Class CopyDataMessage (0.6.0)

public class CopyDataMessage extends ControlMessage

Normally used to send data to the back-end. Spanner does not currently support this, so send will throw a descriptive error to be sent to the user. Note that we do parse this in order for this to be future proof, and to ensure the input stream is flushed of the command (in order to continue receiving properly)
