Interface MultiMap

All Superinterfaces:

Map

All Known Implementing Classes:

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.
