Detailed Description

Records information reqired to construct mappings for the token buffer that we are collecting.

Definition at line 615 of file Tokens.cpp.

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.

Definition at line 624 of file Tokens.cpp.
