Interface ListenerMap<K,V>

All Superinterfaces:

Map<K,V>

All Known Implementing Classes:

ListenerHashMapImpl

public interface ListenerMap<K,V>
extends Map<K,V>

Interface of a map able to fire a property event whenever its data gets modified. The old/new value fields of the event must be filled according to the following system:

• When a new key-value pair is inserted into the map through the Map.put(java.lang.Object, java.lang.Object) method, the property name field must be key.toString(), the old value field must be set to null and the new value field to the new value.
• When an existing key-value pair is being overwritten through the Map.put(java.lang.Object, java.lang.Object) method, the property name field must be key.toString() and the old/new value fileds should reflect the old and new value.
• When a map of key-value pairs is inserted using Map.putAll(java.util.Map), the property name must be an empty string, old value must be null and new value should be the map of inserted values.
• When the map gets cleared through the Map.clear() method, the property name must be an empty string, old value must be a reference to this map and the new value must be set to null.
