Class ConnectionProxy

Implemented Interfaces:
Connection
public class ConnectionProxy
extends java.lang.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.
