Member Function Documentation

void ExternalASTMerger::FindExternalLexicalDecls ( const DeclContext DC,
llvm::function_ref< bool(Decl::Kind)>  IsKindWeWant,
SmallVectorImpl< Decl * > &  Result 
)
overridevirtual

Finds all declarations lexically contained within the given DeclContext, after applying an optional filter predicate.

Parameters
IsKindWeWanta predicate function that returns true if the passed declaration kind is one we are looking for.

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

Reimplemented from clang::ExternalASTSource.

Definition at line 166 of file ExternalASTMerger.cpp.

References clang::ExternalASTMerger::ImporterPair::Forward, and clang::Decl::getDeclContext().

bool ExternalASTMerger::FindExternalVisibleDeclsByName ( const DeclContext DC,
DeclarationName  Name 
)
overridevirtual

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

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.

Reimplemented from clang::ExternalASTSource.
