Class semper.util.msgtools.ChannelSetupMessage

java.lang.Object
   |
   +----semper.util.msgtools.ChannelSetupMessage

public class ChannelSetupMessage
extends Object
implements Streamable
Message sent while setting up a channel for negotiations. The initial message sets up a common context between the two parties by establishing the following:
  • Identifier of the object on the initiator side where the message originated. By convention, if the manager of the service was the initiator, then this is 0, otherwise it is the transaction/session id. This is just the recommended interpretation -- you can choose a different interpretation.
  • Identifier of the object on the responder side to which the message is destined
  • An external reference string, chosen on the initiator side and given back as return parameter on the responder side.
