Detailed Description

MinimalAction - Minimal actions are used by light-weight clients of the parser that do not need name resolution or significant semantic analysis to be performed. The actions implemented here are in the form of unresolved identifiers. By using a simpler interface than the SemanticAction class, the parser doesn't have to build complex data structures and thus runs more quickly.

Action::DeclPtrTy MinimalAction::ActOnDeclarator	(	Scope *	S,
		Declarator &	D
	)			`[virtual]`

ActOnDeclarator - If this is a typedef declarator, we modify the IdentifierInfo::FETokenInfo field to keep track of this fact, until S is popped.

Reimplemented from clang::Action.

Action::DeclPtrTy MinimalAction::ActOnForwardClassDeclaration	(	SourceLocation	AtClassLoc,
		IdentifierInfo **	IdentList,
		SourceLocation *	IdentLocs,
		unsigned	NumElts
	)			`[virtual]`

ActOnForwardClassDeclaration - Scope will always be top level file scope.

void MinimalAction::ActOnPopScope	(	SourceLocation	Loc,
		Scope *	S
	)			`[virtual]`

ActOnPopScope - When a scope is popped, if any typedefs are now out-of-scope, they are removed from the IdentifierInfo::FETokenInfo field.

Reimplemented from clang::Action.

void MinimalAction::ActOnTranslationUnitScope	(	SourceLocation	Loc,
		Scope *	S
	)			`[virtual]`

ActOnTranslationUnitScope - This callback is called once, immediately after creating the translation unit scope (in Parser::Initialize).

Reimplemented from clang::Action.

		SourceLocation	Loc,
		Scope *	S,
		CXXScopeSpec *	SS,
		bool	isClassName = `false`,
		TypeTy *	ObjectType = `0`
	)			`[virtual]`

getTypeName - This looks at the IdentifierInfo::FETokenInfo field to determine whether the name is a typedef or not in this scope.

Parameters:

	II	the identifier for which we are performing name lookup
	NameLoc	the location of the identifier
	S	the scope in which this name lookup occurs
	SS	if non-NULL, the C++ scope specifier that precedes the identifier
	isClassName	whether this is a C++ class-name production, in which we can end up referring to a member of an unknown specialization that we know (from the grammar) is supposed to be a type. For example, this occurs when deriving from "std::vector<T>::allocator_type", where T is a template parameter.

Returns:: the type referred to by this identifier, or NULL if the type does not name an identifier.

isTypeName - This looks at the IdentifierInfo::FETokenInfo field to determine whether the name is a type name (objc class name or typedef) or not in this scope.

FIXME: Use the passed CXXScopeSpec for accurate C++ type checking.

bool MinimalAction::isCurrentClassName	(	const IdentifierInfo &	II,
		Scope *	S,
		const CXXScopeSpec *	SS
	)			`[virtual]`

isCurrentClassName - Always returns false, because MinimalAction does not support C++ classes with constructors.

Implements clang::Action.

TemplateNameKind MinimalAction::isTemplateName	(	Scope *	S,
		CXXScopeSpec &	SS,
		UnqualifiedId &	Name,
		TypeTy *	ObjectType,
		bool	EnteringContext,
		TemplateTy &	Template,
		bool &	MemberOfUnknownSpecialization
	)			`[virtual]`

Determine whether the given name refers to a template.

This callback is used by the parser after it has seen a '<' to determine whether the given name refers to a template and, if so, what kind of template.

Parameters:

	S	the scope in which the name occurs.
	SS	the C++ nested-name-specifier that precedes the template name, if any.
	Name	the name that we are querying to determine whether it is a template.
	ObjectType	if we are determining whether the given name is a template name in the context of a member access expression (e.g., `p->X<int>`), this is the type of the object referred to by the member access (e.g., `p`).
	EnteringContext	whether we are potentially entering the context referred to by the nested-name-specifier `SS`, which allows semantic analysis to look into uninstantiated templates.
	Template	if the name does refer to a template, the declaration of the template that the name refers to.
	MemberOfUnknownSpecialization	Will be set true if the resulting member would be a member of an unknown specialization, in which case this lookup cannot possibly pass at this time.

Returns:: the kind of template that this name refers to.
