  • Method Details

    • connect

      public String connect() throws org.eclipse.january.DatasetException
      Connect to an existing dataset.
      Callers should use isConfigCompatible(CameraConfiguration, StreamType) to check that the wrapped stream is compatible before calling this function.
      Specified by:
      connect in interface org.eclipse.january.dataset.IDatasetConnector
      Throws:
      org.eclipse.january.DatasetException

    • disconnect

      public void disconnect()
      Specified by:
      disconnect in interface org.eclipse.january.dataset.IDatasetConnector

    • isConfigCompatible

      public boolean isConfigCompatible(CameraConfiguration cameraConfig, StreamType streamType)
      Check that the given CameraConfiguration invalid input: '&' StreamType are compatible with the values used to create this wrapper.

      We check the parameters that are used to create the stream, not the ones that are GUI-related.
