Class IloPredicate<>

The IloPredicate template class is the base class for all predicates. A predicate is a class that implements a test on an object (using operator()), and returns an IloBool value. Such classes can be used (along with classes of IloComparator) to parameterize selectors used in goal-based search.

Predicates can easily be built by using the ILOPREDICATE0 macros or by composing existing predicates and evaluators.

For more information, see Selectors.

This operator implements the test of an instance of class IloObject that may use a user-given context nu. If the predicate is a composite predicate (see operators on predicates), the context is also passed to components (predicates and evaluators) involved in the computation of the composite predicate.
