Interface CabProgressInterface

public interface CabProgressInterface
{
  // Methods
  Object progress(int progress_type, long val1, long val2, Object[]
        progress_data);
}

This interface is used by both the CabCreator and CabDecoder classes to report progress when creating or decoding a cabinet file. Currently, the only progress message supported is CAB_PROGRESS_INPUT, which is sent by CabCreator when processing input streams. For this message, progress_data[0] is a CabFileEntry object that corresponds to the file being compressed, and progress_data[1] is the position of the compressor in the input stream of that file. The application should return null in response to this message.

Return Value:
