Examples of org.apache.commons.collections.MultiMap

org.apache.commons.collections.MultiMap
Defines a map that holds a collection of values against each key.
A MultiMap is a Map with slightly different semantics. Putting a value into the map will add the value to a Collection at that key. Getting a value will return a Collection, holding all the values put to that key.
For example:
```
 MultiMap mhm = new MultiHashMap(); mhm.put(key, "A"); mhm.put(key, "B"); mhm.put(key, "C"); Collection coll = (Collection) mhm.get(key);
```
coll will be a collection containing "A", "B", "C".
NOTE: Additional methods were added to this interface in Commons Collections 3.1. These were added solely for documentation purposes and do not change the interface as they were defined in the superinterface Map anyway. @since Commons Collections 2.0 @version $Revision: 1.12 $ $Date: 2004/03/14 15:33:57 $ @author Christopher Berry @author James Strachan @author Stephen Colebourne
