com.apama.correlator
Event UserStatusChanged

EPL event containing delta for a user-added status item.

When a user status is changed, an event of this type will be sent to the channel with the prefix "com.apama.UserStatus:" followed by the status key, for example: "com.apama.UserStatus:myStatusKey".

Therefore, to subscribe to these updates, subscribe to the appropriate channel, for example: 
monitor.subscribe("com.apama.UserStatus:myStatusKey")
Additionally, a UserStatusChanged event will be sent (on the same channel described above) when a status key is added or removed. When added the previousValue will be "" and when removed the newValue will be "".
Since:
10.2
