clang: clang::OverloadCandidate Struct Reference

OverloadCandidate - A single candidate in an overload set (C++ 13.3). More...

#include "clang/Sema/Overload.h"

FunctionDecl * Function Function - The actual function that this candidate represents.
DeclAccessPair FoundDecl FoundDecl - The original declaration that was looked up / invented / otherwise found, together with its access.
QualType BuiltinParamTypes [3] BuiltinParamTypes - Provides the parameter types of a built-in overload candidate.
CXXConversionDecl * Surrogate Surrogate - The conversion function for which this candidate is a surrogate, but only if IsSurrogate is true.
ConversionSequenceList Conversions The conversion sequences used to convert the function arguments to the function parameters.
ConversionFixItGenerator Fix The FixIt hints which can be used to fix the Bad candidate.
unsigned Viable: 1 Viable - True to indicate that this overload candidate is viable.
unsigned Best: 1 Whether this candidate is the best viable function, or tied for being the best viable function.
unsigned IsSurrogate: 1 IsSurrogate - True to indicate that this candidate is a surrogate for a conversion to a function pointer or reference (C++ [over.call.object]).
unsigned IgnoreObjectArgument: 1 IgnoreObjectArgument - True to indicate that the first argument's conversion, which for this function represents the implicit object argument, should be ignored.
unsigned TookAddressOfOverload: 1 bool HasMatchedPackOnParmToNonPackOnArg: 1 Have we matched any packs on the parameter side, versus any non-packs on the argument side, in a context where the opposite matching is also allowed?
unsigned IsADLCandidate: 1 True if the candidate was found using ADL.
unsigned RewriteKind: 2 Whether this is a rewritten candidate, and if so, of what kind?
unsigned char FailureKind FailureKind - The reason why this candidate is not viable.
unsigned ExplicitCallArguments The number of call arguments that were explicitly provided, to be used while performing partial ordering of function templates.
union { DeductionFailureInfo DeductionFailure StandardConversionSequence 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.

OverloadCandidate - A single candidate in an overload set (C++ 13.3).

Definition at line 872 of file Overload.h.

◆ getNumParams() unsigned clang::OverloadCandidate::getNumParams ( ) const inline ◆ getRewriteKind() ◆ hasAmbiguousConversion() bool clang::OverloadCandidate::hasAmbiguousConversion ( ) const inline

hasAmbiguousConversion - Returns whether this overload candidate requires an ambiguous conversion or not.

Definition at line 974 of file Overload.h.

References clang::C, and Conversions.

◆ isReversed() bool clang::OverloadCandidate::isReversed ( ) const inline ◆ NotValidBecauseConstraintExprHasError() bool OverloadCandidate::NotValidBecauseConstraintExprHasError ( ) const ◆ TryToFixBadConversion() ◆ OverloadCandidateSet ◆ union { ... } clang::OverloadCandidate::@242 ◆ Best

Whether this candidate is the best viable function, or tied for being the best viable function.

For an ambiguous overload resolution, indicates whether this candidate was part of the ambiguity kernel: the minimal non-empty set of viable candidates such that all elements of the ambiguity kernel are better than all viable candidates not in the ambiguity kernel.

Definition at line 912 of file Overload.h.

◆ BuiltinParamTypes QualType clang::OverloadCandidate::BuiltinParamTypes[3] ◆ Conversions

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

Note that these are indexed by argument, so may not match the parameter order of Function.

◆ DeductionFailure ◆ 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 952 of file Overload.h.

◆ FailureKind unsigned char clang::OverloadCandidate::FailureKind

FailureKind - The reason why this candidate is not viable.

Actually an OverloadFailureKind.

Definition at line 948 of file Overload.h.

◆ FinalConversion ◆ Fix ◆ 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 882 of file Overload.h.

◆ 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]).
