NAME

Bio::Index::SwissPfam - Interface for indexing swisspfam files

SYNOPSIS

    use Bio::Index::SwissPfam;
    use strict;

    my $Index_File_Name = shift;
    my $inx = Bio::Index::SwissPfam->new('-filename' => $Index_File_Name, 
                                                                 '-write_flag' => 'WRITE');
    $inx->make_index(@ARGV);

    use Bio::Index::SwissPfam;
    use strict;

    my $Index_File_Name = shift;
    my $inx = Bio::Index::SwissPfam->new('-filename' => $Index_File_Name);

    foreach my $id (@ARGV) {
        my $seq = $inx->fetch($id); # Returns stream
             while( <$seq> ) {
                 if(/^>/) {
                       print;
                          last;
                 }
             }
    }

DESCRIPTION

SwissPfam is one of the flat files released with Pfam. This modules provides a way of indexing this module.

Inherits functions for managing dbm files from Bio::Index::Abstract.pm, and provides the basic funtionallity for indexing SwissPfam files. Only retrieves FileStreams at the moment. Once we have something better (ie, an object!), will use that. Heavily snaffled from Index::Fasta system of James Gilbert. Note: for best results 'use strict'.
