public class CachedRowSetImpl
extends BaseRowSet
implements WLCachedRowSet, SyncResolver, Serializable, Cloneable

CachedRowSet is an implementation of the JDBC RowSet API (javax.sql.RowSet). This implementation provides a disconnected RowSet. The CachedRowSet is populated with data from a JDBC query or an existing JDBC ResultSet. At this point, the RowSet has all of the data in memory. The CachedRowSet uses the familiar ResultSet methods for reading, inserting, updating, and deleteting data. These operations only change the current copy of the data in memory. The data is not written back to the database until the acceptChanges method is called. The CachedRowSet uses optimistic concurrency when data is written back to the database. By default, the SQL UPDATE statement verifies that the data in the database matches what was read into the CachedRowSet. It is possible to select other Optimistic policies with the setOptimisticPolicy method.
