- * TMap class
- *
- * TMap implements a collection that takes key-value pairs.
- *
- * You can access, add or remove an item with a key by using
- * {@link itemAt}, {@link add}, and {@link remove}.
- * To get the number of the items in the map, use {@link getCount}.
- * TMap can also be used like a regular array as follows,
- * <code>
- * $map[$key]=$value; // add a key-value pair
- * unset($map[$key]); // remove the value with the specified key
- * if(isset($map[$key])) // if the map contains the key
- * foreach($map as $key=>$value) // traverse the items in the map
- * $n=count($map); // returns the number of items in the map
- * </code>
