问题 I'm triying to understand method references and I don't know how with this "Book[]::new" it can create an array with the right number of elements. Book[] arrayBook = stBooks.toArray(Book[]::new); In order to create the array when I use the second and third option I have to specify a Functional Interface that Receive an Int and return a new Array. But, in the first option I don't know where is the implementation and where you specify the number or elements that is going to have the array. I

问题 My app is basically a phone call over MultipeerConnectivity. Here is how I'm setting up the audio session: Note that recordingSession is of type AVAudioSession and captureSession is of type AVCaptureSession. func setupAVRecorder() { print("\(#file) > \(#function) > Entry") do { try recordingSession.setCategory(AVAudioSessionCategoryPlayAndRecord) try recordingSession.setMode(AVAudioSessionModeVoiceChat) try recordingSession.setPreferredSampleRate(44100.00) try recordingSession

问题 We got one or two CheckPoint Failure during processing data every day. The data volume is low, like under 10k, and our interval setting is '2 minutes'. (The reason for processing very slow is we need to sink the data to another API endpoint which take some time to process at the end of flink job, so the time is Streaming data + Sink to external API endpoint). The root issue is: Checkpoints time out after 10 mins, this caused by the data processing time longer than 10 mins, so the checkpoint

问题 I need to make a HTTP GET request to foreign server to start receiving events. After request I immediately get multipart/x-mixed-replace response. When an event occurs, it's sent as XML message together with boundary indicating the end of this part. Now I must implement it in Node.js. With normal request I use node-rest-client , call its get() method and put my logic in method's callback. Trouble is that callback is executed only when response is finished and with multipart/x-mixed-replace it

问题 I´m new in the bloc pattern and stream stuff. I want to show up an alert dialog when I press a button, but I can´t find a way to do it. Actually my code is: Widget button() { return RaisedButton( child: Text('Show alert'), color: Colors.blue[700], textColor: Colors.white, onPressed: () { bloc.submit(); }); } return Scaffold( appBar: AppBar( title: Text("Title"), ), body: StreamBuilder( stream: bloc.getAlert, builder: (context, snapshot) { if (snapshot.hasData) { return Text("I have Dataaaaaa

问题 I am not being able to pipe the output of the ffmpeg over a stdout.
