Outputting an EObject to a string for debugging or logging [message #504169]

I was wondering if there is a utility to output an EObject to a string that is easy to read for debugging or logging? For example, if I have an EObject of type PersonType, this toString could look something like this:

PersonType
firstName: John (String)
lastName: Smith (String)
address: (AddressType)
  streetNum: 123 (Integer)
...

Maybe the right solution is to just serialize the EObject to XML? The only trick would be to ensure that the code does not modify the EObject (if it's contained in a resource or another object). Is the best solution for this to just copy the EObject using EcoreUtil.copy() before serializing it?

Thank you!
Nikita

Nikita,

The generated toString method tries to do a reasonable job, but it needs
to be careful about printing references because that can easily lead to
circularity. You could certainly create a copy and put that in an XML
resource to serialize it that way.
