Request/Reply pattern

[ccy]

The Delphi-Event-Bus library works great for pub/sub pattern. Is that possible to use the library for request/reply pattern?

hi @ccy , might you provide an example to better understand the request?

Clear @ccy, it's simple using DEB - for example, this way:

1. you send an IRequest message from a TClient object, which also subscribes to the IReply message.
2. the TService object subscribes to the IRequest message. When it gets it it starts a worker thread and processes something there.... When it finishes, it sends an IResponse message
3. the TClient object receives an IResponse message when TService finishes processing its request.

Of course, you have to implement the IRequest, IResponse and TClient, TService types yourself, as you need them.
