This interface allows definition for all of the indeterminate mutators in a CompositeMap, as well as providing a hook for callbacks on key collisions.
| 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. |
| Method Detail |
public void resolveCollision(CompositeMap composite,
Map existing,
Map added,
Collection intersect)
composite - the CompositeMap with the collisionexisting - the Map already in the composite which contains the
offending keyadded - the Map being addedintersect - the intersection of the keysets of the existing and added maps
public Object put(CompositeMap map,
Map[] composited,
Object key,
Object value)
map - the CompositeMap which is being modifiedcomposited - array of Maps in the CompositeMap being modifiedkey - key with which the specified value is to be associated.value - value to be associated with the specified key.
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.
public void putAll(CompositeMap map,
Map[] composited,
Map mapToAdd)
map - the CompositeMap which is being modifiedcomposited - array of Maps in the CompositeMap being modifiedmapToAdd - Mappings to be stored in this CompositeMap
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.
