Hi Jakob,
I think the NOT flag would be perfectly OK, and get around the problem of 'not'
being a unary operator and therefore messing up the existing binary stuff.

commented with your new suggestion.
Thanks,
Rob :)

hi antonio,
the class is only required to avoid a NullPointerException and it must
be defined in the repository. the class does not affect the SQL. i admit
using an arbitrary class is not very elegant (i'd prefer passing null),
but today it's the only solution.
