Package net.sourceforge.jtds.jdbcx.proxy

Class ConnectionProxy

java.lang.Object
net.sourceforge.jtds.jdbcx.proxy.ConnectionProxy
All Implemented Interfaces:
AutoCloseable, Connection, Wrapper
public class ConnectionProxy extends Object implements Connection
This class would be better implemented as a java.lang.reflect.Proxy. However, this feature was not added until 1.3 and reflection performance was not improved until 1.4. Since the driver still needs to be compatible with 1.2 and 1.3 this class is used to delegate the calls to the connection with minimal overhead.
