This interface allows definition for all of the indeterminate mutators in a CompositeMap, as well as providing a hook for callbacks on key collisions.

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

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. |
