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

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

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.

Overrides:
createDeviceContext in class AbstractUDPDevice
Parameters:
deviceID - The device ID.
scheduler - The scheduler.
Returns:
The DeviceContext

main

public static void main(java.lang.String[] args)
A main method that runs an EchoDevice.
