Interface BytePredicate

  • 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 BytePredicate
    BytePredicate Documentation.

    This is similar to Java's IntPredicate, except it explicity requires a byte type in it's lambda 'test' method.




    • Method Detail

      • test

        boolean test​(byte b)
        Evaluates this predicate on the given argument.
        Parameters:
        b - primitive-byte input argument.
        Returns:
        TRUE if the input argument matches this predicate, and FALSE otherwise.
      • and

        default BytePredicate and​(BytePredicate 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 (byte b) -> this.test(b) && other.test(b);
        
      • negate

        default BytePredicate 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 (byte b) -> ! this.test(b);
        
      • or

        default BytePredicate or​(BytePredicate 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 (byte b) -> this.test(b) || other.test(b);
