Class ListMap

java.lang.Object
  |
  +--com.generationjava.collections.ListMap

All Implemented Interfaces:

java.util.Map

public class ListMap

extends java.lang.Object

implements java.util.Map

An Ordered Map. Values and keys are obtained in the order in which they were added. Sadly it is not possible to implement both Map and List due to method-signature clashes in the remove methods.
