これらのネットワークの構造で構築されたネットワークがありました：

• ノード
  • ノード1
  • ノード2
• エッジ
  • エッジ1つの
  • エッジ2

エッジから、それらが接続しているノードのIDを参照するパラメータに含みます。

基本的にグラフをトラバースしたいと思います。私は最初にルートノードを見つける必要があります。これを実現させる方法は？

Answer 1

あなたは、次の操作を行うことができますいくつかのノード

で

• スタートをfromかtoとして、このノードのidを持つエッジをフィルタリングすることにより、このノードに接続されたすべてのエッジを検索します。濾過縁
• などのすべてのノード上
• ループ...
