Engine::SetDataRecvFunctor
Sets the callback function for an engine to receive messages. This API is defined in engine.h.
It must be used together with the DataRecvInterface::RecvData API. The detailed principles are as follows:
- Define a subclass (for example, DdkDataRecvInterface) of class DataRecvInterface and initialize the object of the subclass.
- Set the object of class DdkDataRecvInterface to a callback function by calling Engine::SetDataRecvFunctor.
- Send the input data to the corresponding output port by calling Engine::SendData.
- Return data by calling the RecvData function of class DdkDataRecvInterface.
