I implemented the filtering support for iterable queries, so the old
support we dropped is back.
I also moved the newQuery(iterable<T>) from QueryBuilderFactory to
QueryBuilder (same place as the "standard" newQuery).
What is still to be done is support for ManyAssociation traversing as
in the following testcase (that is supported by RDF indexing):
QueryBuilder<Person> qb = qbf.newQueryBuilder( Person.class );
Person personTmpl = templateFor( Person.class );
Domain personInterestsTmpl = oneOf( personTmpl.interests() );
qb.where( eq( personInterestsTmpl.name(), "Cars" ) );
Query<Person> query = qb.newQuery( Network.persons() );
I will work on this by tomorrow.
