Detailed Description

ObjCObjectPointerType - Used to represent 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.

Member Typedef Documentation

typedef ObjCObjectType::qual_iterator clang::ObjCObjectPointerType::qual_iterator

An iterator over the qualifiers on the object type. Provided for convenience. This will always iterate over the full set of protocols on a type, not just those provided directly.

getInterfaceDecl - If this pointer points to an Objective @interface type, gets the declaration for that interface.

Returns:: null if the base type for this pointer is 'id' or 'Class'

const ObjCInterfaceType* clang::ObjCObjectPointerType::getInterfaceType ( ) const [inline]

getInterfaceType - If this pointer points to an Objective C @interface type, gets the type for that interface. Any protocol qualifiers on the interface are ignored.

unsigned clang::ObjCObjectPointerType::getNumProtocols ( ) const [inline]

getNumProtocols - Return the number of qualifying protocols on the object type.

Definition at line 4590 of file Type.h.

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

getObjCObjectType - Gets the type pointed to by this ObjC pointer. This method 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<P> AP;
   typedef A A1;
   typedef A1<P> A1P;
   typedef A1P<Q> 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<Q>', because adding protocols to a protocol-qualified base discards the old qualifiers (for now). But if it didn't, getObjectType() would return 'A1P<Q>' (and we'd have to make iterating over qualifiers more complicated).
