OverloadCandidateSet - A set of overload candidates, used in C++ overload resolution (C++ 13.3).

Definition at line 1021 of file Overload.h.

◆ iterator ◆ CandidateSetKind Enumerator CSK_Normal

Normal lookup.

CSK_Operator

C++ [over.match.oper]: Lookup of operator function candidates in a call using operator syntax.

Candidates that have no parameters of class type will be skipped unless there is a parameter of (reference to) enum type and the corresponding argument is of the same enum type.

CSK_InitByUserDefinedConversion

C++ [over.match.copy]: Copy-initialization of an object of class type by user-defined conversion.

CSK_InitByConstructor

C++ [over.match.ctor], [over.match.list] Initialization of an object of class type by constructor, using either a parenthesized or braced list of arguments.

CSK_AddressOfOverloadSet

C++ [over.match.call.general] Resolve a call through the address of an overload set.

◆ addCandidate() ◆ allocateConversionSequences() ◆ begin() iterator clang::OverloadCandidateSet::begin ( ) inline ◆ BestViableFunction()

Find the best viable function on this overload set, if it exists.

Computes the best viable function (C++ 13.3.3) within an overload candidate set.

Parameters: Loc The location of the function name (or operator symbol) for which overload resolution occurs. Best If overload resolution was successful or found a deleted function, Best points to the candidate function found.

Returns: The result of overload resolution.
