NAME

Bio::Index::AbstractSeq - base class for AbstractSeq

CONTENTS

SYNOPSIS



  # Make a new sequence file indexing package

  package MyShinyNewIndexer;

  use base qw(Bio::Index::AbstractSeq);

  # Now provide the necessary methods...



DESCRIPTION

Provides a common base class for multiple sequence files built using the Bio::Index::Abstract system, and provides a Bio::DB::SeqI interface.

FEEDBACK

    Mailing Lists

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.

    Support

Please direct usage questions or support issues to the mailing list:

bioperl-l@bioperl.org

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.

    Reporting Bugs

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:

    _file_format



 Title   : _file_format
 Usage   : $self->_file_format
 Function: Derived classes should override this
           method (it throws an exception here)
           to give the file format of the files used
 Example :
 Returns :
 Args    :



    fetch



  Title   : fetch
  Usage   : $index->fetch( $id )
  Function: Returns a Bio::Seq object from the index
  Example : $seq = $index->fetch( dJ67B12 )
  Returns : Bio::Seq object
  Args    : ID



    _get_SeqIO_object



  Title   : _get_SeqIO_object
  Usage   : $index->_get_SeqIO_object( $file )
  Function: Returns a Bio::SeqIO object for the file
  Example : $seq = $index->_get_SeqIO_object( 0 )
  Returns : Bio::SeqIO object
  Args    : File number (an integer)



    get_Seq_by_id



 Title   : get_Seq_by_id
 Usage   : $seq = $db->get_Seq_by_id()
 Function: retrieves a sequence object, identically to
           ->fetch, but here behaving as a Bio::DB::BioSeqI
 Returns : new Bio::Seq object
 Args    : string represents the id



    get_Seq_by_acc



 Title   : get_Seq_by_acc
 Usage   : $seq = $db->get_Seq_by_acc()
 Function: retrieves a sequence object, identically to
           ->fetch, but here behaving as a Bio::DB::BioSeqI
 Returns : new Bio::Seq object
 Args    : string represents the accession number



    get_PrimarySeq_stream



 Title   : get_PrimarySeq_stream
 Usage   : $stream = get_PrimarySeq_stream
 Function: Makes a Bio::DB::SeqStreamI compliant object
           which provides a single method, next_primary_seq
 Returns : Bio::DB::SeqStreamI
 Args    : none



    get_all_primary_ids



 Title   : get_all_primary_ids
 Usage   : @ids = $seqdb->get_all_primary_ids()
 Function: gives an array of all the primary_ids of the
           sequence objects in the database. These
           maybe ids (display style) or accession numbers
           or something else completely different - they
           *are not* meaningful outside of this database
           implementation.
 Example :
 Returns : an array of strings
 Args    : none



    get_Seq_by_primary_id



 Title   : get_Seq_by_primary_id
 Usage   : $seq = $db->get_Seq_by_primary_id($primary_id_string);
 Function: Gets a Bio::Seq object by the primary id. The primary
           id in these cases has to come from $db->get_all_primary_ids.
           There is no other way to get (or guess) the primary_ids
           in a database.

           The other possibility is to get Bio::PrimarySeqI objects
           via the get_PrimarySeq_stream and the primary_id field
           on these objects are specified as the ids to use here.
 Returns : A Bio::Seq object
 Args    : primary id (as a string)
 Throws  : "acc does not exist" exception
