Bio::DB::LocationI - A RandomAccessI-like abstract interface for retrieving location data from a sequence database and returning Bio::LocationI objects

SYNOPSIS

Top

  #
  # get a database object somehow using a concrete class
  #

  $loc = $db->get_Location_by_id('123456');

  #
  # $loc is a Bio::LocationI object
  #

DESCRIPTION

Top

This is a pure interface class - in other words, all this does is define methods which other (concrete) classes will actually implement.

The Bio::DB::LocationI class defines methods used to retrieve location data from a sequence. This is returned in the form of Bio::LocationI objects, which can include:

Bio::Location::Simple Bio::Location::Fuzzy Bio::Location::Split

At the moment it is just the ability to make Bio::LocationI objects from a name or unique id (id), an accession number (acc), and so on.

Ewan Birney originally wrote Bio::DB::RandomAccessI, from which this class is based.

APPENDIX

Top

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

get_Location_by_id

 Title   : get_Location_by_id
 Usage   : $loc = $db->get_Location_by_id('123456')
 Function: Gets a Bio::LocationI-implementing object by its name (id)
 Returns : a Bio::LocationI object or undef if not found
 Args    : the id (as a string) of a sequence

get_Location_by_acc

 Title   : get_Location_by_acc
 Usage   : $loc = $db->get_Location_by_acc('X77802');
 Function: Gets a Bio::LocationI object by accession number
 Returns : A Bio::LocationI object or undef if not found
 Args    : accession number (as a string)
 Throws  : "more than one sequences correspond to this accession"
            if the accession maps to multiple primary ids and
            method is called in a scalar context

get_Location_by_version

 Title   : get_Location_by_version
 Usage   : $loc = $db->get_Location_by_version('X77802.1');
 Function: Gets a Bio::LocationI object by sequence version
 Returns : A Bio::LocationI object
 Args    : accession.version (as a string)
 Throws  : "acc.version does not exist" exception
