Interface LongPredicate

Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterfacepublic interfaceLongPredicate
Represents a predicate (boolean-valued function) of onelong-valued argument. This is thelong-consuming primitive type specialization ofPredicate.

This is afunctional interface whose functional method istest(long).

    Description
    Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
    Returns a predicate that represents the logical negation of this predicate.
    Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.

    Evaluates this predicate on the given argument.

  • Method Details

    • test

      boolean test(long value)
      Evaluates this predicate on the given argument.
      Parameters:
      value - the input argument
      Returns:
      true if the input argument matches the predicate, otherwisefalse

    • and

      default LongPredicate and(LongPredicate other)
      Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another. When evaluating the composed predicate, if this predicate isfalse, then theother predicate is not evaluated.

      Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, theother predicate will not be evaluated.

      Parameters:
      other - a predicate that will be logically-ANDed with this predicate
      Returns:
      a composed predicate that represents the short-circuiting logical AND of this predicate and theother predicate
      Throws:
      NullPointerException - if other is null

    • negate

      default LongPredicate negate()
      Returns a predicate that represents the logical negation of this predicate.
      Returns:
      a predicate that represents the logical negation of this predicate

    • or

      default LongPredicate or(LongPredicate other)
      Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another. When evaluating the composed predicate, if this predicate istrue, then theother predicate is not evaluated.

      Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, theother predicate will not be evaluated.

      Parameters:
      other - a predicate that will be logically-ORed with this predicate
      Returns:
      a composed predicate that represents the short-circuiting logical OR of this predicate and theother predicate
      Throws:
      NullPointerException - if other is null
