Method Detail

loadByContentId

java.util.List loadByContentId(Id contentId)
                               throws PersistenceException

Loads a list of ContentStatus objects for a specific Content object. This automatically loads "semi-heavy", including CourseMembership and User records in the ContentStatus object. However, only the following fields are populated on the dependent objects:

• User.userName
• User.familyName
• User.givenName
• CourseMembership.role

Note that the load also discriminates rowStatus for both the user and membership records. I.e., disabled users (rowStatus == 0) will not be returned. However, unavailable users will be returned.

Parameters:

contentId - Id of the content object to retrieve the list.

Returns:

@throws PersistenceException

Throws:

PersistenceException
