Entity Modeler has an EOQualifier format parser in it (that is not
currently the one being used), and Cayenne has its expression parser.
Both of these are open-source and could be easily adapted. In Entity
Modeler, look in org.objectstyle.eomodeler.model.qualifiers.

I am thinking of implementing qualifier creating GUI bindings into

creation of complex qualifiers that are based on many fields.
I have the binding part figured out, what I still need is a way to
define how individual qualifications combine into a single
qualifier (AND, OR, NOT, etc). So, assuming that I have all the
qualification keys and values at hand, how can I easily define
their structure? I've thought of making a String parsing mechanism,
but that is more work then I can afford at the moment. Does someone
have this already?
Yes I've recently built a parsing mechanism that's quite flexible.
Contact me off list.
Btw, ideally it would be EOF agnostic. What I would do is define a
general Qualifier class GUI binding mechanisms, and then provide a
translator class that would create EOF qualifiers from that.
Yep.
