example for flyweight pattern

hey all,

imagine the following:

a screen full of circles. each circle has coordinates and a style. the
coordinates are always different, a style can be the same among 0 to
many circles.

what would be the correct implementateion of the flyweight pattern?

a) one (circle-)object for every different style, and the coordinates
for all circles stored in the context.
b) one circle-object for every different set of coordinates and the
styles stored in the context.

and in general: how would you solve this issue most memory efficient,
if not by one of the two answers above (imagine billions of circles
and tenthousands of styles)?

thanks

Ok, I've been staring at this and figuring it out for a while. I'm close to getting it, but I'm confused by the examples: (?(id/name)yes-pattern|no-pattern) Will try to match with yes-pattern if the group with given id or name exists, and with no-pattern if it doesn't. |no-pattern is optional and can be omitted. For example,...
