Re: [Simple-support] Controlling Depth of Serialization

[Niall G. <gal...@ya...>]

Hi,

If you don't annotate the reference to C then it wont be serialized. There is another way also. If you implement a Strategy you can return a Type such that the Type.isReference == true then it wont serialize it. For instance in your strategy implementation if you return the following.

public Type setElement(....) {
   if(depth++ > 2) {
      return new EmptyType();
   }
}

To see exactly what is involved in this look at the cycle strategy. However, I think what you are looking for is a reference to C in B that is not annotated. For example


@Root
public class A {
   @Element
   private B b;
}

@Root
public class B {
   private C c;
}

public class C {
}

Here if you serialize A, only reference to b will be serialized. B's reference to C will not be serialized as it is not annotated.
