union { ... }

◆ BuiltinParamTypes

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().

◆ Conversions

ConversionSequenceList clang::OverloadCandidate::Conversions

The conversion sequences used to convert the function arguments to the function parameters.

Definition at line 646 of file Overload.h.

Referenced by clang::OverloadCandidateSet::addCandidate().

◆ DeductionFailure

DeductionFailureInfo clang::OverloadCandidate::DeductionFailure

Definition at line 677 of file Overload.h.

◆ ExplicitCallArguments

unsigned clang::OverloadCandidate::ExplicitCallArguments

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

Definition at line 674 of file Overload.h.

Referenced by clang::Sema::AddBuiltinCandidate().

◆ FailureKind

unsigned char clang::OverloadCandidate::FailureKind

FailureKind - The reason why this candidate is not viable.

Actually an OverloadFailureKind.

Definition at line 670 of file Overload.h.

◆ FinalConversion

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.

◆ Fix

ConversionFixItGenerator clang::OverloadCandidate::Fix

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

Definition at line 649 of file Overload.h.

◆ FoundDecl

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 634 of file Overload.h.

Referenced by clang::Sema::AddBuiltinCandidate(), and clang::Sema::AddMethodCandidate().

◆ Function

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 629 of file Overload.h.

Referenced by clang::Sema::AddBuiltinCandidate(), and GetLocationForCandidate().

◆ IgnoreObjectArgument

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.

Definition at line 666 of file Overload.h.

Referenced by clang::Sema::AddBuiltinCandidate().

◆ IsSurrogate

bool clang::OverloadCandidate::IsSurrogate

IsSurrogate - True to indicate that this candidate is a surrogate for a conversion to a function pointer or reference (C++ [over.call.object]).

Definition at line 657 of file Overload.h.

Referenced by clang::Sema::AddBuiltinCandidate(), and GetLocationForCandidate().

◆ Surrogate

CXXConversionDecl* clang::OverloadCandidate::Surrogate

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

Definition at line 642 of file Overload.h.

Referenced by GetLocationForCandidate().

◆ Viable

bool clang::OverloadCandidate::Viable

Viable - True to indicate that this overload candidate is viable.

Definition at line 652 of file Overload.h.
