Detailed Description

ImplicitConversionSequence - Represents an implicit conversion sequence, which may be a standard conversion sequence (C++ 13.3.3.1.1), user-defined conversion sequence (C++ 13.3.3.1.2), or an ellipsis conversion sequence (C++ 13.3.3.1.3).

Member Enumeration Documentation

enum clang::ImplicitConversionSequence::CompareKind

Enumerator:

Better
Indistinguishable
Worse

Definition at line 458 of file Overload.h.

enum clang::ImplicitConversionSequence::Kind

Kind - The kind of implicit conversion sequence. BadConversion specifies that there is no conversion from the source type to the target type. AmbiguousConversion represents the unique ambiguous conversion (C++0x [over.best.ics]p10).

Enumerator:

StandardConversion
UserDefinedConversion
AmbiguousConversion
EllipsisConversion
BadConversion

unsigned clang::ImplicitConversionSequence::getKindRank ( ) const [inline]

Return a ranking of the implicit conversion sequence kind, where smaller ranks represent better conversion sequences.

In particular, this routine gives user-defined conversion sequences and ambiguous conversion sequences the same rank, per C++ [over.best.ics]p10.

bool clang::ImplicitConversionSequence::isInitialized ( ) const [inline]

Determines whether this conversion sequence has been initialized. Most operations should never need to query uninitialized conversions and should assert as above.
