About Cache Loaders A CacheLoader is an interface that specifies load() and loadAll() methods with a variety of parameters. CacheLoaders are incorporated into the core Ehcache classes and can be configured in ehcache.xml. CacheLoaders are invoked in…

About Cache Decorators Ehcache uses the Ehcache interface, of which Cache is an implementation. It is possible and encouraged to create Ehcache decorators that are backed by a Cache instance, implement Ehcache and provide extra functionality. The Dec…

About Cache Eviction Algorithms A cache eviction algorithm is a way of deciding which element to evict when the cache is full. In Ehcache , the memory store and the off-heap store might be limited in size. When these stores get full, elements are evi…

There are several common access patterns when using a cache. Ehcache supports the following patterns: Cache-aside (or direct manipulation) Cache-as-sor (a combination of read-through and write-through or write-behind patterns) Read-through Write-thro…

About CacheManager Event Listeners CacheManager event listeners allow implementers to register callback methods that will be executed when a CacheManager event occurs. CacheManager listeners implement the CacheManagerEventListener interface. The even…

About Cache Event Listeners Cache listeners allow implementers to register callback methods that will be executed when a cache event occurs. Cache listeners implement the CacheEventListener interface. The events include: An Element has been put An El…

About Exception Handlers By default, most cache operations will propagate a runtime CacheException on failure. An interceptor, using a dynamic proxy, may be configured so that a CacheExceptionHandler can be configured to intercept Exceptions. Errors…

About Cache Extensions Cache extensions are a general-purpose mechanism to allow generic extensions to a cache. Cache extensions are tied into the cache lifecycle. For that reason, this interface has the lifecycle methods. Cache extensions are create…

About Write-Through and Write-Behind Caches Write-through caching is a caching pattern where writes to the cache cause writes to an underlying resource. The cache acts as a facade to the underlying resource. With this pattern, it often makes sense to…

About Searching The Search API allows you to execute arbitrarily complex queries against caches. The development of alternative indexes on values provides the ability for data to be looked up based on multiple criteria instead of just keys. Note: Ter…
