Question

Is there an easy way to recast a parent object as a child class, preferably by a method of the parent class.

For instance I may have a “Visitor” class and “Member” class which extends “Visitor”. Upon success of the authentication method is it possible to recast the object?

Thanks

Answer 1

You can define a constructor in the Visitor class which would take another Visitor object and copy all the properties into the new object. Then this constructor will be inherited to the Member class and you will be able to create a Member object by copying an existing Visitor object.
