• Method Summary

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

• Method Detail

  • test

    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

  • and

    default 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

  • negate

    default LongPredicate negate()

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

    Returns:

    a predicate that represents the logical negation of this predicate

  • or

    default 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
