Class CachedRowSetResultSetProxyLogic

java.lang.Object

net.ttddyy.dsproxy.proxy.ProxyLogicSupport

net.ttddyy.dsproxy.proxy.CachedRowSetResultSetProxyLogic

All Implemented Interfaces:

ResultSetProxyLogic

public class CachedRowSetResultSetProxyLogic
extends ProxyLogicSupport
implements ResultSetProxyLogic

Uses CachedRowSet to provide repeatable read ResultSet proxy. CachedRowSet is disconnected scrollable RowSet which is a subset of ResultSet. Using those feature to provide repeatable read resultset proxy. The default oracle jdk implementation com.sun.rowset.CachedRowSetImpl does not support isClosed method. Thus, keep close status and return it when isClosed() is called.
