Public Attributes
StandardConversionSequence	Before
	Represents the standard conversion that occurs before the actual user-defined conversion.
bool	EllipsisConversion: 1
	EllipsisConversion - When this is true, it means user-defined conversion sequence starts with a ... (ellipsis) conversion, instead of a standard conversion.

After

StandardConversionSequence clang::UserDefinedConversionSequence::After

After - Represents the standard conversion that occurs after the actual user-defined conversion.

Before

StandardConversionSequence clang::UserDefinedConversionSequence::Before

Represents the standard conversion that occurs before the actual user-defined conversion.

C++11 13.3.3.1.2p1: If the user-defined conversion is specified by a constructor (12.3.1), the initial standard conversion sequence converts the source type to the type required by the argument of the constructor. If the user-defined conversion is specified by a conversion function (12.3.2), the initial standard conversion sequence converts the source type to the implicit object parameter of the conversion function.

ConversionFunction

FunctionDecl* clang::UserDefinedConversionSequence::ConversionFunction

ConversionFunction - The function that will perform the user-defined conversion.

Null if the conversion is an aggregate initialization from an initializer list.

Referenced by CompareImplicitConversionSequences(), dump(), FindConversionForRefInit(), IsInitializerListConstructorConversion(), IsUserDefinedConversion(), clang::Sema::PerformImplicitConversion(), TryReferenceInit(), and TryUserDefinedConversion().

EllipsisConversion

bool clang::UserDefinedConversionSequence::EllipsisConversion

EllipsisConversion - When this is true, it means user-defined conversion sequence starts with a ... (ellipsis) conversion, instead of a standard conversion.

In this case, 'Before' field must be ignored.

Definition at line 418 of file Overload.h.

Referenced by FindConversionForRefInit(), IsUserDefinedConversion(), and clang::Sema::PerformImplicitConversion().

FoundConversionFunction

DeclAccessPair clang::UserDefinedConversionSequence::FoundConversionFunction

The declaration that we found via name lookup, which might be the same as ConversionFunction or it might be a using declaration that refers to ConversionFunction.

Definition at line 437 of file Overload.h.

Referenced by FindConversionForRefInit(), IsInitializerListConstructorConversion(), IsUserDefinedConversion(), clang::Sema::PerformImplicitConversion(), and TryUserDefinedConversion().

HadMultipleCandidates

bool clang::UserDefinedConversionSequence::HadMultipleCandidates

HadMultipleCandidates - When this is true, it means that the conversion function was resolved from an overloaded set having size greater than 1.

Definition at line 423 of file Overload.h.
