ImplicitConversionSequence* clang::OverloadCandidate::Conversions

Conversions - The conversion sequences used to convert the function arguments to the function parameters, the pointer points to a fixed size array with NumConversions elements. The memory is owned by the OverloadCandidateSet.

unsigned clang::OverloadCandidate::ExplicitCallArguments

The number of call arguments that were explicitly provided, to be used while performing partial ordering of function templates.

unsigned char clang::OverloadCandidate::FailureKind

FailureKind - The reason why this candidate is not viable. Actually an OverloadFailureKind.

Definition at line 629 of file Overload.h.

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 642 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 605 of file Overload.h.

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

DeclAccessPair clang::OverloadCandidate::FoundDecl

FoundDecl - The original declaration that was looked up / invented / otherwise found, together with its access. Might be a UsingShadowDecl or a FunctionTemplateDecl.

Definition at line 585 of file Overload.h.

Referenced by clang::Sema::AddBuiltinCandidate(), clang::Sema::AddConversionCandidate(), clang::Sema::AddMethodCandidate(), clang::Sema::AddMethodTemplateCandidate(), clang::Sema::AddOverloadCandidate(), clang::Sema::AddSurrogateCandidate(), clang::Sema::AddTemplateConversionCandidate(), and clang::Sema::AddTemplateOverloadCandidate().

FunctionDecl* clang::OverloadCandidate::Function

Function - The actual function that this candidate represents. When NULL, this is a built-in candidate (C++ [over.oper]) or a surrogate for a conversion to a function pointer or reference (C++ [over.call.object]).

Definition at line 580 of file Overload.h.

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.
