Hello

I am using in my query sortBy operation but as a result I am getting exception.
Can you please provide some example for sortBy operation

domain::Operation.allInstances()->select(r|r.oclAsType(domain::Operation).uid ='423894789').oclAsType(domain::Operation).parameters->sortBy(r|r.oclAsType(domain::Parameter).order)

Thanks
Arserniy Isakov

Hi Arseniy,

Sure. sortBy returns a copy of the collection on which it is invoked, sorted by the result of the provided expression. For example, the following expression would return a name-sorted collection of all EClasses in an Ecore model: EClass.all.sortBy(c | c.name). I hope this helps.

Cheers,
Dimitris
