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.

◆ end()

◆ InsertDeclAfter()

)

◆ 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
AllowInlineNamespaceIf 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()

◆ 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
DThe externally-produced declaration to add.
NameThe name of the externally-produced declaration.
Returns
true if the declaration was added, false otherwise.
