Member Function Documentation

◆ completeVisibleDeclsMap()

void clang::ExternalSource::completeVisibleDeclsMap ( const clang::DeclContext * DC )

overridevirtual

Ensures that the table of all visible declarations inside this context is up to date.

The default implementation of this function is a no-op.

Reimplemented from clang::ExternalASTSource.

Definition at line 292 of file CodeCompletion.cpp.

References clang::NamedDecl::getDeclName(), clang::Decl::getPreviousDecl(), clang::DeclContext::hasExternalVisibleStorage(), clang::ExternalASTSource::SetExternalVisibleDeclsForName(), and clang::DeclContext::setHasExternalLexicalStorage().

◆ FindExternalVisibleDeclsByName()

bool clang::ExternalSource::FindExternalVisibleDeclsByName	(	const DeclContext *	DC,
		DeclarationName	Name,
		const DeclContext *	OriginalDC
	)

overridevirtual

Find all declarations with the given name in the given context, and add them to the context by calling SetExternalVisibleDeclsForName or SetNoExternalVisibleDeclsForName.

Parameters

DC	The context for lookup in. `DC` should be a primary context.
Name	The name to look for.
OriginalDC	The original context for lookup. `OriginalDC` can provide more information than `DC`. e.g., The same namespace can appear in multiple module units. So we need the `OriginalDC` to tell us what the module the lookup come from.

Returns: true if any declarations might have been found, false if we definitely have no declarations with tbis name.

The default implementation of this method is a no-op returning false.
