EventPersister is a JMS message consumer that persists ObjectMessages. It listens to an XQueue and receives ObjectMessages from it. The incoming message is supposed to contain a task map and an event. EventPersister runs the task on the event as an EventAction and removes the message once it completes. So EventPersister is a worker executing the tasks of on-demand EventActions.

Here is an example of EventPersister:

{
  "Name": "pstr_pool",
  "ClassName": "org.qbroker.persister.EventPersister",
  "URI": "event://localhost",
  "Operation": "invoke",
  "LinkName": "pool",
  "DisplayMask": "2",
  "StringProperty": {
    "hostname": "",
    "name": "",
    "priority": ""
  }
}
