Below, again, we get yourself a Useful resource object, we get its map of designs, and we do a little something With all the map. But in advance of saving the map back on the pool of objects, it can be cleared after which populated with corrupted data, building the Useful resource object unsuitable for reuse. Among the list of most important details of an object pool is the fact that when an object is returned, it need to restore to a state suited to further reuse.
