Examples of CacheLoader

com.gemstone.gemfire.cache.CacheLoader
javax.cache.CacheLoader
Used for read-through caching and loading data into a cache.
See {@link CacheWriter} which is the corollary for load used for write-through caching. @param < K> the type of keys handled by this loader @param < V> the type of values generated by this loader @author Greg Luck @author Yannis Cosmadopoulos @since 1.0
javax.util.jcache.CacheLoader
This class loads object into the cache with the aid of the abstract load method. Should be extended by the user to implement custom loaders, such as Database queries, Directory searches, File extraction, Net searches etc. @deprecated Will be removed and replaced with an interface. @author Frank Karlstr�m
net.sf.ehcache.loader.CacheLoader
Extends JCache CacheLoader with load methods that take an argument in addition to a key @author Greg Luck @version $Id$
net.sf.jsr107cache.CacheLoader
User should implement this CacheLoader interface to provide a loader object to load the objects into cache.
org.infinispan.loader.CacheLoader
Responsible for loading cache data from an external source @author Manik Surtani @since 4.0
org.infinispan.loaders.CacheLoader
Responsible for loading cache data from an external source @author Manik Surtani @since 4.0
org.infinispan.loaders.spi.CacheLoader
Responsible for loading cache data from an external source @author Manik Surtani @author Navin Surtani @author Tristan Tarrant @since 6.0
org.infinispan.persistence.spi.CacheLoader
Defines the logic for loading data from an external storage. The writing of data is optional and coordinated through a {@link CacheWriter}. @author Mircea Markus @since 6.0
org.jboss.cache.loader.CacheLoader
A {@link org.jboss.cache.loader.CacheLoader} implementation persists and load keys to and fromsecondary storage, such as a database or filesystem. Typically, implementations store a series of keys and values (an entire {@link Map}) under a single {@link Fqn}. Loading and saving properties of an entire {@link Map} should be atomic.
Lifecycle: First an instance of the loader is created, then the configuration ( {@link #setConfig(org.jboss.cache.config.CacheLoaderConfig.IndividualCacheLoaderConfig)}) and cache ( {@link #setCache(CacheSPI)}) are set. After this, {@link #create()} is called.Then {@link #start()} is called. When re-deployed, {@link #stop()} will becalled, followed by another {@link #start()}. Finally, when shut down, {@link #destroy()} is called, after which the loader is unusable.
An {@link org.jboss.cache.loader.AbstractCacheLoader} is provided as a convenient starting placewhen implementing your own {@link org.jboss.cache.loader.CacheLoader}.
It is important to note that all implementations are thread safe, as concurrent reads and writes, potentially even to the same {@link Fqn}, are possible.
