Interface CategoryBusinessAssignmentSession

All Superinterfaces:
AutoCloseable, Closeable, OsidSession, OsidSession
public interface CategoryBusinessAssignmentSession extends OsidSession

This session provides methods to re-assign Categories to Businesses . A Category may appear in multiple Businesses and removing the last reference to a Category is the equivalent of deleting it. Each Business may have its own authorizations governing who is allowed to operate on it.

Adding a reference of a Category to another Business is not a copy operation (eg: does not change its Id ).
