Method Detail

and

public static <T> Predicate<T> and(Predicate<? super T>... predicates)

Returns a Predicate which evaluates to true only if all the provided predicates evaluate to true.

Parameters:

predicates - Predicate Predicates which will be ANDed together.

Returns:

A new Predicate which returns true only if all Predicate Predicates return true.

negate

public static <T> Predicate<T> negate(Predicate<? super T> p)

Returns a Predicate which negates the given Predicate.

Parameters:

p - the Predicate to negate

Returns:

A new Predicate which is always the opposite of the result of this Predicate.

or

public static <T> Predicate<T> or(Predicate<? super T> p1,
                                  Predicate<? super T> p2)

Returns a Predicate which evaluates to true if either this predicate or the provided predicate evaluate to true.

Parameters:

p1 - A Predicate which will be ORed together with p2.

p2 - A Predicate which will be ORed together with p1.

Returns:

A new Predicate which returns true if either Predicate returns true.

xor

public static <T> Predicate<T> xor(Predicate<? super T> p1,
                                   Predicate<? super T> p2)

Returns a Predicate which evaluates to true if either both Predicate Predicates return true or neither of them do.

Parameters:

p1 - A Predicate which will be XORed together with p2.

p2 - A Predicate which will be XORed together with p1.

Returns:

A new Predicate which returns true if both Predicate Predicates return true or neither of them do.
