# get a database object somehow using a concrete class
$loc = $db->get_Location_by_id('123456');
# $loc is a Bio::LocationI object
DESCRIPTIONThis 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.
CONTACTEwan Birney originally wrote Bio::DB::RandomAccessI, from which this class is based.

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