Package	system.data.maps
Class	public dynamic class HashMap
Inheritance	HashMap Object
Implements	Map

Hash table based implementation of the Map interface. This implementation provides all of the optional map operations, and permits null values and the null key.

This class makes no guarantees as to the order of the map; in particular, it does not guarantee that the order will remain constant over time.

Example :

     import system.data.Map ;
     import system.data.maps.HashMap;
     import system.data.iterator.Iterator;
     
     var map:Map = new HashMap() ;
     
     trace("put key1 -> value0 : " + map.put("key1", "value0") ) ;
     trace("put key1 -> value1 : " + map.put("key1", "value1") ) ;
     trace("put key2 -> value2 : " + map.put("key2", "value2") ) ;
     trace("put key3 -> value3 : " + map.put("key3", "value3") ) ;
     
     trace("map : " + map) ;
     
     trace("--- clone") ;
     
     var clone:Map = map.clone() ;
     trace("clone : " + clone) ;
     
     trace("--- map toSource") ;
     
     trace("map toSource : " + map.toSource()) ;
     
     trace("--- iterator") ;
     
     var it:Iterator = map.iterator() ;
     while( it.hasNext() )
     {
         var v:= it.next() ;
         var k:= it.key() ;
         trace( "   -> " + k + " : " + v ) ;
     }
     
     trace("--- dynamic insertion ") ;
     
     map["key4"] = "value4" ; // dynamic insertion
     
     trace("map : " + map) ;
     
     trace("--- use delete") ;
     
     delete map["key4"] ;
     
     trace(" map : " + map) ;
     
     trace("--- remove 'key1'") ;
     
     trace("remove key1 : " + (delete map["key1"]) ) ; //.remove("key1")) ;
     
     trace("size : " + map.size()) ;
     
     trace("map : " + map) ;
     
     trace("--- clear and isEmpty") ;
     
     map.clear() ;
     
     trace("isEmpty : " + map.isEmpty()) ;
