OSID - osid.course.chronicle.CourseEntryCourseCatalogAssignmentSession Service Interface Definition

Interface	osid.course.chronicle.CourseEntryCourseCatalogAssignmentSession
Implements	`osid.OsidSession`
Used By	`osid.course.chronicle.CourseChronicleManager`
Used By	`osid.course.chronicle.CourseChronicleProxyManager`
Description	This session provides methods to re-assign `CourseEntries` to `CourseCatalogs` . A `CourseEntry` may appear in multiple `CourseCatalogs` and removing the last reference to a `CourseEntry` is the equivalent of deleting it. Each `CourseCatalog` may have its own authorizations governing who is allowed to operate on it. Adding a reference of a `CourseEntry` to another `CourseCatalog` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignCourseEntries
Description	Tests if this user can alter course entry/course catalog mappings. A return of true does not guarantee successful authorization. A return of false indicates that it is known mapping methods in this session will result in a `PERMISSION_DENIED` . This is intended as a hint to an application that may opt not to offer assignment operations to unauthorized users.
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	canAssignCourseEntryToCourseCatalog
