Summary
I was kind of running out of gas for the column by this time. “Objects from the Interface” is a five-paragraph description of a topic that really deserves a book, namely how to factor user interface code. However, I really wanted to present “Objects from the User's World,” and I had to pair it with something to make it long enough.
I always worry when I'm writing if what I'm doing will be long enough. Long after it was clear that the patterns book was way, way too big, I was worried if I could produce enough pages. I think this comes from early writing experiences where I had minimum word counts. I got an “F” on a paper in fourth grade for submitting a 50-word paper, 43 words of which were “very.” That should have told me something about me and about the schooling system I was experiencing.
This is the fourth and final installment in my series on where objects come from. I deliberately started with the unusual and difficult ways of finding objects. There are lots of books that will tell you how easy it is to find objects. Just underline the nouns! The fatuous phrase that keeps popping up is, “…there for the picking.” Or maybe it's “plucking.” In any case, none of the objects you'll find with “Objects from States,” “Objects from Variables,” “Objects from Collections,” or “Objects from Methods” is there for the picking.
