Constructor & Destructor Documentation
| BrassSpellingTable::BrassSpellingTable | ( | const std::string & | dbdir, | |
| bool | readonly | |||
| ) | [inline] |
Create a new BrassSpellingTable object.
This method does not create or open the table on disk - you must call the create() or open() methods respectively!
- Parameters:
-
dbdir The directory the brass database is stored in. readonly true if we're opening read-only, else false.

Member Data Documentation
std::map<Brass::fragment, std::set<std::string> > BrassSpellingTable::termlist_deltas [private] |
Changes to make to the termlists.
This list is essentially xor-ed with the list on disk, so an entry here either means a new entry needs to be added on disk, or an existing entry on disk needs to be removed. We do it this way so we don't need to store an additional add/remove flag for every word.
