Ok, I'm writing these classes and discovering more and more why I
love and hate feeds. This is nothing new to me, I've designed similar
classes in other languages before, but it's been a while.
But regardless, I have a REALbasic design question!
How should I post/handle errors? What I mean is, for example, author/
person elements require a name element in ATOM, while they require an
email address in RSS. What should happen if the developer/user tries
to create an author element in ATOM which does not contain a name?
I've though about subclassing RuntimeException and doing something
such as
raise new rssexception("Author elements must contain a name in Atom
feeds")
but this really doesn't work because it doesn't allow the developer
to catch the error without modifying the class. I could use an error
event, but I do not intend for these classes to be used that way at
all, and would be a terrible strain on the developer.
So should I use something like .LastErrorMsg and .LastErrorCode? It
seems like the best bet, but I find this method annoying to implement
and use.
Any other ideas, or should I use properties?
