Field Detail

INVALIDATE

public static final CacheBehaviour INVALIDATE

Cache maintenance is done by invalidating affected items of an operation and forcing the jcr2spi implementation to reload the item states when they are accessed next time. No event listener is used for cache maintenance even though the repository implementation might support observation.

OBSERVATION

public static final CacheBehaviour OBSERVATION

Cache maintenance is done using events from the repository. After an operation has been executed on the RepositoryService events are retrieved from the repository and the cache is updated based on the returned events. This strategy requires that the repository implementation supports observation.
