outgoingNotification()

template<typename T>

OutgoingNotification< T > llvm::lsp::MessageHandler::outgoingNotification ( llvm::StringLiteral Method )

inline

Create an OutgoingNotification object used for the given method.

outgoingRequest()

template<typename Param, typename Result>

OutgoingRequest< Param > llvm::lsp::MessageHandler::outgoingRequest ( llvm::StringLiteral Method, OutgoingRequestCallback< Result > Callback )

inline

Create an OutgoingRequest function that, when called, sends a request with the given method via the transport.

Should the outgoing request be met with a response, the result JSON is parsed and the response callback is invoked.
