__init__ (
        self,
        name,
        doc="",
        dbname="",
        )

Intialize with information about loading the database.

dbname is the name of the database to open. This will likely be a filesystem path to a database directory.

_get_check_names (
        self,
        given_name,
        db,
        )

Get a list of all namespaces to search for the file under.

If given_name is a valid key, then it is returned as the only thing to check. Otherwise, we go forward and check all possible namespaces.

_load_database ( self,  name )

Get a connection with the given database.

_post_process ( self,  handle )

Try to parse the results of a query into a SeqRecord.

This uses Martel auto-detection to try to determine the format of a file. If the format cannot be determined, the handle itself is returned.

_rawget ( self,  params )

Do the database retrieval of the sequence, returning a handle.
