Methods

¶FunctionCallFilterCCC(
    clang::Sema& SemaRef,
    unsigned int NumArgs,
    bool HasExplicitTemplateArgs,
    clang::MemberExpr* ME = nullptr)

Declared at: clang/include/clang/Sema/TypoCorrection.h:381

Parameters

clang::Sema& SemaRef

unsigned int NumArgs

bool HasExplicitTemplateArgs

clang::MemberExpr* ME = nullptr

¶bool ValidateCandidate(
    const clang::TypoCorrection& candidate)

Description

Simple predicate used by the default RankCandidate to determine whether to return an edit distance of 0 or InvalidDistance. This can be overridden by validators that only need to determine if a candidate is viable, without ranking potentially viable candidates. Only ValidateCandidate or RankCandidate need to be overridden by a callback wishing to check the viability of correction candidates. The default predicate always returns true if the candidate is not a type name or keyword, true for types if WantTypeSpecifiers is true, and true for keywords if WantTypeSpecifiers, WantExpressionKeywords, WantCXXNamedCasts, WantRemainingKeywords, or WantObjCSuper is true.

Declared at: clang/include/clang/Sema/TypoCorrection.h:385

Parameters

const clang::TypoCorrection& candidate

¶std::unique_ptr<CorrectionCandidateCallback>
clone()

Description

Clone this CorrectionCandidateCallback. CorrectionCandidateCallbacks are initially stack-allocated. However in case where delayed typo-correction is done we need to move the callback to storage with a longer lifetime. Every class deriving from CorrectionCandidateCallback must implement this method.
