Subject: Design Pattern
Keywords: Management of Event-based State-Actions

Abstract:

This Pattern is an extension of the well-known State pattern [Gam+95].
It allows an object to change its behaviour depending on the internal
state of the object. The behaviour is defined by events, whose concrete
transformation to actions depends on the object state. This pattern
introduces a way for the management of state actions.
