IROServerEventsBroker

Overview

The IROServerEventsBroker supports Event Sinks and Server Callbacks in scenarios when the client takes the active role of sending requests to the server, while the server passively waits for requests, processes them and sends back a response.

The TROInvoker class uses this interface for accessing TRORemoteDataModule methods.

The IROServerEventsBroker is used internally and should not be manipulated by the user.
