类概要

类	说明
AbstractValueAdaptingCache	Common base class for Cache implementations that need to adapt null values (and potentially other such special values) before passing them on to the underlying store.
NullValue	Simple serializable class that serves as a null replacement for cache stores which otherwise do not support null values.
SimpleValueWrapper	Straightforward implementation of Cache.ValueWrapper, simply holding the value as given at construction and returning it from SimpleValueWrapper.get().
