GZip


Greetings,

In an attempt to reduce the size of the files required for my application, I would like to gzip them and then unzip and read one file at a time.

Can this be done "on the fly" and then read into Plain.open() and/or VisADForm.open()?

Something like


  public static FieldImpl readGZipFile(String Filename)
  {
    FieldImpl r_field;
    visad.data.visad.VisADForm input = new visad.data.visad.VisADForm(true);

    try
    {
      r_field = (FieldImpl) input.readData(
                                             new visad.data.visad.BinaryReader(
                                             new GZIPInputStream(
                                             new FileInputStream(Filename) ) )
                                           );
    }
    catch (Exception ioe)
    { System.err.println("TerrainBlockage (readGZipFile): " + ioe); }

    return r_field;
  }


I've tried this and since readData() is "package private" it will not compile (blatantly showing my Java ignorance ;-)


Many thanks!!

-kevin.
