Method Summary

Predicate2<A,B>	and(Evaluable2<? super A,? super B> other) Returns a predicate that performs a short-circuit logical-and between this Predicate2's Evaluable2.eval(Object,Object) and other
Predicate2<A,B>	not() Negates this Predicate
Predicate2<A,B>	nullSafe() Answers a Predicate2 that returns true if both arguments are null, false if only one of them is null, or evalutes this predicate, otherwise.
Predicate2<A,B>	or(Evaluable2<? super A,? super B> other) Returns a predicate that, performs a short-circuit logical-or between this Predicate2's Evaluable2.eval(Object,Object) and other
Predicate<Tuple2<A,B>>	uncurry() Uncurries this predicate, by returning a Predicate that takes a single pair, being its components each of the original predicate parameters

Method Detail

not

Predicate2<A,B> not()

Negates this Predicate

Returns:

a Predicate2 that negates this Predicate2's result.

or

Predicate2<A,B> or(@NonNull
                   Evaluable2<? super A,? super B> other)

Returns a predicate that, performs a short-circuit logical-or between this Predicate2's Evaluable2.eval(Object,Object) and other

Parameters:

other - another Evaluable2. Non null.

Returns:

A new predicate that performs the short circuited or between this and other when evaluated.

and

Predicate2<A,B> and(@NonNull
                    Evaluable2<? super A,? super B> other)

Returns a predicate that performs a short-circuit logical-and between this Predicate2's Evaluable2.eval(Object,Object) and other

Parameters:

other - another Evaluable2. Non null.

Returns:

A new predicate that performs the short circuited logical-and between this and other when evaluated. Non Null

nullSafe

@NullSafe
Predicate2<A,B> nullSafe()

Answers a Predicate2 that returns true if both arguments are null, false if only one of them is null, or evalutes this predicate, otherwise.

Specified by:

nullSafe in interface NullSafeAware<Predicate2<A,B>>

Returns:

a new null-safe Applicable of type A. Non null.

uncurry

Predicate<Tuple2<A,B>> uncurry()

Uncurries this predicate, by returning a Predicate that takes a single pair, being its components each of the original predicate parameters

Returns:

a new Predicate
