• findEntry

  short findEntry(byte[] data,
                int offset,
                int length)

  Finds the index of an entry. If no entry found, we add it.

  Parameters:

  data - the byte array that we're looking up

  offset - Offset into data to add to Dictionary.

  length - Length beyond offset that comprises entry; must be > 0.

  Returns:

  the index of the entry, or NOT_IN_DICTIONARY if not found

  short addEntry(byte[] data,
               int offset,
               int length)

  offset - Offset into data to add to Dictionary.

  length - Length beyond offset that comprises entry; must be > 0.

  Returns:

  the index of the entry
