このコンテナのすべてのノードを含むICENodeCollectionを戻します。これにはICENodeとイミディエイトICECompoundNodeオブジェクトの両方が含まれます。ICECompoundNode
オブジェクトの内側のノードにアクセスするには、ICENodeContainer.CompoundNodesを使用して対応する
ICECompoundNode親のこのプロパティを呼び出す必要があります。
このプロパティは通常、ノードグラフ全体にわたって反復処理するために使用されます。たとえば、ICETree上のこのプロパティを呼び出すことで開始します。戻されたコレクションにわたって反復処理するときにコンパウンドノードが見つかった場合は、そのコンパウンドのICENodeContainer.CompoundNodesを呼び出して、内側のコンパウンドノードを取得し、さらにグラフ深くまで再帰的に処理します。
