Member Function Documentation

Finish()

template<class R >

virtual void grpc::ClientAsyncResponseReaderInterface< R >::Finish ( R *  msg, grpc::Status *  status, void *  tag  )

pure virtual

Request to receive the server's response msg and final status for the call, and to notify tag on this call's completion queue when finished.

This function will return when either:

• when the server's response message and status have been received.
• when the server has returned a non-OK status (no message expected in this case).
• when the call failed for some reason and the library generated a non-OK status.

Parameters

[in]	tag	Tag identifying this request.
[out]	status	To be updated with the operation status.
[out]	msg	To be filled in with the server's response message.

ReadInitialMetadata()

template<class R >

virtual void grpc::ClientAsyncResponseReaderInterface< R >::ReadInitialMetadata ( void *  tag )

pure virtual

Request notification of the reading of initial metadata. Completion will be notified by tag on the associated completion queue. This call is optional, but if it is used, it cannot be used concurrently with or after the Finish method.

Parameters

[in]

tag

Tag identifying this request.

StartCall()

template<class R >

virtual void grpc::ClientAsyncResponseReaderInterface< R >::StartCall ( )

pure virtual

Start the call that was set up by the constructor, but only if the constructor was invoked through the "Prepare" API which doesn't actually start the call
