Hi!
While discussing with Reinhard we came over an interesting use case:
public class Person {
private String name;
private Person marriedTo;
}
Person reinhard = new Person("reinhard");
Person anna = new Person("anna");
reinhard.setMarriedTo(anna);
anna.serMarriedTo(reinhard);
String json = Mapper.writeObjectAsString(reinhard);
Currently this sample would lead to an endless loop, right?
BUT, we can do something against it: We keep a Map<Object, Integer>. For each
object written we increment the number;
IF an object was already written before (comparison using == and not equals()!)
then we write a 'placeholder'
{"name":"reinhard","marriedTo":{"name":"anna","marriedTo":"1"}}
Not sure if we can use a simple number or whether we need to use a placeholder
object with e.g. "//javaType".
But you get the idea I hope.
Any thoughts?
