Listener Policy

Sometimes it is necessary to implement side-effects on other parts of the accounting system when records are inserted or removed from the system. For example:

• An allocation system might modify budget values.
• A table of aggregated records needs to be updated when new records are inserted into the master table

The Listener Policy allows record insert/delete operations to be forwarded to objects that implement the UsageRecordListener interface.

This policy is configured using the following configuration properties:

• ListenerPolicy.table-name This is a comma separated list of UsageRecordListener tables that should be notified when new records are inserted.
