LongPredicate (Java Platform SE 8 ) (original) (raw)

• Functional Interface:
  This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface LongPredicate
Represents a predicate (boolean-valued function) of one long-valued argument. This is the long-consuming primitive type specialization ofPredicate.
This is a functional interface whose functional method is test(long).
Since:
1.8

  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](../../../java/util/function/LongPredicate.html "interface in java.util.function") and([LongPredicate](../../../java/util/function/LongPredicate.html "interface in java.util.function") 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](../../../java/lang/NullPointerException.html "class in java.lang")` \- if other is null  
     * #### negate  
     default [LongPredicate](../../../java/util/function/LongPredicate.html "interface in java.util.function") 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](../../../java/util/function/LongPredicate.html "interface in java.util.function") or([LongPredicate](../../../java/util/function/LongPredicate.html "interface in java.util.function") 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](../../../java/lang/NullPointerException.html "class in java.lang")` \- if other is null
