示例1: RxConnection
.flatMap<RxConnection>((conn: Connection): any => {
// Disposable observable to close connection
const connectionDisposer = Rx.Disposable.create(() => conn.close().catch(err => Rx.Observable.throw(err)));
// New RxConnection stream
const sourceConnection = Rx.Observable.of(new RxConnection(conn));
// Stream of close events from connection
const closeEvents = Rx.Observable.fromEvent(conn, 'close');
// Stream of Errors from error connection event
const errorEvents = Rx.Observable.fromEvent(conn, 'error')
.flatMap((error: any) => Rx.Observable.throw(error));
// Stream of open connections, that will emit RxConnection until a close event
const connection = Rx.Observable
.merge(sourceConnection, errorEvents)
.takeUntil(closeEvents);
// Return the disposable connection resource
return Rx.Observable.using(
() => connectionDisposer,
() => connection
)
});
