LongPredicate

  • LongPredicate is a functional interface representing a boolean-valued function that accepts a single long argument.

  • It provides methods to test the predicate against a long value (test), and to combine predicates using logical AND (and), OR (or), and negation (negate).

  • These methods allow for creating complex logical conditions by chaining and combining simple predicates.

  • The methods and and or are short-circuiting, meaning they may not evaluate the second predicate if the result can be determined from the first.
public interface LongPredicate

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

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

Public Method Summary

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

Public Methods

public LongPredicate and (LongPredicate 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 LongPredicate negate ()

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

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

public LongPredicate or (LongPredicate 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 (long value)

Evaluates this predicate on the given argument.

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