Interface MultiMap
- Map
- MultiHashMap
public interface MultiMap
extends Map
This is simply a Map with slightly different semantics.
Instead of returning an Object, it returns a Collection.
So for example, you can put( key, new Integer(1) );
and then a Object get( key ); will return you a Collection
instead of an Integer.
Thus, this is simply a tag interface.
Object | remove(Object key, Object item)
|
remove
public Object remove(Object key,
Object item)
