from direct.showbase.Pool import Pool
Pool is a collection of python objects that you can checkin and checkout. This is useful for a cache of objects that are expensive to load and can be reused over and over, like splashes on cannonballs, or bulletholes on walls. The pool is unsorted. Items do not have to be unique or be the same type.
Internally the pool is implemented with 2 lists, free items and used items.
p = Pool([1, 2, 3, 4, 5]) x = p.checkout() p.checkin(x)
