Class CourseMembershipDbPersister.Default

java.lang.Object
  blackboard.persist.course.CourseMembershipDbPersister.Default

Enclosing interface:

CourseMembershipDbPersister

public static final class CourseMembershipDbPersister.Default
extends java.lang.Object

A utility class that provides quick access to the CourseMembershipDbPersister 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.
