/** * Makes a copy of a bean. This method makes a deep copy * of the bean.The copy will have the following features. * - All beans in own-lists will be duplicated as well * - All references to shared beans will be copied but not the shared beans themselves * - All references to parent objects (_id fields) will be copied but not the parents themselves * In most cases this is the desired scenario for copying beans. * This function uses a trail-array to prevent infinite recursion, if a recursive bean is found * (i.e. one that already has been processed) the ID of the bean will be returned. * This should not happen though. * * Note: * This function does a reflectional database query so it may be slow. * * @param RedBean_OODBBean $bean bean to be copied * @param array $trail for internal usage, pass array() * @param boolean $pid for internal usage * * @return array $copiedBean the duplicated bean */ protected function duplicate($bean, $trail = array(), $pid = false) { $type = $bean->getMeta('type'); $key = $type . $bean->getID(); if (isset($trail[$key])) { return $bean; } $trail[$key] = $bean; $copy = $this->redbean->dispense($type); $copy->import($bean->getProperties()); $copy->id = 0; $tables = $this->toolbox->getWriter()->getTables(); foreach ($tables as $table) { if (strpos($table, '_') !== false || $table == $type) { continue; } $owned = 'own' . ucfirst($table); $shared = 'shared' . ucfirst($table); if ($beans = $bean->{$owned}) { $copy->{$owned} = array(); foreach ($beans as $subBean) { array_push($copy->{$owned}, $this->duplicate($subBean, $trail, $pid)); } } $copy->setMeta('sys.shadow.' . $owned, null); if ($beans = $bean->{$shared}) { $copy->{$shared} = array(); foreach ($beans as $subBean) { array_push($copy->{$shared}, $subBean); } } $copy->setMeta('sys.shadow.' . $shared, null); } if ($pid) { $copy->id = $bean->id; } return $copy; }
