Member Function Documentation

void wangle::AsyncSocketHandler::WriteCallback::writeErr ( size_t  bytesWritten, const folly::AsyncSocketException &  ex  )

inlineoverrideprivatevirtualnoexcept

writeError() will be invoked if an error occurs writing the data.

Parameters

bytesWritten	The number of bytes that were successfull
ex	An exception describing the error that occurred.

Implements folly::AsyncWriter::WriteCallback.

                        {
      promise_.setException(ex);
      delete this;
    }

void wangle::AsyncSocketHandler::WriteCallback::writeSuccess ( )

inlineoverrideprivatevirtualnoexcept

writeSuccess() will be invoked when all of the data has been successfully written.

Note that this mainly signals that the buffer containing the data to write is no longer needed and may be freed or re-used. It does not guarantee that the data has been fully transmitted to the remote endpoint. For example, on socket-based transports, writeSuccess() only indicates that the data has been given to the kernel for eventual transmission.
