CMPISample という名前のサンプル HCM プラグインから疑似コードを提供しています。このサンプルの目的は、CMInterface と、プラグインで提供する必要のある 機能の一部のインプリメンテーションをデモンストレーションすることです。CMPISample は、ユーザーが指定したデータベースからホスト信任状を読み取るように設計されています。
|
この機能には、可能な場合には常に提供された CMPIVault クラスを使用することをお勧めします。Z and I Emulator for Web に用意されているプラグインがいずれもニーズに応じていない場合にのみ、CMPISample のようなカスタム・プラグインを作成する必要があります。 |
