Scope

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.
