Carlo, Andy,
I like the Iterator<> interfaces in the Jena framework for getting
data out, but I make a habit of always putting results in a List or
Queue or something before putting them back into the same Jena model
because i get less BS per mile that way in terms of Exceptions and
other exceptional events.
Does Jena have an official policy on being reenterable in that way?
Paul - iterators are "normal". Many do not support .remove
Like any Java iterators - do not modify the underlying data structure
while iterating. CCE will result - or wrong answers.
Either copy to a list, or note work to be done and do after the iterator
is no longer needed. Standard java idioms. List<> is good if you can
afford the space.
Beware that ArrayList<> has peculiar growth characteristics for large sizes.
See Iter - like Java8 Stream but for iterators.
