Bio::Search::DatabaseI(3) User Contributed Perl Documentation Bio::Search::DatabaseI(3)

Bio::Search::DatabaseI - Interface for a database used in a sequence search

Bio::Search::DatabaseI objects should not be instantiated since this module defines a pure interface.
Given an object that implements the Bio::Search::DatabaseI interface, you can do the following things with it:
    $name = $db->name();
    $date = $db->date();
    $num_letters = $db->letters();
    $num_entries = $db->entries();

This module defines methods for an object that provides metadata information about a database used for sequence searching.

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated.                  - General discussion  - About the mailing lists

Please direct usage questions or support issues to the mailing list:
rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution. Bug reports can be submitted via the web:
