org.olat.group.context.BGContext
Description:
A business group context is a container for groups that are used together as a set. Eg. all groups of a course, or a class with some subgroups, or a Lehrgang / Studiengang. Group contexts can be attached many courses. The group context can contain only business groups of one specific business group type. Default group contexts can only be used for one resource (one association allowed). This is configured by the setDefaultContext() method.
