[Geotools-gt2-users] Feature mutation

[Nguyen d. H. <Ngu...@ai...>]

Dear list

How can I add new attribute to a feature (not cloning another feature)

I understand that GT's Feature model is quite conservative about feature 
mutation. Changing attribute value is OK but not OK with adding attribute.

I am thinking of following steps:

- Make a new feture type instance with all attributes from the current 
feature's feature type instance, and a new attribute I want to add
- Create new feature with the new feature type. 
- Copy data from old feature to new feature
-...

But this way breaks my goal: I can not use referene to old feature to refer to 
the new feature (becuase they are completely different object)

Any help is appreciated
