Description

Interface Summary

IAlert	passed to IProgram.wake(IDevice.IStatus, IAlert).
IDevice	programmable device.
IDevice.IConstants	constants.
IDevice.IDriver	driver.
IDevice.IDriver.IContainer	driver container.
IDevice.IStatus	status.
IDevice.IStatus.IFactory	produces status.
IInterpreter	command interpreter.
IPdCmd	for use where a String may not be used, because the command cannot conveniently be expressed as text.
IProgInfo	information about any IProgram an IDevice is running or has run.
IProgram	to be implemented by all programs.
IProgram.States	program states.
IStatusEtc	device status + program info.

Class Summary

Constants	passed to the constructors of the IMonitorGui and IControlsGui used by DiClient in order that any corr'ding GUIs provided by the device may be nested inside them.
DiClient	IDiClient for the deployment of programmable devices.
ProxyDevice	IDevice impl'n to be extended by all programmable-device definitions.
StartProgram	immutable command to start the specified program.
StatusPlusProgInfo	passed to the IMonitorGui.refresh(Object) method of the monitor window used by DiClient.

Exception Summary

ProxyDriverException

thrown by IDevice.IDriver methods as impl'ted by a dynamic proxy--see ProxyDevice.createProxyDriver(Class).

Package org.jmacs.pd Description

Programmable Device Framework. This is of interest to device-interface developers looking for programmatic (as well as interactive) monitoring and control. The package provides a framework for defining and deploying programmable devices, and for writing programs for them.

Programmable device definition involves writing a class ~.mydevice.MyDevice that implements IDevice (typically by extending ProxyDevice), and adding a nested IDevice.IDriver or IDevice.IDriver.IContainer named ~.mydevice.MyDevice.Driver or ~.mydevice.MyDevice.Container respectively. Similarly, any IMonitorGui, IControlsGui or command IInterpreter should be named ~.mydevice.MonitorGui, ~.mydevice.ControlsGui or ~.mydevice.Interpreter respectively. Please see the jmacs.org website for an example.

To deploy a programmable device, use DiClient.

To write a program for it, implement IProgram.
