Class ArrayEnumeration

public class ArrayEnumeration

extends java.lang.Object

implements java.util.Enumeration

This class implements a simple Enumeration over an array.

When creating an ArrayEnumeration from an array of objects you optionally may specify the number of elements of the array that shall admit to the ArrayEnumeration, e.g.:

 SomeObject[] obj = ...;
 ArrayEnumeration arrayEnum = new ArrayEnumeration(obj, 2);
 

will create an ArrayEnumaeration of the first two elements of the given array of objects.

For getting the elements of an ArrayEnumeration use the hasMoreElements and nextElement methods, as already familiarly from the java.util.Enumeration, e.g.:

 
 for (; arrEnum.hasMoreElements() ; ) {
    System.out.println(arrayEnum.nextElement()); 
 }
