class ObjCObjectPointerType

Declaration

class ObjCObjectPointerType : public Type, public Node { /* full declaration omitted */ };

Description

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 <P >' and 'Class <P >' 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.

    clang::ObjCInterfaceDecl* getInterfaceDecl() const

    Description

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

    Declared at: clang/include/clang/AST/Type.h:6259

    Returns

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

    const clang::ObjCInterfaceType* getInterfaceType()
    const

    Description

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

    Declared at: clang/include/clang/AST/Type.h:6253

    Returns

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

    unsigned int getNumProtocols() const

    Description

    Return the number of qualifying protocols on the object type.

    Declared at: clang/include/clang/AST/Type.h:6339

    const clang::ObjCObjectType* getObjectType() const

    Description

    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: For 'A*', getObjectType() will return 'A'. For 'A <P >*', getObjectType() will return 'A <P >'. For 'AP*', getObjectType() will return 'A <P >'. For 'A1*', getObjectType() will return 'A'. For 'A1 <P >*', getObjectType() will return 'A1 <P >'. For 'A1P*', getObjectType() will return 'A1 <P >'. 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).

    clang::QualType getPointeeType() const

    Description

    Gets the type pointed to by this ObjC pointer. The result will always be an ObjCObjectType or sugar thereof.

    Declared at: clang/include/clang/AST/Type.h:6219

    clang::ObjCProtocolDecl* getProtocol(
    unsigned int I) const

    Description

    Retrieve a qualifying protocol by index on the object type.

    Declared at: clang/include/clang/AST/Type.h:6344

    Parameters

    unsigned int I

    clang::QualType getSuperClassType() const

    Description

    Retrieve the type of the superclass of this object pointer type. This operation substitutes any type arguments into the superclass of the current class type, potentially producing a pointer to a specialization of the superclass type. Produces a null type if there is no superclass.
