+ tok_get_all
+ public instance (\@) tok_get (@ $tokens)
+
+ Description: This method retrieves the specified tokens ($tokens) from
+ storage and returns an array ref of arrays spam count, ham acount and
+ last access time.
+
+ nspam_nham_change
+ public instance (Boolean) nspam_nham_change (Integer $num_spam, Integer

+ Description: This method does a mass update of the given list of tokens
+ $tokens, if the existing token atime is < $atime.
+
+ The assumption is that the tokens already exist in the database.
+
+ We should never be touching more than N_SIGNIFICANT_TOKENS, so we can

+ the next operation.
+
+ clear_database
+ public instance (Boolean) clear_database ()

+ private instance (Boolean) _connect_db ()
+
+ Description: This method connects to the SQL database.
+
+ _put_token
+ private instance (Boolean) _put_token (string $token, integer
+ $spam_count, integer $ham_count, string $atime)
+
+ Description: This method performs the work of either inserting or
+ updating a token in the database.

+ to use in queries.
+
+ tie_db_readonly
+ public instance (Boolean) tie_db_readonly ();

+ properly setup and working. If necessary it will initialize a user's
+ bayes variables so that they can begin using the database immediately.
+
+ tie_db_writable
+ public instance (Boolean) tie_db_writable ()

+
+ calculate_expire_delta
+ public instance (%) calculate_expire_delta (Integer $newest_atime,
