BiPredicate

@FunctionalInterface interface BiPredicate<T : Any!, U : Any!>
java.util.function.BiPredicate

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

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

Summary

Public methods
open BiPredicate<T, U>!
and(other: BiPredicate<in T, in U>!)

Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.

open BiPredicate<T, U>!

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

open BiPredicate<T, U>!
or(other: BiPredicate<in T, in U>!)

Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.

abstract Boolean
test(t: T, u: U)

Evaluates this predicate on the given arguments.

Public methods

and

Added in API level 24
open fun and(other: BiPredicate<in T, in U>!): BiPredicate<T, U>!

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 BiPredicate<in T, in U>!: a predicate that will be logically-ANDed with this predicate
Return
BiPredicate<T, U>! a composed predicate that represents the short-circuiting logical AND of this predicate and the other predicate
Exceptions
java.lang.NullPointerException if other is null

negate

Added in API level 24
open fun negate(): BiPredicate<T, U>!

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

Return
BiPredicate<T, U>! a predicate that represents the logical negation of this predicate

or

Added in API level 24
open fun or(other: BiPredicate<in T, in U>!): BiPredicate<T, U>!

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 BiPredicate<in T, in U>!: a predicate that will be logically-ORed with this predicate
Return
BiPredicate<T, U>! a composed predicate that represents the short-circuiting logical OR of this predicate and the other predicate
Exceptions
java.lang.NullPointerException if other is null

test

Added in API level 24
abstract fun test(
    t: T,
    u: U
): Boolean

Evaluates this predicate on the given arguments.

Parameters
t T: the first input argument
u U: the second input argument
Return
Boolean true if the input arguments match the predicate, otherwise false
