Ace::Object 1.89

Details

Ace::Object 1.89 is libraries software developed by Lincoln Stein.
Ace::Object is a Perl module to manipulate Ace Data Objects.



SYNOPSIS

open database connection and get an object
use Ace;
$db = Ace->connect(-host => 'beta.crbm.cnrs-mop.fr',
-port => 20000100);
$sequence = $db->fetch(Sequence => 'D12345');

Inspect the object
$r = $sequence->at('Visible.Overlap_Right');
@row = $sequence->row;
@col = $sequence->col;
@tags = $sequence->tags;

Explore object substructure
@more_tags = $sequence->at('Visible')->tags;
@col = $sequence->at("Visible.$more_tags[1]")->col;

Follow a pointer into database
$r = $sequence->at('Visible.Overlap_Right')->fetch;
$next = $r->at('Visible.Overlap_left')->fetch;

Classy way to do the same thing
$r = $sequence->Overlap_right;
$next = $sequence->Overlap_left;

Pretty-print object
print $sequence->asString;
print $sequence->asTabs;
print $sequence->asHTML;

Update object
$sequence->replace('Visible.Overlap_Right',$r,'M55555');
$sequence->add('Visible.Homology','GR91198');
$sequence->delete('Source.Clone','MBR122');
$sequence->commit();

Rollback changes
$sequence->rollback()

Get errors
print $sequence->error;

Ace::Object is the base class for objects returned from ACEDB databases. Currently there is only one type of Ace::Object, but this may change in the future to support more interesting object-specific behaviors.

Using the Ace::Object interface, you can explore the internal structure of an Ace::Object, retrieve its content, and convert it into various types of text representation. You can also fetch a representation of any object as a GIF image.

If you have write access to the databases, add new data to an object, replace existing data, or kill it entirely. You can also create a new object de novo and write it into the database.

Requirements:
Perl
Ace::Object 1.89 supports english interface languages and works with Linux.

Downloading Ace::Object 1.89 will take several seconds if you use fast ADSL connection.
