Detailed Description

Door is a simple component that utilizes just about every ACS API.

This class implements an example device "Door". It provides both synchronous (move(...)) and asynchronous methods (open() and close()). A control loop thread simulates the door's movements. Error and exception handling have been included. Asynchronous calls are implemented using the callback pattern via a support class. For each xxx action defined in the IDL interface two methods are provided:

• xxx() just registers the action and installs the callback
• xxxAction() performs (asyncronously) the action and invokes the callback when finished. The Door::invokeAction method is called by the asynchronous dispatcher whenever there is a xxx pending action and it calls the corresponding xxxAction method.
