Method Detail

createTimerService

javax.ejb.TimerService createTimerService(javax.management.ObjectName containerId,
                                          Object pKey,
                                          Container container)
                                          throws IllegalStateException

Create a TimerService for a given containerId/pKey (TimedObjectId) that lives in a JBoss Container. The TimedObjectInvoker is constructed from the invokerClassName.

Parameters:

containerId - The string identifier for a class of TimedObjects

pKey - The primary key for an instance of a TimedObject, may be null

container - The Container that is associated with the TimerService

Returns:

the TimerService

Throws:

IllegalStateException

createTimerService

javax.ejb.TimerService createTimerService(javax.management.ObjectName containerId,
                                          Object pKey,
                                          TimedObjectInvoker invoker)
                                          throws IllegalStateException

Create a TimerService for a given containerId/pKey (TimedObjectId) that is invoked through the given invoker.

Parameters:

containerId - The string identifier for a class of TimedObjects

pKey - The primary key for an instance of a TimedObject, may be null

invoker - The TimedObjectInvoker

Returns:

the TimerService

Throws:

IllegalStateException

getTimerService

javax.ejb.TimerService getTimerService(javax.management.ObjectName containerId,
                                       Object pKey)
                                       throws IllegalStateException

Get the TimerService for a given containerId/pKey (TimedObjectId).

Parameters:

containerId - The string identifier for a class of TimedObjects

pKey - The primary key for an instance of a TimedObject, may be null

Returns:

The TimerService, or null if it does not exist

Throws:

IllegalStateException

removeTimerService

void removeTimerService(javax.management.ObjectName containerId,
                        Object pKey)
                        throws IllegalStateException

Remove the TimerService for a given containerId/pKey (TimedObjectId), along with any persisted timer information. This should be used for removing the TimerService and Timers associated with a particular entity bean, when it gets removed.

Parameters:

containerId - The string identifier for a class of TimedObjects

pKey - The primary key for an instance of a TimedObject, may be null

Throws:

IllegalStateException

removeTimerService

void removeTimerService(javax.management.ObjectName containerId,
                        boolean keepState)
                        throws IllegalStateException

Remove the TimerService for a given containerId. This should be used to remove the timer service and timers for any type of container (session, entity, message) at the time of undeployment.

Parameters:

containerId - The string identifier for a class of TimedObjects

keepState - Flag indicating whether timer persistent state should be kept or removed

Throws:

IllegalStateException

restoreTimers

void restoreTimers(javax.management.ObjectName containerId,
                   ClassLoader loader)
                   throws IllegalStateException

Restore the persisted timers for a given ejb container

Parameters:

containerId - The ejb container id

loader - The classloader to use for loading the timers

Throws:

IllegalStateException
