Detailed Description

A class for tracking whether we're inside a VA_OPT during a traversal of the tokens of a variadic macro definition.

◆ getUnmatchedOpeningParenLoc()

SourceLocation clang::VAOptDefinitionContext::getUnmatchedOpeningParenLoc ( ) const

Definition at line 97 of file VariadicMacroSupport.h.

Referenced by isConfigurationPattern().

◆ isInVAOpt()

bool clang::VAOptDefinitionContext::isInVAOpt ( ) const
inline

Returns true if we have seen the VA_OPT and '(' but before having seen the matching ')'.

Definition at line 88 of file VariadicMacroSupport.h.

◆ isVAOptToken()

bool clang::VAOptDefinitionContext::isVAOptToken ( const Token T) const
inline

◆ sawClosingParen()

bool clang::VAOptDefinitionContext::sawClosingParen ( )
inline

Call this function each time an rparen is seen.

It returns true only if the rparen that was just seen was the eventual (non-nested) closing paren for VAOPT, and ejects us out of the VAOPT context.

void clang::VAOptDefinitionContext::sawOpeningParen ( SourceLocation  LParenLoc)
inline

Call this function each time an lparen is seen.

◆ sawVAOptFollowedByOpeningParens()

void clang::VAOptDefinitionContext::sawVAOptFollowedByOpeningParens ( const SourceLocation  LParenLoc)
