Hi, my question is:
Is there some reason not to store all field attributes in one place (*.fnm) ? A lucene field has some attributes: private boolean storeTermVector = false; private boolean storeOffsetWithTermVector = false; private boolean storePositionWithTermVector = false; private boolean omitNorms = false; private boolean isStored = false; private boolean isIndexed = true; private boolean isTokenized = true; private boolean isBinary = false; private boolean isCompressed = false; Some of them are stored as a one byte-bit mask in the field infos file (*.fnm), isIndexed (IS_INDEXED) storeTermVector (STORE_TERMVECTOR) storePositionsWithTermVector (STORE_POSITIONS_WITH_TERMVECTOR) storeOffsetWithTermVector (STORE_OFFSET_WITH_TERMVECTOR) omitNorms (OMIT_NORMS) Other attributes are stored as a bit mask in the data file (*.fdt): tokenized binary compressed They could be stored as a bit field of variable length (like vint). Then you would have all pieces of information about fields in one place: binary format -> *.fnm java object -> FieldInfo read/write -> FieldInfos bit mask definitions -> Field or FieldInfo The nine booleans in Field could be replaced by a bit mask (int). Using storage of attributes as a bitmask of variable length in *.fnm would not break binary format if more attributes come up in future. I feel like it would make the code clearer and easier to understand. Any comments?
