Interface IndexedPredicate<T>

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 IndexedPredicate<T>

Method Summary

Modifier and Type	Method and Description
default IndexedPredicate<T>	and(IndexedPredicate<? super T> other) Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
default IndexedPredicate<T>	negate() Returns a predicate that represents the logical negation of this predicate.
default IndexedPredicate<T>	or(IndexedPredicate<? super T> other) Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.
boolean	test(int index, T t) Evaluates this predicate on the given argument.

Method Detail

test

boolean test(int index,
             T t)

Evaluates this predicate on the given argument.

Parameters:

index - the index of [t]

t - the input argument

Returns:

true if the input argument matches the predicate, otherwise false

and

default IndexedPredicate<T> and(IndexedPredicate<? super T> 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 IndexedPredicate<T> 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 IndexedPredicate<T> or(IndexedPredicate<? super T> 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
