fieldsToGranule

private Granule fieldsToGranule(Fields fields)
                         throws IOException

Returns corresponding Granule of Fields.

Parameters:

fields - Fields to be converted into Granule

Throws:

IOException - if any abnormal condition occurs when converting Fields to its corresponding Granule

granuleToFields

private void granuleToFields(Granule granule,
                             Fields fields)
                      throws IOException

Fills given Fields's Field objects according to information in Granule.

Parameters:

granule - Granule containing information to fill fields

fields - Fields to be filled

Throws:

IOException - if any abnormal condition occurs when filling Fields in according to information in Granule

fillFields
