[Pharo-users] Multiple sorting helper

[Esteban A. Maringolo]

Hi,

I have a collection of objects and I want to sort its contents by more
than one attribute (including nil values), and I thought somebody
might have already done this.

Something like:

sorter := MultipleSortCriteria new
               add: #lastName;
               add: [:each | each personalInfo age ] ascending: false.
aCollection asSortedCollection: sorter.

Is there a package with utility classes for this?

Thank you!
