abstract class %Library.ServerEventThe %ServerEvent class implements the interface for Server callbacks. Server connections can specify the name of a class derived from %ServerEvent. The server will then dispatch calls to methods implemented in that class when certain events occur in the server. Only three events dispatch calls to methods in the event class at this time. %OnConnect is called after the server has processed a new connection; %OnTranCommit is called after the server has processed a transaction commit; %OnTranRollback is called after the server has processed a transaction rollback.
