that it has some more-specific class type based on knowledge of common uses of Objective-C. This routine returns that class type, or NULL if no better result could be determined.

static NestedNameSpecifier* getRequiredQualification	(	ASTContext &	Context,

Compute the qualification required to get from the current context (CurContext) to the target context (TargetContext).

Parameters:

Context	the AST context in which the qualification will be used.
CurContext	the context where an entity is being named, which is typically based on the current scope.
TargetContext	the context in which the named entity actually resides.

Returns:: a nested name specifier that refers into the target context, or NULL if no qualification is needed.
