类 GenericCache

java.lang.Object
org.apache.oro.util.GenericCache
所有已实现的接口:
Serializable, Cache
直接已知子类:
CacheFIFO, CacheFIFO2, CacheLRU, CacheRandom
public abstract class GenericCache extends Object implements Cache, Serializable
This is the base class for all cache implementations provided in the org.apache.oro.util package. To derive a subclass from GenericCache only the ... methods need be overridden. Although 4 subclasses of GenericCache are provided with this package, users may not derive subclasses from this class. Rather, users should create their own implmentations of the Cache interface.
