Getting Timer Information

In addition to defining the cancel and getHandle methods, the Timer interface defines methods for obtaining information about timers:

public long getTimeRemaining();
public java.util.Date getNextTimeout();
public getInfo();

The getInfo method returns the object that was the last parameter of the createTimer invocation. For example, in the createTimer code snippet of the preceding section, this information parameter is a String object with the value created timer.

To retrieve all of a bean’s active timers, call the getTimers method of the TimerService interface. The getTimers method returns a collection of Timer objects.
