What is object graph ?

Object-oriented applications contain complex webs of interrelated objects. Objects are linked to each other by one object either owning or containing another object or holding a reference to another object. This web of objects is called an object graph and it is the more abstract structure that can be used in discussing an application's state. - wikipedia

(JA) オブジェクト指向のアプリケーションは相互に関係のある複雑なオブジェクト網を含んでいます。オブジェクトはあるオブジェクトから所有されているか、他のオブジェクト(またはそのリファレンス)を含んでいるか、そのどちらかでお互いに接続されています。このオブジェクト網をオブジェクトグラフと呼びます。
