Examples of org.jasig.portal.utils.cache.CacheKey

org.jasig.portal.utils.cache.CacheKey
A object designed for use as a cache key. It assumes that all key values are immutable and pre-computes the hashCode.
Tags can be added to a key which are used with the {@link TaggedCacheEntry} facilities. These tags ARE NOT includedin CacheKey comparison. @author Eric Dalquist
