Methods

¶CollectPPExpansions(
    clang::syntax::TokenCollector& C)

Declared at: clang/lib/Tooling/Syntax/Tokens.cpp:665

Parameters

clang::syntax::TokenCollector& C

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

Description

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

Declared at: clang/lib/Tooling/Syntax/Tokens.cpp:672

Parameters

const clang::Token& MacroNameTok

const clang::MacroDefinition& MD

clang::SourceRange Range

const clang::MacroArgs* Args

¶void disable()

Description

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.
