Class ConnectionWrapper

java.lang.Object
  extended by org.apache.cayenne.conn.ConnectionWrapper
All Implemented Interfaces:
Connection, Wrapper

public class ConnectionWrapper
extends Object
implements Connection

ConnectionWrapper is a java.sql.Connection implementation that wraps another Connection, delegating method calls to this connection. It works in conjunction with PooledConnectionImpl, to generate pool events, provide limited automated reconnection functionality, etc.
