Implementing the interface java.util.Enumeration passing the object
with JavaScript implementation directly to the constructor.
This is a shorthand for JavaAdapter constructor:
elements = new JavaAdapter(java.util.Enumeration, {
index: 0,
elements: array,
hasMoreElements: function ...
nextElement: function ...
});
*/
// an array to enumerate.
var array = [0, 1, 2];
// create an array enumeration.
var elements = new java.util.Enumeration({
index: 0,
elements: array,
hasMoreElements: function() {
return (this.index < this.elements.length);
},
nextElement: function() {
return this.elements[this.index++];
}
});
// now print out the array by enumerating through the Enumeration
while (elements.hasMoreElements())
print(elements.nextElement());
