IROBinMessage

 

Sets SOAP attributes (SOAP message only)

procedure ApplyAttributes2

---

Sets transport related attributes (SOAP message only)

procedure ApplyAttributes2_Transport(aTransport: IROTransport)

Parameters:

• aTransport: Transport channel

---

Provides access to the ClientID read from the message. See event dispatching for a usage example.

property ClientID: TGUID read write

---

This method is called after all parameters have been written to a message and before the message will be sent. It should perform all necessary wrap-up to ensure that a subsequent call to WriteToStream will produce a complete message.
