Summary

Public Methods
abstract LongPredicate and(LongPredicate other)
Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
abstract LongPredicate negate()
Returns a predicate that represents the logical negation of this predicate.
abstract 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 abstract 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 abstract 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 abstract 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
