3.3. Composition of a `Configuration` Object

A Configuration is composed of a number of subobjects:

Following is a brief overview of the components of a Configuration . See the javadoc and the linked chapters in this book for a more complete explanation of the configurations associated with each component.

Configuration : top level object in the hierarchy; exposes the configuration properties listed in the configuration reference section of this book.
BuddyReplicationConfig : only relevant if buddy replication is used. General buddy replication configuration options. Must include a:
BuddyLocatorConfig : implementation-specific configuration object for the BuddyLocator implementation being used. What configuration elements are exposed depends on the needs of the BuddyLocator implementation.
EvictionConfig : only relevant if eviction is used. General eviction configuration options. Must include at least one:
EvictionRegionConfig : one for each eviction region; names the region, etc. Must include a:
EvictionPolicyConfig : implementation-specific configuration object for the EvictionPolicy implementation being used. What configuration elements are exposed depends on the needs of the EvictionPolicy implementation.
CacheLoaderConfig : only relevant if a cache loader is used. General cache loader configuration options. Must include at least one:
IndividualCacheLoaderConfig : implementation-specific configuration object for the CacheLoader implementation being used. What configuration elements are exposed depends on the needs of the CacheLoader implementation.
RuntimeConfig : exposes to cache clients certain information about the cache's runtime environment (e.g. membership in buddy replication groups if buddy replication is used.) Also allows direct injection into the cache of needed external services like a JTA TransactionManager or a JGroups ChannelFactory .
