Handle Circular Hierarchies

The ObjectFiller is able to detect circulare references. You can specify that the ObjectFiller will ignore the circular references or throw an exception when a circular reference occurs. By default ObjectFiller.NET stops creating new instances in a circular reference after one loop.

In the following example the class "Parent" has a List and the class Children has a again a Parent - this is called a circular reference. The ObjectFiller.NET detects that and doesn't fill the circular object anymore! When .Setup().OnCircularReference().ThrowException(true); with the true flag is called it will raise an exception instead of just ignore the circular reference.

C#

public class Children
{
  public Parent Parent { get; set; }
}

public class Parent
{
  public List<Children> Childrens { get; set; }
}

public class HelloFiller
{
  public void FillPerson()
  {
    Filler<Parent> pFiller = new Filler<Parent>();
    pFiller.Setup()
      .OnCircularReference().ThrowException(false);

    Parent filledParent = pFiller.Create();
  }
}
