How to get the whole set of containers [message #971059]

I'd like to get the whole set of containers for an object.
i.e. {self.oclContainer(); self.oclContainer().oclContainer(); self.oclContainer().oclContainer().oclContainer(); etc.}

What is the right way to do that?

Thank you

Regards

HI

Have you looked at the closure() iteration?

I actually tried this self->closure(oclContainer()) but it says Closure body type 'OclElement' does not conform to iterator type

Ok for those who may have the same question the answer is

self.oclAsType(OclElement)->closure(oclContainer())

Hi

Good workaround. I don't think you should need it though.

Thanks Ed,
just to provide a complete answer, in case you need to use that in a complete ocl file the ocl namespace is needed

self.oclAsType(ocl::OclElement)->closure(oclContainer())

Ed it seems that when using Complete OCL to validate an XText language as you explained in http://www.slideshare.net/EdWillink/, if I create a <<definition>> Constraint (i.e. def:) initialized with an attribute retrieved after a closure (eventually filtered to just get one object) I get strange errors in the XText editor.
