Interface TimerManager

All Known Implementing Classes:

UCPTimerManagerImpl

public interface TimerManager

This interface decouples UCP and JAVA API/CommonJ timer implementations. IMPORTANT: The Timer Manager allows to run many timer tasks simultaneously, so a next 'schedule()' or 'scheduleAtFixedRate()' does not cancel previous one.

Method Summary

Modifier and Type	Method and Description
boolean	isRunning() Checks if manager is running.
TimerHandle	schedule(TimerTask task, long delay, long interval) Submits one timer task to execute periodically.
TimerHandle	scheduleAtFixedRate(TimerTask task, long delay, long interval) Submits one timer task to execute periodically at fixed rate.
void	start() Starts timer manager and prepares it to work.
void	stop() Shuts timer manager down and cleans everything up.

Method Detail

start

void start()

Starts timer manager and prepares it to work.

isRunning

boolean isRunning()

Checks if manager is running.

interval - task invocation interval in milliseconds.

scheduleAtFixedRate

TimerHandle scheduleAtFixedRate(TimerTask task,
                                long delay,
                                long interval)

Submits one timer task to execute periodically at fixed rate.

Parameters:

task - task to execute.
