c# - 是否可以在 Jint 中克隆或保存/恢复引擎状态？

Question

我有相对较长的初始代码，然后我使用引擎执行可能影响引擎状态的单个语句。我想通过不一直重新执行初始代码来加快速度。

是否有可能：

• 快速克隆具有整个状态的引擎实例或

• 快速保存和恢复引擎状态？

  private void RunScript()
  {
      var engine = new Engine();
  
      //Please note I am executing this only once:
      engine.Execute(@"
          var globalCounter = 0;
          var increaseCounter = function() { globalCounter++; return globalCounter; };
          ");
  
      //What I need:
      //engine.MagicallySaveState();
  
      var result1 = engine.Execute("increaseCounter()").GetCompletionValue().AsNumber();
      //result1==1
  
      //What I need:
      //engine.MagicallyRestoreState();
  
      var result2 = engine.Execute("increaseCounter()").GetCompletionValue().AsNumber();
      //result2 should be still 1 and not 2 if Save/Restore works;
  
  }
