Copying EObjects with readonly properties [message #419775]

Hi,

I want to create a deep copy. Currently I am using EcoreUtil.copy.
Unfortuantely, properties that are not changeable are not copied. The only
way I see is making the properties changeable and document the setters not
to use them.

Is there any other way?
The problem is similar to deserialization. This state can be recognized in
the setter, so that an exception can be thrown while the resource is not
loaded. What about copiying?

Kind regards, Sebastian

Sebastian,

How about just suppressing the setters from the API to make it more
difficult to change them accidentally? You can do that with an
annotation as created by EcoreUtil.setSuppressedVisibility.
