When closing the connection, the gateway can be configured to clear all the
messages in its queue. The following parameter is used to implement this task:
The configuration above would cause to gateway to delete all pending
messages/events while closing the connection to the client.
3.6 Events
In order to improve communication efficiency, most applications will require the client
to periodically poll for data changes with a higher priority than polling for other
monitored data. Every time a data point changes, the server can send this
information as an
event
, typically with date and time information indicating when the
change occurred.
The gateway supports a buffer queue of 99 events per data type. When the queue is
full, the gateway will delete the oldest event in the queue, replacing it with the
newest event received for that data type.
