Detailed Description

Information about one declarator, including the parsed type information and the identifier.

When the declarator is fully formed, this is turned into the appropriate Decl object.

Declarators come in two types: normal declarators and abstract declarators. Abstract declarators are used when parsing types, and don't have an identifier. Normal declarators do have ID's.

Instances of this class should be a transient object that lives on the stack, not objects that are allocated in large quantities on the heap.

◆ Declarator()

clang::Declarator::Declarator	(	const DeclSpec &	DS,
		const ParsedAttributesView &	DeclarationAttrs,
		DeclaratorContext	C
	)

inline

DS and DeclarationAttrs must outlive the Declarator.

In particular, take care not to pass temporary objects for these parameters.

DeclarationAttrs contains [[]] attributes from the attribute-specifier-seq at the beginning of a declaration, which appertain to the declared entity itself. Attributes with other syntax (e.g. GNU) should not be placed in this attribute list; if they occur at the beginning of a declaration, they apply to the DeclSpec and should be attached to that instead.

Here is an example of an attribute associated with a declaration:

[[deprecated]] int x, y;

This attribute appertains to all of the entities declared in the declaration, i.e. x and y in this case.

Member Function Documentation

◆ AddInnermostTypeInfo()

void clang::Declarator::AddInnermostTypeInfo ( const DeclaratorChunk & TI )

inline

Add a new innermost chunk to this declarator.

◆ AddTypeInfo() [1/3]

void clang::Declarator::AddTypeInfo	(	const DeclaratorChunk &	TI,
		AttributePool &	OtherPool,
		SourceLocation	EndLoc
	)

inline

AddTypeInfo - Add a chunk to this declarator.

Also extend the range to EndLoc, which should be the last token of the chunk. This overload is for copying a 'chunk' from another declarator, so it takes the pool that the other Declarator owns so that it can 'take' the attributes from it.

◆ AddTypeInfo() [2/3]

void clang::Declarator::AddTypeInfo	(	const DeclaratorChunk &	TI,
		ParsedAttributes &&	attrs,
		SourceLocation	EndLoc
	)

inline

AddTypeInfo - Add a chunk to this declarator.

Also extend the range to EndLoc, which should be the last token of the chunk. This function takes attrs by R-Value reference because it takes ownership of those attributes from the parameter.

◆ AddTypeInfo() [3/3]
