Detailed Description

template<class W>
class grpc_impl::ClientAsyncWriter< W >

Async API on the client side for doing client-streaming RPCs, where the outgoing message stream going to the server contains messages of type W.

Member Function Documentation

Finish()

template<class W >

void grpc_impl::ClientAsyncWriter< W >::Finish ( ::grpc::Status *  status, void *  tag  )

inlineoverridevirtual

See the ClientAsyncStreamingInterface.Finish method for semantics.

Side effect:

• the ClientContext associated with this call is updated with possible initial and trailing metadata received from the server.
• attempts to fill in the response parameter passed to this class's constructor with the server's response message.

Implements grpc_impl::internal::ClientAsyncStreamingInterface.

operator delete() [1/2]

template<class W >

static void grpc_impl::ClientAsyncWriter< W >::operator delete ( void *  , std::size_t  size  )

inlinestatic

operator delete() [2/2]

template<class W >

static void grpc_impl::ClientAsyncWriter< W >::operator delete ( void *  , void *    )

inlinestatic

ReadInitialMetadata()

template<class W >

void grpc_impl::ClientAsyncWriter< W >::ReadInitialMetadata ( void *  tag )

inlineoverridevirtual

See the ClientAsyncStreamingInterface.ReadInitialMetadata method for semantics.

Side effect:

• upon receiving initial metadata from the server, the ClientContext associated with this call is updated, and the calling code can access the received metadata through the ClientContext.

Implements grpc_impl::internal::ClientAsyncStreamingInterface.

StartCall()

template<class W >

void grpc_impl::ClientAsyncWriter< W >::StartCall ( void *  tag )

inlineoverridevirtual

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.

Implements grpc_impl::internal::ClientAsyncStreamingInterface.

Write() [1/2]

template<class W >

void grpc_impl::ClientAsyncWriter< W >::Write ( const W &  msg, ::grpc::WriteOptions  options, void *  tag  )

inlineoverridevirtual

Request the writing of msg using WriteOptions options with identifying tag tag.

Only one write may be outstanding at any given time. This means that after calling Write, one must wait to receive tag from the completion queue BEFORE calling Write again. WriteOptions options is used to set the write options of this message. This is thread-safe with respect to AsyncReaderInterface::Read

gRPC doesn't take ownership or a reference to msg, so it is safe to to deallocate once Write returns.

Parameters

[in]	msg	The message to be written.
[in]	options	The WriteOptions to be used to write this message.
[in]	tag	The tag identifying the operation.

Implements grpc_impl::internal::AsyncWriterInterface< W >.

Write() [2/2]

template<class W >

void grpc_impl::ClientAsyncWriter< W >::Write ( const W &  msg, void *  tag  )

inlineoverridevirtual

Request the writing of msg with identifying tag tag.

Only one write may be outstanding at any given time. This means that after calling Write, one must wait to receive tag from the completion queue BEFORE calling Write again. This is thread-safe with respect to AsyncReaderInterface::Read

gRPC doesn't take ownership or a reference to msg, so it is safe to to deallocate once Write returns.

Parameters

[in]	msg	The message to be written.
[in]	tag	The tag identifying the operation.

Implements grpc_impl::internal::AsyncWriterInterface< W >.

WritesDone()

template<class W >

void grpc_impl::ClientAsyncWriter< W >::WritesDone ( void *  tag )

inlineoverridevirtual

Signal the client is done with the writes (half-close the client stream).

Thread-safe with respect to AsyncReaderInterface::Read

Parameters

[in]

tag

The tag identifying the operation.

Implements grpc_impl::ClientAsyncWriterInterface< W >.
