Examples of org.apache.shiro.cache.CacheManager

org.apache.shiro.cache.CacheManager
A CacheManager provides and maintains the lifecycles of {@link Cache Cache} instances.
Shiro doesn't implement a full Cache mechanism itself, since that is outside the core competency of a Security framework. Instead, this interface provides an abstraction (wrapper) API on top of an underlying cache framework's main Manager component (e.g. JCache, Ehcache, JCS, OSCache, JBossCache, TerraCotta, Coherence, GigaSpaces, etc, etc), allowing a Shiro user to configure any cache mechanism they choose. @author Les Hazlewood @since 0.9
