Method Summary | |
---|---|
Object | put(CompositeMap map, Map[] composited, Object key, Object value)
Called when the CompositeMap.put() method is invoked.

void | putAll(CompositeMap map, Map[] composited, Map mapToAdd)
Called when the CompositeMap.putAll() method is invoked.
|
void | resolveCollision(CompositeMap composite, Map existing, Map added, Collection intersect)
Called when adding a new Composited Map results in a
key collision.

Parameters: map the CompositeMap which is being modified composited array of Maps in the CompositeMap being modified key key with which the specified value is to be associated. value value to be associated with the specified key.
Returns: previous value associated with specified key, or null if there was no mapping for key. A null return can also indicate that the map previously associated null with the specified key, if the implementation supports null values.
Throws: UnsupportedOperationException if not defined ClassCastException if the class of the specified key or value prevents it from being stored in this map. IllegalArgumentException if some aspect of this key or value prevents it from being stored in this map. NullPointerException this map does not permit null keys or values, and the specified key or value is null.
Parameters: map the CompositeMap which is being modified composited array of Maps in the CompositeMap being modified mapToAdd Mappings to be stored in this CompositeMap
Throws: UnsupportedOperationException if not defined ClassCastException if the class of the specified key or value prevents it from being stored in this map. IllegalArgumentException if some aspect of this key or value prevents it from being stored in this map. NullPointerException this map does not permit null keys or values, and the specified key or value is null.
Parameters: composite the CompositeMap with the collision existing the Map already in the composite which contains the offending key added the Map being added intersect the intersection of the keysets of the existing and added maps
