2 つICENodePortCollectionのオブジェクトのArrayを戻します。最初のコレクションには、外部公開されたポートと、プロキシポートと呼ばれる関連コンパウンドノードポートの
1 つが含まれます。このコレクションは、ペアで機能します。たとえば、最初のコレクションでポジション0
にある外部に公開されたポートは、2 番目のコレクションのポジション0 にあるノードポートと一致します。
外部に公開されたポートは、コンパウンドに含まれるノードポートであり、外側のポートへの接続ポイントとして動作します。これらのポートは、ICENodeInputPortまたはICENodeOutputPortオブジェクトのいずれかになります。このプロパティおよびAddExposedParamToICECompoundNodeコマンドは、一般的に含まれるノードポートを他のグラフノードに外部公開する場合にペアで使用されます。
