Class ListMap

java.lang.Object
  com.tensegrity.generic.util.ListMap

All Implemented Interfaces:

java.util.Map

public class ListMap

extends java.lang.Object

implements java.util.Map

A ListMap is a simple Map implementation which basically acts like a normal HashMap. The difference between this class and a HashMap is the fact that this class returns an instance of class ListMapSet if the entrySet and keySet methods are called, which guarantees that the order is similar to one you had while adding the elements.
