Design Patterns Implementation

1. Singleton Pattern

// Ensures single instance of core classes
class Google_Drive extends Base {
    use Singleton;

    public static function instance() {
        return parent::get_instance();
    }
}

2. Factory Pattern

// Dynamic class instantiation based on context
class Endpoint_Factory {
    public static function create($endpoint_type) {
        switch($endpoint_type) {
            case 'drive': return new Drive_API();
            case 'posts': return new Posts_API();
        }
    }
}

3. Observer Pattern

// WordPress hooks and filters implementation
add_action('wp_ajax_drive_upload', array($this, 'handle_upload'));
add_filter('posts_maintenance_scan', array($this, 'modify_scan'));

4. Strategy Pattern

// Different processing modes and output formats
class Processing_Strategy {
    public function execute($mode = 'foreground') {
        return $mode === 'background' 
            ? $this->background_process()
            : $this->foreground_process();
    }
}
