Hello,
this seems like an extremely trivial FAQ kind of question, yet I wasn't
able to find anything:
Given one/a set of root EObject or a Resource, how can I obtain a list
of all instances of an EClass?
I know I can use EcoreUtil.getAllProperContents() and iterate over all
objects, but I was hoping that there is a better performing way for
this. Is there perhaps a way to use any of the CrossReferencers for this?
TIA
Marius

Marius,
Nothing tracks all instances so the only way is to visit all possible
objects and filter that down to the ones you want.
