Interface PredicateEx<T,E extends java.lang.Throwable>

Type Parameters:

T - the type of the input to the predicate

E - the type of exception could be thrown while performing operation

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 PredicateEx<T,E extends java.lang.Throwable>

Represents a predicate (boolean-valued function) of one argument.

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

Since:

1.8

Method Detail

isEqual

static <T,E extends java.lang.Throwable> PredicateEx<T,E> isEqual(java.lang.Object targetRef)
                                                           throws E extends java.lang.Throwable

Returns a predicate that tests if two arguments are equal according to Objects.equals(Object, Object).

Type Parameters:

T - the type of arguments to the predicate

Parameters:

targetRef - the object reference with which to compare for equality, which may be null

Returns:

a predicate that tests if two arguments are equal according to Objects.equals(Object, Object)

Throws:

E extends java.lang.Throwable

test

boolean test(T t)
      throws E extends java.lang.Throwable

Evaluates this predicate on the given argument.

Parameters:

t - the input argument

Returns:

true if the input argument matches the predicate, otherwise false

Throws:

E extends java.lang.Throwable

and

default PredicateEx<T,E> and(PredicateEx<? super T,E> other)
                      throws E extends java.lang.Throwable

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:

java.lang.NullPointerException - if other is null

E extends java.lang.Throwable

negate

default PredicateEx<T,E> negate()
                         throws E extends java.lang.Throwable

Returns a predicate that represents the logical negation of this predicate.

Returns:

a predicate that represents the logical negation of this predicate

Throws:

E extends java.lang.Throwable

or

default PredicateEx<T,E> or(PredicateEx<? super T,E> other)
                     throws E extends java.lang.Throwable

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 other is null

E extends java.lang.Throwable
