method reset

This method sets the enumerator to its initial position, which, by default is before the first element of the collection.

var arrayObj = shell.serviceManager.basics.array;            
var enumerator = arrayObj.getEnumerator();
while (enumerator.moveNext())
{
    var name = enumerator.current;
}            
enumerator.reset();
while (enumerator.moveNext())
{
    var name = enumerator.current;
}
