Re: Handling Iterators in JXTG

Am I wrong or there is no way to handle iterators in JXTG? One can use forEach
for collections but I sometimes would like to pass and iterator to a view to
process larger result sets.
In Hibernate you can:

var list = session.createQuery("from LargeTable").list() which creates a whole
collection at once but you can also do:
var iterator = session.createQuery("from LargeTable").iterate() which makes
generating view much less memory consuming.
Maybe something like:
<jx:while test="${it.hasNext()}">
        <jx:set car="current" value=${it.next()}/>
        ${current.value}<br/>
</jx:while>
The syntax is ugly I know but after a little tuning it would be very useful.

<jx:forEach> should work on Iterators (as well Enumerations):

sendPage("page.html", {iteration: session.createQuery("from 
LargeTable").iterate()});

<jx:forEach var="current" items="${iteration}">
    ${current.value}</br>
</jx:forEach>
