Detailed Description

template<typename T, typename Predicate = boost::function1< bool, T >>
class WPredicateHelper::ArbitraryPredicate< T, Predicate >

The actual class implementing the predicate evaluation.

The default predicate is a functor evaluating to true or false. For more details see ArbitraryPredicateBase.

Template Parameters:

T	the type to check. This usually is the type of the elements in a list or similar.
Predicate	this is the predicate type. By default, it is a functor.
