NAME

       Bio::Index::Swissprot - Interface for indexing one or more Swissprot files.

SYNOPSIS

	 # Make an index for one or more Swissprot files:

	   use Bio::Index::Swissprot;
	   use strict;

	   my $index_file_name = shift;
	   my $inx = Bio::Index::Swissprot->new(
	       -filename => $index_file_name,
	       -write_flag => 1);
	   $inx->make_index(@ARGV);

	 # Print out several sequences present in the index in Genbank
	 # format:

	   use Bio::Index::Swissprot;
	   use Bio::SeqIO;
	   use strict;

	   my $out = Bio::SeqIO->new( -format => 'genbank',
				      -fh => *STDOUT );
	   my $index_file_name = shift;
	   my $inx = Bio::Index::Swissprot->new(-filename => $index_file_name);

	   foreach my $id (@ARGV) {
	       my $seq = $inx->fetch($id); # Returns a Bio::Seq object
	       $out->write_seq($seq);
	   }

	   # alternatively
	   my ($id, $acc);
	   my $seq1 = $inx->get_Seq_by_id($id);
	   my $seq2 = $inx->get_Seq_by_acc($acc);

DESCRIPTION

       By default the index that is created uses the AC and ID identifiers as keys. This module inherits functions for managing dbm files from
       Bio::Index::Abstract.pm, and provides the basic functionality for indexing Swissprot files and retrieving Sequence objects from them. For
       best results 'use strict'.

       You can also set or customize the unique key used to retrieve by writing your own function and calling the id_parser() method.  For
       example:

	  $inx->id_parser(&get_id);
	  # make the index
	  $inx->make_index($index_file_name);

	  # here is where the retrieval key is specified
	  sub get_id {
	     my $line = shift;
	     $line =~ /^KWs+([A-Z]+)/i;
	     $1;
	  }

APPENDIX

       The rest of the documentation details each of the object methods.  Internal methods are usually preceded with a _

   _index_file
	 Title	 : _index_file
	 Usage	 : $index->_index_file( $file_name, $i )
	 Function: Specialist function to index Swissprot format files.
		   Is provided with a filename and an integer
		   by make_index in its SUPER class.
	 Example :
	 Returns :
	 Args	 :

   id_parser
	 Title	 : id_parser
	 Usage	 : $index->id_parser( CODE )
	 Function: Stores or returns the code used by record_id to
		   parse the ID for record from a string.
		   Returns &default_id_parser (see below) if not
		   set. An entry will be added to
		   the index for each string in the list returned.
	 Example : $index->id_parser( &my_id_parser )
	 Returns : ref to CODE if called without arguments
	 Args	 : CODE

   default_id_parser
	 Title	 : default_id_parser
	 Usage	 : $id = default_id_parser( $line )
	 Function: The default parser for Swissprot.pm
		   Returns $1 from applying the regexp /^IDs*(S+)/
		   or /^ACs+([A-Z0-9]+)/ to the current line.
	 Returns : ID string
	 Args	 : a line string

   _file_format
