Design patterns in the real world: Flyweight

Quite some software engineers think that design patterns are some overly complicated, mythical, abstract things that bring no practical value to software development. This is unfortunate. In order to prove they are indeed something real, in this (and some upcoming) post(s) we are going to take a look on a few examples on how real software products implement some of the GoF design patterns. The first one to be examined is Flyweight.

Perhaps uncomfortable is not the right word here; the whole situation is a huge paradox: objects that fail to behave in an object-oriented way. Of course I’m talking about classes like Tuple and Triplet (or whatever name they may have in different libraries). Continue reading “Non object-oriented objects”
