- public class FSMContext
- extends java.util.Hashtable
This is the context of a FSM. A context holds a reference to the current state
and also functions as a repository for objects. To do that it extends from
java.util.Hashtable. Objects can be stored with the hashtable's put method and
retrieved with the hashtables get method.
