The registry is an object storage container strictly used to store object instances and access them by reference. It does not allow registered objects to be overwritten unless manually specified to do so.
Objects can be added to the registry using Registry::set().
use OSC\OM\Db;
use OSC\OM\Registry;
$OSCOM_Db = Db::initialize();
Registry::set('Db', $OSCOM_Db);

Parameter | Value |
---|---|
$key | The name of the object to reference in the registry. |
$value | The object to store in the registry. |
$force | If this is enabled, overwrite an existing object with a new value. Default: false |
An object can be accessed in the registry using Registry::get().
use OSC\OM\Registry;
$OSCOM_Db = Registry::get('Db');
Parameters
Registry::get($key)
Parameter | Value |

use OSC\OM\Db;
use OSC\OM\Registry;
if (Registry::exists('Db')) {
$OSCOM_Db = Registry::get('Db');
} else {
$OSCOM_Db = Db::initialize();
Registry::set('Db', $OSCOM_Db);
