                                                                   org.eclipse.emf.ecore.EReference reference,

```
    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
