Member Function Documentation

Recv()

virtual void server::websocket::WebSocketConnection::Recv ( Message & message )

pure virtual

Read a message from websocket, handling pings under the hood.

Parameters

message

input message

Exceptions

engine::io::IoException

in case of socket errors

Note

Recv() is not thread-safe by itself (you may not call Recv() from multiple coroutines at once), but it is safe to call Recv() and Send() from different coroutines at once thus implementing full-duplex socket connection.

Examples

samples/websocket_service/websocket_service.cpp.

Send()

virtual void server::websocket::WebSocketConnection::Send ( const Message & message )

pure virtual

Send a message to websocket.

Parameters

message

message to send

Exceptions

engine::io::IoException

in case of socket errors

Note

Send() is not thread-safe by itself (you may not call Send() from multiple coroutines at once), but it is safe to call Recv() and Send() from different coroutines at once thus implementing full-duplex socket connection.

Examples

samples/websocket_service/websocket_service.cpp.

SendBinary()

template<typename ContiguousContainer >

void server::websocket::WebSocketConnection::SendBinary ( const ContiguousContainer & message )
