|
|
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];
|
|
|
|
// 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());
