java.lang.Object blackboard.persist.course.CourseDbPersister.Default
public static final class CourseDbPersister.Default
A utility class that provides quick access to the CourseDbPersister
instance associated with the default instance of the database BbPersistenceManager
.
This class and its method(s) are conveniences and should be used wisely.
If one is retrieving many Loader
and/or Persister
instances
within some scope, it will likely be more efficient to retrieve the default
database persistence manager directly, and then retrieve loader/persister
instances from it instead of making several calls to this and/or other
loader/persister utility classes.
