Xtext Builder delta [message #643634]

I'm trying to figure out if Xtext Builder can be used for partial generation when saving model file. When trying the domainmodel example it looks like the delta contains more changes than I would expect.

A typical use case is to add an attribute in an entity.

	entity Foo {
		 aaa : String
	}
	
	entity Bar {
		aaa : String
		newAttr : String
	}

When adding newAttr in above sample I would like to only generate Bar, but the delta contains both Foo and Bar, both newOnes and oldOnes.

Is it possible to track changes at a more fine grained level? How would you implement the described use case in the domainmodel sample?

Hi Patrik,

you are always free to create a fine grained delta for the EObject
descriptions of a given resource description delta. That should solve
your problem, doesn't it?

Regards,
Sebastian
