Interface SessionLog

All Superinterfaces:

SessionLog

All Known Implementing Classes:

AbstractSessionLog

public interface SessionLog

extends SessionLog

SessionLog is the ever-so-simple interface used by TopLink to log generated messages and SQL. An implementor of this interface can be passed to the TopLink session (via the #setSessionLog(SessionLog) method); and all logging data will be passed through to the implementor via an instance of SessionLogEntry. This can be used to supplement debugging; or the entries could be stored in a database instead of logged to System.out; etc.

Since:

TOPLink/Java 3.0
