Class CopyOnWriteMap
java.lang.Object
helma.util.WrappedMap
helma.util.CopyOnWriteMap
- All Implemented Interfaces:
- java.util.Map
public class CopyOnWriteMap
- extends WrappedMap
A Map that wraps another map and creates a new copy of the
wrapped map if we try to modify it. This class is wrapped
as a native scripted object in JavaScript rather than exposing
them through Java reflection.
All methods in this class are synchronized in order not
to miss the switch between original and copied map.
