Did anyone ever implemented flyweight design pattern?

I'm curious about... :-D

Could you, please, detail your experience? For instance, what are (1) The kind of project requirements that made appealing that pattern. (2) The design issues you faced. Thank you in advance. :)

Not normally a requirements based reason. All things are (or should be) traceable back to a requirement but the flyweight pattern is mainly about optimizing memory/resource usage, which is not a requirement that a software developer should need. A generalization of a design scenario is the system will need to use the same small number of items I very large number of times, potentially infinitely. Does that help?

None. It's a very simple design, all of the best ones are.... very simple. ;)

I've never heard of it. What is it? Sounds like some kind of lightweight design approach.

...for a large numbers of objects, see, for instance http://en.wikipedia.org/wiki/Flyweight_pattern[^] :)
