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
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
