Class Predicates<T>

java.lang.Object

org.eclipse.collections.impl.block.factory.Predicates<T>

All Implemented Interfaces:

Serializable, org.eclipse.collections.api.block.predicate.Predicate<T>

Direct Known Subclasses:

Predicates.AllSatisfy, Predicates.AnySatisfy, Predicates.NoneSatisfy

public abstract class Predicates<T>
extends Object
implements org.eclipse.collections.api.block.predicate.Predicate<T>

The Predicates class can be used to build common Predicates to be used by methods such as detect:, select: and reject: on the Iterate, MapIterate, and ArrayIterate classes. Predicates supports equals, not equals, less than, greater than, less than or equal to, greater than or equal to, in, not in and, or, and several other Predicate type operations.
