Examples of DbOpReplicationContext

com.sleepycat.je.log.DbOpReplicationContext
This subclass of ReplicationContext adds information specific to database operations to the replication context passed from operation-aware code down the the logging layer. It's a way to transport enough information though the NameLNLogEntry to logically replicate database operations.
