## org.apache.cayenne.conn
Class ConnectionWrapper

    java.lang.Object
      org.apache.cayenne.conn.ConnectionWrapper

All Implemented Interfaces:
  Connection

    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.
