public interface FailablePredicate<T,E extends Exception>

Method Summary

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

Method Detail

test

boolean test(T t)
      throws E extends Exception

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 - in case of a failure evaluating the predicate

E extends Exception

and

default FailablePredicate<T,E> and(FailablePredicate<? super T,? extends E> 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 FailablePredicate<T,E> negate()

Returns:

a predicate that represents the logical negation of this predicate

or

default FailablePredicate<T,E> or(FailablePredicate<? super T,? extends E> 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
