So you've got an idea for a truely wicked class library
. It encapsulates
everything from an earthworm to the kitchen sink with generic behavior
s defined at all levels. But Lord, the code sure does get repetitive
after a while... How many stream
insertor / extractors are you going to have to write? If you change your base class
, how many of them are you going to have to rewrite? Soon, you're bogged down with no end of work in sight and you're considering giving up
. What would Linus do?
Well, I don't know about Linus but I do have the answer: Open C++. Imagine being able to write C++ code
that knows itself inside and out
. You could have a class rewrite itself, inserting code into the stream operators
to handle each member variable. If you make a change to a class in such a program, it will update itself at compile time
Best of all, there's a deb
package for it.
I tried it and it changed my life.
Not being a Java
junkie, I had no idea that they've been doing this for a long time. They call it introspection
. That's OK though, I still refuse to learn Java
