3.3. Composition of a Configuration Object

Configuration : top level object in the hierarchy; exposes the configuration properties listed in the Section 12.2, “Configuration File Quick Reference” section of this book.

BuddyReplicationConfig : only relevant if Section 8.1.2.2, “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 Chapter 10, 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:

EvictionAlgorithmConfig : implementation-specific configuration object for the EvictionAlgorithm implementation being used. What configuration elements are exposed depends on the needs of the EvictionAlgorithm implementation.

CacheLoaderConfig : only relevant if a Chapter 9, Cache Loaders 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 Section 8.1.2.2, “Buddy Replication” is used.) Also allows direct injection into the cache of needed external services like a JTA TransactionManager or a JGroups ChannelFactory .
