OSID - osid.recipe.DirectionAdminSession Service Interface Definition

Interface	osid.recipe.DirectionAdminSession
Implements	`osid.OsidSession`
Description	This session creates, updates, and deletes `Directions.` The data for create and update is provided by the consumer via the form object. `OsidForms` are requested for each create or update and may not be reused. Create and update operations differ in their usage. To create a `Direction,` a `DirectionForm` is requested using `getDirectionFormForCreate()` specifying the desired recipe and record `Types` or none if no record `Types` are needed. The returned `DirectionForm` will indicate that it is to be used with a create operation and can be used to examine metdata or validate data prior to creation. Once the `DirectionForm` is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each `DirectionForm` corresponds to an attempted transaction. For updates, `DirectionForms` are requested to the `Direction` `Id` that is to be updated using `getDirectionFormForUpdate().` Similarly, the `DirectionForm` has metadata about the data that can be updated and it can perform validation before submitting the update. The `DirectionForm` can only be used once for a successful update and cannot be reused. The delete operations delete `Directions.` To unmap a `Direction` from the current `Cookbook,` the `DirectionCookbookAssignmentSession` should be used. These delete operations attempt to remove the `Direction` itself thus removing it from all known `Cookbook` catalogs. This session includes an `Id` aliasing mechanism to assign an external `Id` to an internally assigned Id.
Method	getCookbookId
Description	Gets the `Cookbook` `Id` associated with this session.
Return	`osid.id.Id`		the `Cookbook Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getCookbook
Description	Gets the `Cookbook` associated with this session.
Return	`osid.recipe.Cookbook`		the cookbook
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	canCreateDirections
Description	Tests if this user can create `Directions.` A return of true does not guarantee successful authorization. A return of false indicates that it is known creating a `Direction` will result in a `PERMISSION_DENIED.` This is intended as a hint to an application that may opt not to offer create operations to an unauthorized user.

Compliance	`mandatory`		This method must be implemented.
Method	canCreateDirectionWithRecordTypes
