[rules-users] does WorkingMemory.iterator support remove()?

[Anstis, Michael (M.)]

Wouldn't the best approach be to get the FactHandles iterator and retact
them from working memory rather than removing them through the iterator?

Iterator itr = wm.iterateFactHandles();
While(itr.next()) {
	FactHandle h = itr.next();
	wm.retract(h);
}

This would ensure truth maintenance is preserved.

Thanks - consider supporting it for efficiency. (Otherwise, removing a
set of facts from working memory requires a temporary container to
hold the facts to be removed.)
