Class Recorder

java.lang.Object
org.openpatch.scratch.extensions.recorder.Recorder
Direct Known Subclasses:
FFmpegRecorder, FrameRecorder, GifRecorder
public abstract class Recorder extends Object
The Recorder class provides a framework for recording frames to a file. It includes methods to start and stop the recording process, and an abstract method saveFrame() that must be implemented by subclasses to define the specific behavior for saving a frame.

This class is intended to be extended by other classes that provide concrete implementations for saving frames in different formats.

Example usage: 


 public class MyRecorder extends Recorder {
     public MyRecorder(String path, String ext) {
         super(path, ext);
     }

     @Override
     public void saveFrame() {
         // Implementation for saving a frame
     }
 }

Note: The Recorder class uses the Applet class to register a method that is called after each frame is drawn. This ensures that frames are saved at the appropriate time during the recording process.
