Enumeration Type Documentation

◆ PointerDeclaratorKind

enum PointerDeclaratorKind

strong

Describes the kind of a pointer a declarator describes.

Definition at line 3513 of file SemaType.cpp.

◆ PointerWrappingDeclaratorKind

enum PointerWrappingDeclaratorKind

strong

Describes a declarator chunk wrapping a pointer that marks inference as unexpected.

Definition at line 3531 of file SemaType.cpp.

◆ QualifiedFunctionKind

enum QualifiedFunctionKind

Kinds of declarator that cannot contain a qualified function type.

C++98 [dcl.fct]p4 / C++11 [dcl.fct]p6: a function type with a cv-qualifier or a ref-qualifier can only appear at the topmost level of a type.

Parens and member pointers are permitted. We don't diagnose array and function declarators, because they don't allow function types at all.

The values of this enum are used in diagnostics.

Definition at line 1911 of file SemaType.cpp.

◆ SimplePointerKind

enum SimplePointerKind

strong

A simple notion of pointer kinds, which matches up with the various pointer declarators.

Definition at line 3462 of file SemaType.cpp.

◆ TypeAttrLocation

enum TypeAttrLocation

The location of a type attribute.

Enumerator
TAL_DeclSpec	The attribute is in the decl-specifier-seq.
TAL_DeclChunk	The attribute is part of a DeclaratorChunk.
TAL_DeclName	The attribute is immediately after the declaration's name.

◆ checkNullabilityTypeSpecifier()

static bool checkNullabilityTypeSpecifier	(	TypeProcessingState &	state,
		QualType &	type,
		ParsedAttr &	attr,
		bool	allowOnArrayType
	)

static

Applies a nullability type specifier to the given type, if possible.

Parameters

state	The type processing state.
type	The type to which the nullability specifier will be added. On success, this type will be updated appropriately.
attr	The attribute as written on the type.
allowOnArrayType	Whether to accept nullability specifiers on an array type (e.g., because it will decay to a pointer).

Returns: true if a problem has been diagnosed, false on success.

◆ hasDirectOwnershipQualifier()

static bool hasDirectOwnershipQualifier ( QualType type )

static

Does this type have a "direct" ownership qualifier? That is, is it written like "__strong id", as opposed to something like "typeof(foo)", where that happens to be strong?

◆ hasOuterPointerLikeChunk()

static bool hasOuterPointerLikeChunk	(	const Declarator &	D,
		unsigned	endIndex
	)

static

Returns true if any of the declarator chunks before endIndex include a level of indirection: array, pointer, reference, or pointer-to-member.

Because declarator chunks are stored in outer-to-inner order, testing every chunk before endIndex is testing all chunks that embed the current chunk as part of their type.

It is legal to pass the result of Declarator::getNumTypeObjects() as the end index, in which case all chunks are tested.
