IROInvoker

Overview

The IROInvoker interface is used by the Remoting SDK invocation framework to invoke the actual methods on your service implementation. This interface is used internally by the TROMessageDispatcher in conjunction with the IROClassFactory interface to process an IROMessage. The TROInvoker class implements the IROInvoker interface. In _invk files generated by Remoting SDK for your services, the TROInvoker class is used as an ancestor for _Invoker classes, so they implement an IROInvoker interface. You hardly will have to deal with this interface.
