Interface Predicate4<T1,T2,T3,T4>

Type Parameters:

T1 - The type of the first argument to the predicate

T2 - The type of the second argument to the predicate

T3 - The type of the third argument to the predicate

T4 - The type of the fourth argument to the predicate

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 Predicate4<T1,T2,T3,T4>

Represents a predicate (boolean-valued function) of four arguments. This is the four-arity specialization of Predicate.

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

Since:

2.0.0

Method Summary

Modifier and Type	Method and Description
default Predicate4<T1,T2,T3,T4>	and(Predicate4<? super T1,? super T2,? super T3,? super T4> other) Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
default Function4<T1,T2,T3,T4,java.lang.Boolean>	boxed() Returns a Function4 with the result boxed to a Boolean.
default Predicate4<T1,T2,T3,T4>	negate() Returns a predicate that represents the logical negation of this predicate.
default Predicate4<T1,T2,T3,T4>	or(Predicate4<? super T1,? super T2,? super T3,? super T4> other) Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.
boolean	test(T1 t1, T2 t2, T3 t3, T4 t4) Evaluates this predicate on the given arguments.

Method Detail

test

boolean test(T1 t1,
             T2 t2,
             T3 t3,
             T4 t4)

Evaluates this predicate on the given arguments.

Parameters:

t1 - The first input argument

t2 - The second input argument

t3 - The third input argument

t4 - The fourth input argument

Returns:

true if the input arguments matches the predicate, otherwise false

and

default Predicate4<T1,T2,T3,T4> and(Predicate4<? super T1,? super T2,? super T3,? super T4> 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:

java.lang.NullPointerException - If other is null

negate

default Predicate4<T1,T2,T3,T4> negate()

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

Returns:

A predicate that represents the logical negation of this predicate

or

default Predicate4<T1,T2,T3,T4> or(Predicate4<? super T1,? super T2,? super T3,? super T4> 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:

java.lang.NullPointerException - If other is null

boxed

default Function4<T1,T2,T3,T4,java.lang.Boolean> boxed()

Returns a Function4 with the result boxed to a Boolean.

Returns:

A Function4 with the result boxed to a Boolean
