- public class VOMSTimer
- extends java.util.Timer
General timer for VOMS: a decorated singleton for Timer
that extends it with an interface for waiting for the currently running
timer (if any) to finish execution.
The timer thread is used by CAUpdater
to schedule updates on the CA
table and for various other periodic administrative activities.

isCancelled
public boolean isCancelled()
- Returns true if the timer has been cancelled. This should be
periodically checked in timer tasks to allow for a prompt service
shutdown.
Important note: timer tasks should store a reference to
their instance of VOMSTimer
, and their run()
methods should call isCancelled()
through that reference.
Calling isCancelled()
through theTimer()
always returns true, even if the currently running timer was cancelled.
