RelationshipQuery

[do...@xsinet.co.za]

Hi

1.  I have an ObjEntity with a relationship that returns a Map, which I
need to refetch.

public Map<String, ActivityResult> getResults() {
    return (Map<String, ActivityResult>)readProperty(RESULTS_PROPERTY);
}

How do I go about it ?


2.  With a regular relationship that returns a list I used
RelationshipQuery like so:

public List<PatientAllergy> getAllergies()
{
	RelationshipQuery  refreshAlrgy = new RelationshipQuery
	(
		getObjectId(), ALLERGIES_PROPERTY
	);
	return getObjectContext().performQuery( refreshAlrgy );
}

I didn't want any caching on this relationship, hence the above. Not sure
if its the right way of doing this though.

Anyway with reference to question 1. performQuery returns a list, but I
need the Map  ?

Thanks.

1. Open cayenne modeler

2. Choose the Java entity you want

3. Go to "relationships" and click on the relationship you want to model

4. Click the little "I" in the toolbar at the top

5. In the ObjRelationship inspector now open, change the collection type to List, Collection, Map, or Set.
