public class CourseLink

extends Content

The CourseLink class is a representation of an intra-course link within the Bb Course Management System. CourseLink objects represent the "starting point" for a link originating from the content area of a course. Used in conjunction with the Link object, one can cause this content item to reference another item within the same course/organization.

As a sub-class of Content, there aren't many specific attributes. Functionally a CourseLink object is simply a content object with the content handler set to resource/x-bb-courselink, and the RenderType attribute set to Content.RenderType.LINK.

The proper way to use this object is as follows, due to the referential integrity constraints in the system:

1. Create the CourseLink object and save it
2. Create a Link object, setting any appropriate attributes.
3. Set the CourseLink as the "referrer" on the Link
4. Set the object you wish to "point" to as the "referred to" object on the Link
5. Persist the Link object.
