OSID - osid.installation.DepotAdminSession Service Interface Definition

Interface	osid.installation.DepotAdminSession
Implements	`osid.OsidSession`
Implemented By	`osid.installation.batch.DepotBatchAdminSession`
Used By	`osid.installation.InstallationManager`
Used By	`osid.installation.InstallationProxyManager`
Description	This session creates, updates, and deletes `Depots`. 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 `Depot`, a `DepotForm` is requested using `getDepotFormForCreate()` specifying the desired record `Types` or none if no record `Types` are needed. The returned `DepotForm` 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 `DepotForm` is submiited to a create operation, it cannot be reused with another create operation unless the first operation was unsuccessful. Each `DepotForm` corresponds to an attempted transaction. For updates, `DepotForms` are requested to the `Depot` `Id` that is to be updated using `getDepotFormForUpdate()`. Similarly, the `DepotForm` has metadata about the data that can be updated and it can perform validation before submitting the update. The `Depot` can only be used once for a successful update and cannot be reused. The delete operations delete `Depots`.This session also includes an `Id` aliasing mechanism to assign an external `Id` to an internally assigned Id.
Method	canCreateDepots
Description	Tests if this user can create `Depots`. A return of true does not guarantee successful authorization. A return of false indicates that it is known creating a `Depot` will result in a `PERMISSION_DENIED`. This is intended as a hint to an application that may not wish to offer create operations to unauthorized users.
Return	`boolean`		`false` if `Depot` creation is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	canCreateDepotWithRecordTypes
Description	Tests if this user can create a single `Depot` using the desired record types. While `InstallationManager.getDepotRecordTypes()` can be used to examine which records are supported, this method tests which record(s) are required for creating a specific `Depot`. Providing an empty array tests if a `Depot` can be created with no records.
Parameters	`osid.type.Type[]`	`depotRecordTypes`	array of depot record types
Return	`boolean`		`true` if `Depot` creation using the specified `Types` is supported, `false` otherwise
Errors	NULL_ARGUMENT		`depotRecordTypes` is `null`
Compliance	`mandatory`		This method must be implemented.
Method	getDepotFormForCreate
Description	Gets the depot form for creating new depots. A new form should be requested for each create transaction.
Parameters	`osid.type.Type[]`	`depotRecordTypes`	array of depot record types
Return	`osid.installation.DepotForm`		the depot form
Errors	NULL_ARGUMENT		`depotRecordTypes` is `null`

Method	canUpdateDepots
Description	Tests if this user can update `Depots`. A return of true does not guarantee successful authorization. A return of false indicates that it is known updating a `Depot` will result in a `PERMISSION_DENIED`.

Return	`boolean`		`false` if `Depot` modification is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	canUpdateDepot
Description	Tests if this user can update a specified `Depot`. A return of true does not guarantee successful authorization.
