Class TimerDevice

java.lang.Object
  extended by ist.palcom.device.AbstractDevice
      extended by ist.palcom.services.timer.TimerDevice
All Implemented Interfaces:
java.lang.Runnable

public class TimerDevice
extends AbstractDevice

This class implements the "Palcom" part of the timer device. One (in this case, the) important device-specific task is to initialize the DeviceIO and pass it to the DeviceContext.

TimerDevice

protected TimerDevice(java.lang.String name,
                      DeviceID deviceID)
Method Detail

initDevice

protected void initDevice()
                   throws java.io.IOException
Description copied from class: AbstractDevice
Initialize the device. Called from a PalcomThread. Here the actual setup is done. Subclasses override this method, and call super.initDevice from there.

Overrides:
initDevice in class AbstractDevice
Throws:
java.io.IOException

createDeviceContext

protected DeviceContext createDeviceContext(DeviceID deviceID,
                                            PalcomScheduler scheduler)
Description copied from class: AbstractDevice
Creates the DeviceContext of the device. This method has to be implemented in a concrete subclass.

Specified by:
createDeviceContext in class AbstractDevice
Parameters:
deviceID - The device ID.
scheduler - The scheduler.
Returns:
The DeviceContext

stopDevice

protected void stopDevice()
                   throws java.io.IOException
Description copied from class: AbstractDevice
Stop the device. Called from a PalcomThread. Here the actual cleanup is done. Subclasses override this method, and call super.stopDevice from there.

Overrides:
stopDevice in class AbstractDevice
Throws:
java.io.IOException
