OSID - osid.course.plan.PlanCourseCatalogAssignmentSession Service Interface Definition

Interface	osid.course.plan.PlanCourseCatalogAssignmentSession
Implements	`osid.OsidSession`
Description	This session provides methods to re-assign `Plans` to `Course Catalogs.` A `Plan` may map to multiple `CourseCatalogs` and removing the last reference to a `Plan` 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 `Plan` to another `CourseCatalog` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignPlans
Description	Tests if this user can alter plan/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	canAssignPlansToCourseCatalog

Method	getAssignableCourseCatalogIdsForPlan

Parameters	`osid.id.Id`	`planId`	the `Id` of the `Plan`
Return	`osid.id.IdList`		list of assignable course catalog `Ids`

Compliance	`mandatory`		This method must be implemented.
Method	unassignPlanFromCourseCatalog
Description	Removes a `Plan` from an `CourseCatalog.`
Parameters	`osid.id.Id`	`planId`	the `Id` of the `Plan`
Parameters	`osid.id.Id`	`courseCatalogId`	the `Id` of the `CourseCatalog`
Errors	NOT_FOUND		`planId` or `courseCatalogId` not found or `planId` not assigned to `courseCatalogId`
	NULL_ARGUMENT		`planId` or `courseCatalogId` is `null`
