Summary

Public methods

default IntPredicate and(IntPredicate other)

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

default IntPredicate negate()

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

default IntPredicate or(IntPredicate other)

added in API level 24
public IntPredicate and (IntPredicate 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 IntPredicate: a predicate that will be logically-ANDed with this predicate

Returns
IntPredicate a composed predicate that represents the short-circuiting logical AND of this predicate and the other predicate

Throws
NullPointerException if other is null

negate

added in API level 24
public IntPredicate negate ()

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

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

or

added in API level 24
public IntPredicate or (IntPredicate 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 IntPredicate: a predicate that will be logically-ORed with this predicate

Returns
IntPredicate a composed predicate that represents the short-circuiting logical OR of this predicate and the other predicate

Throws
NullPointerException if other is null

test

added in API level 24
public abstract boolean test (int value)

Evaluates this predicate on the given argument.

Parameters
value int: the input argument

Returns
boolean true if the input argument matches the predicate, otherwise false
