const TypedefType *

getAs () const

This will check for a TypedefType by removing any existing sugar until it reaches a TypedefType or a non-sugared type.

Represents a pointer to an Objective C object.

These are constructed from pointer declarators when the pointee type is an ObjCObjectType (or sugar for one). In addition, the 'id' and 'Class' types are typedefs for these, and the protocol-qualified types 'id

' and 'Class

' are translated into these.

Pointers to pointers to Objective C objects are still PointerTypes; only the first level of pointer gets it own type implementation.

Definition at line 7585 of file Type.h.

const ObjCObjectType * clang::ObjCObjectPointerType::getObjectType ( ) const	inline

Gets the type pointed to by this ObjC pointer.

Always returns non-null.

This method is equivalent to getPointeeType() except that it discards any typedefs (or other sugar) between this type and the "outermost" object type. So for:

\@class A; \@protocol P; \@protocol Q;

typedef A

AP;

typedef A A1;

typedef A1

A1P;

typedef A1P A1PQ;

For 'A*', getObjectType() will return 'A'. For 'A

*', getObjectType() will return 'A

'. For 'AP*', getObjectType() will return 'A

'. For 'A1*', getObjectType() will return 'A'. For 'A1

*', getObjectType() will return 'A1

'. For 'A1P*', getObjectType() will return 'A1

'. For 'A1PQ*', getObjectType() will return 'A1', because adding protocols to a protocol-qualified base discards the old qualifiers (for now). But if it didn't, getObjectType() would return 'A1P' (and we'd have to make iterating over qualifiers more complicated).
