高速缓存算法类.英文介绍:

The Cache class implements a simple caching mechanism with "least

recently used" (LRU) replacement. It is useful for cases in which you

have some memory to spare and you wish to speed up access to frequently

used resources, of which not all will fit into available memory. Thus,

you know you have room in memory for more than 1 resource, but you don t

have room to store all possible resources in memory, so you want to

store some of them. The Cache class helps you to manage the storage in

memory of some subset of all possible resources and therefore speed up

your resource accesses. -cache algorithm category. English presentations : The Cache class implements a simple caching mec mechanism with the "least recently used" (LRU) replac ement.
