Interesting that someone finally put a name to something we've been
doing for decades. We used to just call it input, process, and display,
which to me seems simpler. In addition, if one used IPD, it's acronym
would at least be in the right order.
seems whenever I write something that resembles a FrontController I end up
with a process() and a display() method ... small world.
No, it's just that these organizational problems have been around
since the days of rock programming -- that's what "Design Patterns"
are, namely trying to identify, organize, and reuse code. That's
something else we've been doing for decades that has a brand new
name.
Design patterns arn't new at all! In fact the big book of Design
Patterns is was written twelve years ago!
Well, 12 years ago is new to me and there are new books being
published today. And, what I said above about "Design Patterns", is
what you said below.
see: http://en.wikipedia.org/wiki/Design_pattern_%28computer_science%29
There's a surprisingly number of old techniques that have been
given a new coat of paint and sold as the latest model. The key is
to recognize them, perhaps I should coin a new name for that, maybe
"Concept Evolution", "Process Inheritance", or "Legacy
Identification" -- but, to really get it accepted, it has to be
complicated enough to impress. :-)
Thats what Design Patterns are about. Describe abstract solutions
for object-oriented problems which dozens of programmers had already
to solve and present them in a way each programmer understands and
give them a name which everyone can understand. Its not to impress
people with complicated ideas but to simplify the communication
between programmers and give them hints how a problem could be
solved.
No, you missed my point -- many books written to simplify, don't.
That's the reason some books are better than others for different
audiences. Some books appear to have been written to impress peers
rather than to teach. If you think different, that's OK, but that
doesn't make my statement less true.
