The attached FilterList class allows you to do what you want.
Given a heterogeneous list of B,C,D, and E, it gives a live updatable
view limited to just one type. You'd do:
List list = obj.getBorCorDorE();
List bList = new FilterList(list,B.class);
bList and list shared the underlying storage, so any change you made on
one side is going to be visible on the other side.
I have a few utility code like this, and I'm wondering where to put
them. If other people are interested in contributing those little code
pieces, maybe we should have the jaxb-utils project.
