ABSTRACT
With the basic implementation behind us, we need to step up to the next level. We want to improve the implementations by making our classes more capable. With
subsref
and subsasgn
, we set up
public
as a new category of member variables. In the tailored display
function, we struggled to generate the structure-like output because a separate list of public variables is not available. In this chapter, we tailor
fieldnames
as a way to provide that list. The fieldnames
function also plugs a leak in encapsulation. The built-in version of
fieldnames
returns a list of private names, a behavior we cannot tolerate.
