union { ... }
QualType clang::OverloadCandidate::BuiltinParamTypes[3]

BuiltinParamTypes - Provides the parameter types of a built-in overload candidate.

Only valid when Function is NULL.

Definition at line 638 of file Overload.h.

Referenced by clang::Sema::AddBuiltinCandidate(), CompleteNonViableCandidate(), and NoteBuiltinOperatorCandidate().

ConversionSequenceList clang::OverloadCandidate::Conversions
DeductionFailureInfo clang::OverloadCandidate::DeductionFailure
unsigned clang::OverloadCandidate::ExplicitCallArguments
unsigned char clang::OverloadCandidate::FailureKind
StandardConversionSequence clang::OverloadCandidate::FinalConversion

FinalConversion - For a conversion function (where Function is a CXXConversionDecl), the standard conversion that occurs after the call to the overload candidate to convert the result of calling the conversion function to the required type.

Definition at line 683 of file Overload.h.

Referenced by clang::Sema::AddConversionCandidate(), and clang::isBetterOverloadCandidate().

ConversionFixItGenerator clang::OverloadCandidate::Fix

The FixIt hints which can be used to fix the Bad candidate.

Definition at line 649 of file Overload.h.

Referenced by CompleteNonViableCandidate(), DiagnoseBadConversion(), and TryToFixBadConversion().

DeclAccessPair clang::OverloadCandidate::FoundDecl
FunctionDecl* clang::OverloadCandidate::Function
bool clang::OverloadCandidate::IgnoreObjectArgument

IgnoreObjectArgument - True to indicate that the first argument's conversion, which for this function represents the implicit object argument, should be ignored.

This will be true when the candidate is a static member function (where the implicit object argument is just a placeholder) or a non-static member function when the call doesn't have an object argument.

bool clang::OverloadCandidate::IsSurrogate
CXXConversionDecl* clang::OverloadCandidate::Surrogate

Surrogate - The conversion function for which this candidate is a surrogate, but only if IsSurrogate is true.
