Is it possible to get the distinct elements of a set?
Suppose I need to include the header files of the types of my classifiers' properties. I'd like to include each header file once though there are more than one property with that type.

Hi

All elements of a Set are inherently distinct.

If you want a different distinction criterion perhaps you want
->isUnique(...) or just a Set of your alterante view.

Hi Andrea,

To complete Ed's answer, if you have a collection which is not unique and need all distinct entries it contain, convert it to a set :

[collection->asSet()/]

or if you need the order to be constant

[collection->asOrderedSet()/]
