Hopefully this isn't too dumb of a question, but I am wondering why ESRI didn't use interfaces when defining the components? Something like IMap or ILayer ITiledLayer, etc. I want something like that b/c it makes those things easier to mock in my unit tests, while allow me to code to an interface.
Now, I realize I can still mock these classes, but I have to explicitly mock them. If we had interfaces, I could use ASMock's FlexUnit 4 test runner to implicitly mock. These saves me tons of time and makes my tests less brittle.
Again, I could be missing the boat here (wouldn't be the first time) but thought I'd ask the question.
Thanks,
Glenn
