Member Function Documentation

virtual void folly::AsyncWriter::WriteCallback::writeErr ( size_t  bytesWritten,
const AsyncSocketException &  ex 
)
pure virtualnoexcept

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

Parameters
bytesWrittenThe number of bytes that were successfull
exAn exception describing the error that occurred.

Implemented in folly::SSLHandshakeBase, folly::SSLClient, folly::SNIClient, folly::AlpnClient, proxygen::HTTPSession::WriteSegment, folly::BlockingWriteClient, fizz::AsyncFizzBase, wangle::AsyncSocketHandler::WriteCallback, folly::WriteCallbackBase, folly::AttachDetachClient, BlockingSocket, ProxyService::ProxyHandler, folly::test::MockWriteCallback, and WriteCallback.

virtual void folly::AsyncWriter::WriteCallback::writeSuccess ( )
pure virtualnoexcept

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.
