This document describes the Camera Device Class ( CAM ) based on the basic architecture of J/XFS which is similar to the JavaPOS architecture. It is event driven and asynchronous. Three basic levels are defined in JavaPOS. For J/XFS this model is extended by a communication layer, which provides device communication that allows distribution of applications and devices within a network. So we have the following layers in J/XFS: - Application - Device Control and Manager - Device Communication - Device Service Application developers program against control objects and the Device Manager which reside in the Device Control Layer. This is the usual interface between applications and J/XFS Devices. Device Control Objects access the Device Manager to find an associated Device Service. Device Service Objects provide the functionality to access the real device (i.e. like a device driver). During application startup the Device Manager is responsible for locating the desired Device Service Object and attaching this to the requesting Device Control Object. Location and/or routing information for the Device Manager reside in a central repository. To support Camera Devices, the basic Device Control structure is extended with various properties and methods specific to this device which are described on the following pages.
