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).

Definition at line 560 of file Overload.h.
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).

| void clang::ImplicitConversionSequence::DebugPrint | ( | ) | const |
DebugPrint - Print this implicit conversion sequence to standard error. Useful for debugging overloading issues.
Definition at line 487 of file SemaOverload.cpp.
| void clang::ImplicitConversionSequence::DiagnoseAmbiguousConversion | ( | Sema & | S, |
| SourceLocation | CaretLoc, | ||
| const PartialDiagnostic & | PDiag | ||
| ) | const |
Diagnoses an ambiguous conversion. The partial diagnostic is the "lead" diagnostic; it will be given two arguments, the source and target types of the conversion.

| 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.
