com.aendvari.common.util
Class MultiHashMap  

java.lang.Object
  com.aendvari.common.util.MultiHashMap

All Implemented Interfaces:

java.util.Map

---

public class MultiHashMap

extends java.lang.Object

implements java.util.Map

Implements java.util.Map using a java.util.HashMap. This Map class allows for multiple values for a single key.

Below is how the multi map is setup:

	HASH_MAP
	{
		HASH_KEY => (
				new Collection(
					Object, Object, etc...
				)
		),

		HASH_KEY => (
				new Collection(
					Object, Object, etc...
				)
		),

		etc...
	}
 

NOTE: This class DOES NOT implement the following:

• public void putAll(Map t)
