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

• Type Parameters:
  T - the type of the first argument to the predicate
  U - the type of the second argument the predicate
  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 BiPredicate<T,U>

1.8

  default BiPredicate<T,U>	and(BiPredicate<? super T,? super U> other)	Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
  default BiPredicate<T,U>	negate()	Returns a predicate that represents the logical negation of this predicate.
  default BiPredicate<T,U>	or(BiPredicate<? super T,? super U> other)	Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.
  boolean	test(T t,U u)	Evaluates this predicate on the given arguments.

     * #### test  
     boolean test([T](../../../java/util/function/BiPredicate.html "type parameter in BiPredicate") t,  
                  [U](../../../java/util/function/BiPredicate.html "type parameter in BiPredicate") u)  
     Evaluates this predicate on the given arguments.  
     Parameters:  
     `t` \- the first input argument  
     `u` \- the second input argument  
     Returns:  
     `true` if the input arguments match the predicate, otherwise `false`  
     * #### and  
     default [BiPredicate](../../../java/util/function/BiPredicate.html "interface in java.util.function")<[T](../../../java/util/function/BiPredicate.html "type parameter in BiPredicate"),[U](../../../java/util/function/BiPredicate.html "type parameter in BiPredicate")> and([BiPredicate](../../../java/util/function/BiPredicate.html "interface in java.util.function")<? super [T](../../../java/util/function/BiPredicate.html "type parameter in BiPredicate"),? super [U](../../../java/util/function/BiPredicate.html "type parameter in BiPredicate")> 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 [BiPredicate](../../../java/util/function/BiPredicate.html "interface in java.util.function")<[T](../../../java/util/function/BiPredicate.html "type parameter in BiPredicate"),[U](../../../java/util/function/BiPredicate.html "type parameter in BiPredicate")> 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 [BiPredicate](../../../java/util/function/BiPredicate.html "interface in java.util.function")<[T](../../../java/util/function/BiPredicate.html "type parameter in BiPredicate"),[U](../../../java/util/function/BiPredicate.html "type parameter in BiPredicate")> or([BiPredicate](../../../java/util/function/BiPredicate.html "interface in java.util.function")<? super [T](../../../java/util/function/BiPredicate.html "type parameter in BiPredicate"),? super [U](../../../java/util/function/BiPredicate.html "type parameter in BiPredicate")> 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
