Method Detail

getUpdateableEntities

java.util.Set<EntityI> getUpdateableEntities()

A Set of EntityI Instances that will be registered in the DBMan listener and whose procs will be queried on changes.

Returns:

a set of Entities to keep updated.

isRelevantRegardingKeepClasses

boolean isRelevantRegardingKeepClasses(java.lang.Class<? extends BOI> clazz)

Returns:

true, if the passed Class is one of classes (or a subclass of one) that will be kept updated. Will only be called on classes defined by getUpdateableEntities

isLoadAnyChangesIntoCache

boolean isLoadAnyChangesIntoCache()

Returns:

true if any changed BOs that fit UpdateableEntities and isRelevantRegardingKeepClasses should be loaded into the cache, even if those weren't there before. Those BOs might implicitly update the GC Strategy (FIXME this behaviour could change). Insertion of those loaded BOs can be observed through the CacheListener Interface. false, if only BOs that are already inside the cache should be handled or if they were added to an already unlazied manyrelation of a BO in the cache.
