Method Summary

Modifier and Type	Method and Description
boolean	act(int events) Where acting takes place ... Hint: Can be used to process the events or input acquired from the previous step, or ... Key point: in the middle of a loop. Decision: to act on the next loop or not
int	breathe() Called when the star in on stage, just before acting. Hint: Can be used to poll events or get input/events from other sources, or ... Key point: a loop just started.
boolean	entract() Called as an interval between each act. Hint: Can be used to perform decisions to continue next loop or not, or to send computed data to outputs, or ... Key point: at the end of a loop. Decision: to act on the next loop or not
boolean	events(java.nio.channels.SelectableChannel channel, int events) Called when the poller intercepts events.
boolean	events(ZMQ.Socket socket, int events) Called when the poller intercepts events.
void	prepare() Called when the star is in the wings. Hint: Can be used to initialize the service, or ... Key point: no loop has started already.
boolean	renews() Does the star want to renew for a new performance ? Hint: Can be used to perform decisions to continue looping or not, or to send computed data to outputs, or ... Key point: the inner looping mechanism just ended Decision: to exit or not
