56 Text::Tradition::Directory is an interface for storing and retrieving text traditions and all their data, including an associated stemma hypothesis. It is an instantiation of a KiokuDB::Model, storing traditions and associated stemmas by UUID.
62 Constant for the minimum password length when validating passwords,
67 has MIN_PASS_LEN => ( is => 'ro', isa => 'Num', default => sub { 8 } );
73 Returns a Directory object.
77 Returns a hashref mapping of ID => name for all traditions in the directory.
79 =head2 tradition( $id )
81 Returns the Text::Tradition object of the given ID.
83 =head2 save( $tradition )
85 Writes the given tradition to the database, returning its ID.
87 =head2 delete( $tradition )
89 Deletes the given tradition object from the database.
90 WARNING!! Garbage collection does not yet work. Use this sparingly.
