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 ArrayExchanger

Exchanging interface, designed for exchanging (swapping) two elements in some data array.

The basic method swap(long, long) of this interface works with indexes of the exchanged elements in the array. So, every object, implementing this interface, is supposed to be working with some fixed linear data array. The method of storing data in the array can be any; for example, it can be an updatable AlgART array or a usual Java array. The length of the array is limited only by 263−1 (maximal possible value for long indexes).

This interface is used by ArraySorter class.

Note: UpdatableArray interface extends this interface.

In JArrays class you will find implementations of this interface for processing usual Java arrays.
