Interface IntBytePredicate

  • Functional Interface:
    This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

    public interface IntBytePredicate
    IntBytePredicate Documentation.

    This is a predicate having a 'test(...)' method which accepts two primitives-type parameters as follows type:

    1. 'int'
    2. 'byte'


    The output of the test(...) method is, naturally, a boolean.



    • Method Detail

      • test

        boolean test​(int i,
                     byte b)
        Evaluates this predicate on the given arguments.
        Parameters:
        i - The integer (first) argument to the predicate.
        b - The byte (second) argument to the predicate.
        Returns:
        TRUE if the input arguments match this predicate, and FALSE otherwise.
      • and

        default IntBytePredicate and​(IntBytePredicate 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-AND'ed with this predicate
        Returns:
        A composed predicate that represents the short-circuiting logical AND of this predicate and the other predicate
        Throws:
        java.lang.NullPointerException - if parameter 'other' is null.
        Code:
        Exact Method Body:
        1
        2
        3
        4
         if (other == null)
             throw new NullPointerException("null has been passed to parameter 'other");
        
         return (int i, byte b) -> this.test(i, b) && other.test(i, b);
        
      • negate

        default IntBytePredicate negate()
        Returns a predicate that represents the logical negation of this predicate.
        Returns:
        A predicate that represents the logical negation of this predicate
        Code:
        Exact Method Body:
        1
         return (int i, byte b) -> ! this.test(i, b);
        
      • or

        default IntBytePredicate or​(IntBytePredicate 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:
        java.lang.NullPointerException - if parameter 'other' is null.
        Code:
        Exact Method Body:
        1
        2
        3
        4
         if (other == null)
             throw new NullPointerException("null has been passed to parameter 'other");
        
         return (int i, byte b) -> this.test(i, b) || other.test(i, b);
