IConnectionHandler

EpollSelectDispatcher alias EpollSelectDispatcher = .EpollSelectDispatcher: Local aliases to avoid public imports.
ErrorDg alias ErrorDg = void delegate(Exception exception, Event event, IConnectionHandlerInfo): Alias for an error delegate, which can be specified externally and is called when a connection error occurs.
Event alias Event = IAdvancedSelectClient.Event: Undocumented in source.
FinalizeDg alias FinalizeDg = void delegate(typeof(this) instance): Alias for a finalizer delegate, which can be specified externally and is called when the connection is shut down.

Functions

assign void assign(ISelectable listening_socket): Accepts a pending connection from listening_socket and assigns it to the socket of this instance.
connected bool connected()
error void error(Exception exception, Event event): IAdvancedSelectClient.IErrorReporter interface method. Called when a connection error occurs.
error_dg ErrorDg error_dg(ErrorDg error_dg_): Sets the error handler callback delegate which is called when a connection error occurs. Setting to null disables the error handler.
fileHandle ISelectable.Handle fileHandle()
finalize void finalize(): Must be called by the subclass when finished handling the connection. Will be automatically called by the select listener if assign() or handleConnection() throws an exception.
finalize_dg FinalizeDg finalize_dg(FinalizeDg finalize_dg_): Sets the finalizer callback delegate which is called when the connection is shut down. Setting to null disables the finalizer.
formatInfo void formatInfo(char[] buf): Formats information about the connection into the provided buffer. This method is called from the SelectListener in order to log information about the state of all connections in the pool.
handleConnection void handleConnection(): Called by the select listener right after the client connection has been assigned. If this method throws an exception, error() and finalize() will be called by the select listener.
io_error bool io_error(): Tells whether an I/O error has been reported for the socket since the last assign() call.
unregisterSocket void unregisterSocket(): Called by finalize to unregister the connection socket from epoll before closing it. This is done because closing a socket does not always mean that it is unregistered from epoll -- in situations where the process has forked, the fork's reference to the underlying kernel file description will prevent it from being unregistered until the fork exits. Therefore, to be certain that the socket will not fire again in epoll, we need to explicitly unregister it.

Variables

connection_id uint connection_id;: Instance id number in debug builds.
object_pool_index size_t object_pool_index;: Object pool index.
socket ISocket socket;: Client connection socket, exposed to subclasses downcast to Conduit.
socket_error SocketError socket_error;: SocketError instance to throw on error and query the current socket error status.
