auto	MemberValid (T memberFunc)
	Returns a predicate that returns true if the isValid() method of the value returned from one of its member functions returns true.

auto	MemberIsAnyOf (T memberFunc, const C &container)
	Returns a predicate that returns true if the value returned by its argument's member function can be found in a captured container. More...

template<class T >
auto	Equals (T &&value)
	Returns a predicate that returns true if its argument compares equal with another, captured value.

template<class... Ts>
auto	EqualsByMembers (Ts... vs)
	Returns a predicate that returns true if its arguments compare equal to each other, considering only the captured members.

Function Documentation

template<class... Ts>

auto swift::misc::predicates::MemberEqual ( Ts... vs )

Predicate which tests whether some member functions return some values.

Parameters

vs	Pairs of { pointer to member function of T, value to compare it against }.

Returns: A unary functor whose operator() which will perform the actual test.

Definition at line 26 of file predicates.h.

template<class T , class C >

auto swift::misc::predicates::MemberIsAnyOf	(	T	memberFunc,
		const C &	container
	)

Returns a predicate that returns true if the value returned by its argument's member function can be found in a captured container.

Warning: The container is captured by reference, so be careful that it remains valid for the lifetime of the predicate.

Definition at line 75 of file predicates.h.

template<class... Ts>

auto swift::misc::predicates::MemberLess ( Ts... vs )

Predicate which compares the return values of some member functions of two objects.

Parameters

vs	Pointers to member functions of T.

Returns: A binary functor whose operator() which will perform the actual test.
