Scope

This document describes the Pin Keypad Device (PIN) classes 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 Device 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 Pin Keypad devices the basic Device Control structure is extended with
various properties and methods specific to this device which are described on the
following pages
