Detailed Description

Contains the DtCompositePredicate class declaration.

Instances of DtCompositePredicate maintain and evaluate a list of sub-predicates. An object will not pass an eval unless it passes the evals of all the predicates. Instances of DtCompositePredicate are not considered equal unless their predicate lists match.
