Constructor & Destructor Documentation

◆ CollectPPExpansions()

TokenCollector::CollectPPExpansions::CollectPPExpansions ( TokenCollector & C )

inline

Definition at line 617 of file Tokens.cpp.

Member Function Documentation

◆ disable()

void TokenCollector::CollectPPExpansions::disable ( )

inline

Disabled instance will stop reporting anything to TokenCollector.

This ensures that uses of the preprocessor after TokenCollector::consume() is called do not access the (possibly invalid) collector instance.

Definition at line 622 of file Tokens.cpp.

◆ MacroExpands()

void TokenCollector::CollectPPExpansions::MacroExpands	(	const clang::Token &	MacroNameTok,
		const MacroDefinition &	MD,
		SourceRange	Range,
		const MacroArgs *	Args
	)

inlineoverridevirtual

Called by Preprocessor::HandleMacroExpandedIdentifier when a macro invocation is found.

Reimplemented from clang::PPCallbacks.
