Member Enumeration Documentation

enum clang::OverloadCandidateSet::CandidateSetKind

Enumerator:

CSK_Normal	Normal lookup.
CSK_Operator	Lookup for candidates for 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.

OverloadingResult OverloadCandidateSet::BestViableFunction	(	Sema &	S,
		SourceLocation	Loc,
		OverloadCandidateSet::iterator &	Best,
		bool	UserDefinedConversion = false
	)

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.
