Examples of ucar.grib.grib2.Grib2Input.scan()

ucar.grib.grib2.Grib2Input.scan()
scans the Grib2 file obtaining Products or Records that contain all needed information for data extraction later. For most purposes, getProductsOnly should be set to true, it's lightweight of getRecords. It is possible that one Grib record can have multiple same sections, so the previous sections don't have to be repeated in another Grib record. An example is the data section is repeated only for U and V componet of Winds in some records. @param getProductsOnly get products verse get records @param oneRecord if true then return first record @return success was the read successfull @throws NotSupportedException NotSupportedException @throws IOException on data read

    RandomAccessFile raf = new RandomAccessFile(gribFile, "r");
    raf.order(RandomAccessFile.BIG_ENDIAN);
    System.out.println("Comparing PDSs");
    Grib2Input g2i = new Grib2Input(raf);
    // params getProducts (implies  unique GDSs too), oneRecord
    g2i.scan(true, false);
    List<Grib2Product> products = g2i.getProducts();
    boolean passOne = true;
    for (int i = 0; i < products.size(); i++) {
      Grib2Product product = products.get(i);
      raf.seek(product.getPdsOffset());
