NAME

Bio::EnsEMBL::DBLoader - Run time database loader

SYNOPSIS

$db =
  Bio::EnsEMBL::DBLoader->new( "Bio::EnsEMBL::DBSQL::DBAdaptor/"
    . "host=localhost;"
    . "dbname=homo_sapiens_core_19_34a;"
    . "user=ensro;" );

# $db is a database object
$db = Bio::EnsEMBL::DBLoader->standard();

# equivalent to
# Bio::EnsEMBL::DBLoader->new( $ENV{'ENSEMBL_DATABASE'} );

DESCRIPTION

This system provides a run-time loading of the database for ensembl, allowing two things

a) Only "using" the database module which is required for a
   particular implementation

b) Providing a simple string method to indicate where the database
   is, allowing per sites defaults and other things as such

The string is parsed as follows:

Before the / is the Perl database object to load, after are the parameters to pass to that database. The parameters are series of key=values separated by semi-colons. These are passed as a hash to the new method of the database object

METHODS

new

Arg [1]    : string $string
             An Ensembl database locator string.
Example    : Bio::EnsEMBL::DBSQL::DBLoader->new("Bio::EnsEMBL::DBSQL::DBAdaptor/host=localhost;dbname=homo_sapiens_core_19_34a;user=ensro;"
Description: Connects to an Ensembl database using the module specified in
             the locator string.
Returntype : The module specified in the load string is returned.
Exceptions : thrown if the specified module cannot be instantiated or the
             locator string cannot be parsed
Caller     : ?
Status     : Stable
