Detailed Description

IdentifierResolver - Keeps track of shadowed decls on enclosing scopes.

It manages the shadowing chains of declaration names and implements efficient decl lookup based on a declaration name.

isDeclInScope()

bool IdentifierResolver::isDeclInScope	(	Decl *	D,
		DeclContext *	Ctx,
		Scope *	S = nullptr,
		bool	AllowInlineNamespace = false
	)		const

isDeclInScope - If 'Ctx' is a function/method, isDeclInScope returns true if 'D' is in Scope 'S', otherwise 'S' is ignored and isDeclInScope returns true if 'D' belongs to the given declaration context.

Parameters

AllowInlineNamespace

If true, we are checking whether a prior declaration is in scope in a declaration that requires a prior declaration (because it is either explicitly qualified or is a template instantiation or specialization). In this case, a declaration is in scope if it's in the inline namespace set of the context.

RemoveDecl()

void IdentifierResolver::RemoveDecl

(

NamedDecl *

D

)

RemoveDecl - Unlink the decl from its shadowed decl chain.

The decl must already be part of the decl chain.

tryAddTopLevelDecl()

bool IdentifierResolver::tryAddTopLevelDecl	(	NamedDecl *	D,
		DeclarationName	Name
	)

Try to add the given declaration to the top level scope, if it (or a redeclaration of it) hasn't already been added.

Parameters

D	The externally-produced declaration to add.
Name	The name of the externally-produced declaration.

Returns

true if the declaration was added, false otherwise.
