Interface BiPredicate<T,U>

Type Parameters:
T - the type of the first argument to the predicate
U - the type of the second argument the predicate
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterfacepublic interfaceBiPredicate<T,U>
Represents a predicate (boolean-valued function) of two arguments. This is the two-arity specialization ofPredicate.

This is afunctional interface whose functional method istest(Object, Object).

    Modifier and Type
    Method
    Description
    defaultBiPredicate<T,U>
    and(BiPredicate<? superT, ? superU> other)
    Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
    defaultBiPredicate<T,U>
    Returns a predicate that represents the logical negation of this predicate.
    defaultBiPredicate<T,U>
    or(BiPredicate<? superT, ? superU> other)
    Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.
    boolean
    test(T t,U u)
    Evaluates this predicate on the given arguments.

  • Method Details

    • test

      boolean test(T t,U u)
      Evaluates this predicate on the given arguments.
      Parameters:
      t - the first input argument
      u - the second input argument
      Returns:
      true if the input arguments match the predicate, otherwisefalse

    • and

      default BiPredicate<T,U> and(BiPredicate<? superT, ? superU> 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 BiPredicate<T,U> 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 BiPredicate<T,U> or(BiPredicate<? superT, ? superU> 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
