Class DCConnection

java.lang.Object
  org.lateralnz.c3d.DCConnection

All Implemented Interfaces:

java.io.Serializable, java.sql.Connection

public class DCConnection
extends java.lang.Object
implements java.sql.Connection, java.io.Serializable

an implementation of database connection. This also implements XAResource so we can provide some necessary functionality to the simpletrans package -- some of this stuff is a bit on the hacky side (with the excuse that some of the trans api docs are less than clear, and hardly what one could call straightforward to implement). I recommend -not- using this package if you're using any other transaction manager, because it is not correctly implemented (at the moment).
