Title: 静的に型付けされたクラスベースのオブジェクト指向ソフトウェアのノンブロッキング動的更新の方法、コンピュータ・プログラム製品、およびシステム
IPC: G06F11/00
Filed: 2010-11-16
Abstract: 本発明の下で、アクティブに動作するコンピュータ・システム内の仮想マシン上でバイトコードとして実行する静的に型付けされたクラスベースのオブジェクト指向ソフトウェアのノンブロッキング動的更新の方法、コンピュータ・プログラム製品、およびシステムが提供される。既存の１つまたは複数のモジュール（バイトコード表現の形でのアプリケーション・リソースおよびクラス定義の識別可能なコレクション）からインスタンス化されたオブジェクトのセットは、アクティブに動作するコンピュータ・システム内の仮想マシン上での実行の準備ができている。アクティブに動作する仮想マシンに既にロードされたモジュールに対応する１つまたは複数のモジュールの新しいバージョンが、動作中のソフトウェアを更新するために仮想マシンに動的にロードされる。ロードされたモジュール内のクラス定義は、あるクラスの以前のバージョンのオブジェクトと新しいバージョンのオブジェクトとの間の透過的状態転送および共有されるオブジェクト・アイデンティティを可能にするバイトコードを挿入することによって、動的更新のために準備される。ソフトウェア更新の場合に、更新されるクラスの以前のバージョンからインスタンス化されたオブジェクトは、その将来の対応するオブジェクトへリダイレクトする潜在能力を有する未初期化サロゲートオブジェクトになる。対応するオブジェクトは、宣言するクラス・メンバの最初のアクセス時にレイジイに作成される。オブジェクトおよびクラスの挙動のレイジイ・リダイレクションに加えて、ノンブロッキング動的更新が、レイジイ移植によって達成される。
