activateDeadManSwitch

private void activateDeadManSwitch(de.upb.swtpra.kernel.message.PleaseActivateDeadManSwitch msg)

This method will answer the call to an ActivateDeadManSwitch from the kernel with the corresponding message. The kernel will send the PleaseActivateDeadManSwitch whenever the shuttle was inactive for a longer time period. This is done to avoid dead shuttles in a running simulation. If the shuttle don't answer it is regarded as dead and gets disqualified after a time period long enough to send the answer.

Parameters:

msg - The received PleaseActivateDeadManSwitch
