Update a collection of EClasses that are eligible for creation of a new object in the reference.

Parameters:

owner - the proposed owner of a new reference

reference - the owner's reference in which to add a new object

eclasses - a mutable collection of classes. Implementors may add and remove elements in this collection as needed

Returns:

a mutable filtered collection of classes that can be passed into the next strategy. A suggested pattern is to modify the eclasses in place and return that collection
