Interface ForEachProcessor<T>

Type Parameters:

T - the type of the element

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 ForEachProcessor<T>

Represents a predicate (boolean-valued function) that accepts two input arguments and returns no result. The first input argument is int-valued and usually consuming the each index in an array or a list. The second input argument is usually consuming the each element in an array or a list.

Since:

Method Summary

Modifier and Type	Method	Description
default ForEachProcessor<T>	and(ForEachProcessor<? super T> other)	Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
default ForEachProcessor<T>	negate()	Returns a predicate that represents the logical negation of this predicate.
default ForEachProcessor<T>	or(ForEachProcessor<? super T> other)	Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.
boolean	process(int index, T elemnt)	Evaluates this predicate on the given arguments.

Method Detail

process

boolean process(int index,
                T elemnt)

Evaluates this predicate on the given arguments.

Parameters:

index - the index

elemnt - the element

Returns:

true if the input arguments match the predicate, otherwise false

and

default ForEachProcessor<T> and(ForEachProcessor<? super T> 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:

java.lang.NullPointerException - if other is null

negate

default ForEachProcessor<T> 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 ForEachProcessor<T> or(ForEachProcessor<? super T> 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:

java.lang.NullPointerException - if other is null
