enum.js
|
|
|
|
Implementing the interface java.util.Enumeration using the new syntax.
|
|
Note that this syntax is experimental only, and hasn't been approved
|
|
by ECMA.
|
|
The same functionality can be had without the new syntax using the
|
|
uglier syntax:
|
|
|
|
var elements = new JavaAdapter(java.util.Enumeration, {
|
|
index: 0, elements: array,
|
|
hasMoreElements: function ...
|
|
nextElement: function ...
|
|
});
|

// an array to enumerate.

var array = [0, 1, 2];

var elements = new java.util.Enumeration() {
