Interface QuadPredicate<A,B,C,D>

Type Parameters:
A - the type of the first argument to the predicate
B - the type of the second argument the predicate
C - the type of the third argument the predicate
D - the type of the fourth 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.
@FunctionalInterface public interface QuadPredicate<A,B,C,D>
Represents a predicate (boolean-valued function) of four arguments. This is the four-arity specialization of Predicate.

This is a functional interface whose functional method is test(Object, Object, Object, Object).

    Modifier and Type
    Method
    Description
    default QuadPredicate<A,B,C,D>
    and(QuadPredicate<? super A,? super B,? super C,? super D> other)
    Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
    default QuadPredicate<A,B,C,D>
    negate()
    Returns a predicate that represents the logical negation of this predicate.
    default QuadPredicate<A,B,C,D>
    or(QuadPredicate<? super A,? super B,? super C,? super D> other)
    Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.
    boolean
    test(A a, B b, C c, D d)
    Evaluates this predicate on the given arguments.

    • test

      boolean test(A a, B b, C c, D d)
      Evaluates this predicate on the given arguments.
      Parameters:
      a - the first input argument
      b - the second input argument
      c - the third input argument
      d - the fourth input argument
      Returns:
      true if the input arguments match the predicate, otherwise false

    • and

      default QuadPredicate<A,B,C,D> and(QuadPredicate<? super A,? super B,? super C,? super D> 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 is false, then the other 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, the other 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 the other predicate
      Throws:
      NullPointerException - if other is null

    • negate

      default QuadPredicate<A,B,C,D> 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 QuadPredicate<A,B,C,D> or(QuadPredicate<? super A,? super B,? super C,? super D> 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 is true, then the other 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, the other 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 the other predicate
      Throws:
      NullPointerException - if other is null
