Package Torello.Java.Function

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.

@FunctionalInterface
public interface IntBytePredicate

Function-Pointer Input: int, byte Output: boolean.

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:

 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:

 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:

 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);
