Class Predicates<T>

java.lang.Object
org.eclipse.collections.impl.block.factory.Predicates<T>
All Implemented Interfaces:
Serializable, Predicate<T>, Predicate<T>
Direct Known Subclasses:
Predicates.AllSatisfy, Predicates.AnySatisfy, Predicates.NoneSatisfy
public abstract class Predicates<T> extends Object implements Predicate<T>
The Predicates class can be used to build common Predicates for use in methods such as detect, select and reject which are found on 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.

    • adapt

      public static <T> Predicates<T> adapt(Predicate<T> predicate)

    • cast

      public static <T> Predicate<T> cast(Predicate<T> predicate)
      Allows a Java 8 lambda or method reference to be used in a method taking a predicate without requiring an actual cast. This method can be used in places where two or more method overloads could apply when used with a lambda or method reference (e.g. removeIf).

    • throwing

      public static <T> Predicate<T> throwing(ThrowingPredicate<T> throwingPredicate)
      Allows a lambda or anonymous inner class that needs to throw a checked exception to be safely wrapped as a Predicate that will throw a RuntimeException, wrapping the checked exception that is the cause.

    • throwing

      public static <T> Predicate<T> throwing(ThrowingPredicate<T> throwingPredicate, Function2<T,? super Throwable,? extends RuntimeException> rethrow)
      Allows a lambda or anonymous inner class that needs to throw a checked exception to be safely wrapped as a Predicate that will throw a user specified RuntimeException based on the provided function. The function is passed the current element and the checked exception that was thrown as context arguments.
