IntPredicate

  • IntPredicate is a functional interface representing a boolean-valued function that takes an int as input.

  • It provides methods for testing an int value against the predicate (test), as well as logically combining predicates using AND (and), OR (or), and negation (negate).

  • These methods allow for creating complex logical conditions for evaluating integer values.

  • It is a specialization of the Predicate interface for primitive int values.
public interface IntPredicate

Represents a predicate (boolean-valued function) of one int-valued argument. This is the int-consuming primitive type specialization of Predicate.

This is a functional interface whose functional method is test(int).

Public Method Summary

IntPredicate
and(IntPredicate other)
Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
IntPredicate
negate()
Returns a predicate that represents the logical negation of this predicate.
IntPredicate
or(IntPredicate other)
Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.
abstract boolean
test(int value)
Evaluates this predicate on the given argument.

Public Methods

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 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
NullPointerException if other is null

public IntPredicate negate ()

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

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

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 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
NullPointerException if other is null

public abstract boolean test (int value)

Evaluates this predicate on the given argument.

Parameters
value the input argument
Returns
  • true if the input argument matches the predicate, otherwise false
