Modifier and Type	Method and Description
default SerializablePredicate<T>	and(SerializablePredicate<? super T> other) Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.

Method Detail

and

default SerializablePredicate<T> and(SerializablePredicate<? 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

Since:

8.5

negate

default SerializablePredicate<T> negate()

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

Specified by:

negate in interface Predicate<T>

Returns:

a predicate that represents the logical negation of this predicate

Since:

8.5

or

default SerializablePredicate<T> or(SerializablePredicate<? 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

Since:

8.5

isEqual

static <T> SerializablePredicate<T> isEqual(Serializable targetRef)

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)
