The value from the map element that is denoted by the map iterator.
Remarks
Use the MapIterator.more method to test whether an element exists before you try to retrieve the key value of the map element.
The following example iterates through a map and returns a list of all the elements in the map.
static str writeMap (Map m)
{
MapIterator it = new MapIterator(m);
str result;
while (it.more())
{
result += it.key() + '\n' + it.value() + '\n';
it.next();
}
return result;
}
