Some great ideas there! You are certainly correct, I could well add a
bit more explanation to my examples. I generally start out with good
intentions, but I try to do an example all in one day when I can, with
the verbiage coming last. As a result by the time I do the verbiage
I'm not as enthusiastic as I was at the start. And - as is apparent
from my title for this thread - The Adapter Pattern instead of the
Bridge Pattern - perhaps getting a bit sloppy. It would probably a
good idea to go over all of my examples when I'm done the set, take a
fresh look, and add a bit more text.
I'd also like to add UML, but I haven't found a UML generator for PHP
that would create jpgs. And which is free.
