OSID - osid.installation.InstallationPackageDepotAssignmentSession Service Interface Definition

Interface	osid.installation.InstallationPackageDepotAssignmentSession
Implements	`osid.OsidSession`
Description	This session provides methods to re-assign `InstallationPackages` to `Depots`. A `InstallationPackage` may map to multiple `Depots` and removing the last reference to an `InstallationPackage` is the equivalent of deleting it. Each `Depot` may have its own authorizations governing who is allowed to operate on it. Moving or adding a reference of a `InstallationPackage` to another `Depot` is not a copy operation (eg: does not change its `Id`).
Method	canAssignInstallationPackages
Description	Tests if this user can alter package/depot 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	canAssignInstallationPackagesToDepot
Description	Tests if this user can alter package/depot 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.
Parameters	`osid.id.Id`	`depotId`	the `Id` of the `Depot`
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Errors	NULL_ARGUMENT		`depotId` is `null`
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableDepotIds
Description	Gets a list of depot including and under the given depot node in which any package can be assigned.
Parameters	`osid.id.Id`	`depotId`	the `Id` of the `Depot`
Return	`osid.id.IdList`		list of assignable depot `Ids`
Errors	NULL_ARGUMENT		`depotId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableDepotIdsForInstallationPackage
Description	Gets a list of depot including and under the given depot node in which a specific package can be assigned.
Parameters	`osid.id.Id`	`depotId`	the `Id` of the `Depot`
Parameters	`osid.id.Id`	`installationPackageId`	the `Id` of the `InstallationPackage`
Return	`osid.id.IdList`		list of assignable depot `Ids`
Errors	NULL_ARGUMENT		`depotId` or `installationPackageId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignInstallationPackageToDepot
Description	Adds an existing `InstallationPackage` to a `Depot`.
Parameters	`osid.id.Id`	`installationPackageId`	the `Id` of the `InstallationPackage`
Parameters	`osid.id.Id`	`depotId`	the `Id` of the `Depot`
Errors	ALREADY_EXISTS		`installationPackageId` is already assigned to `depotId`
	NOT_FOUND		`installationPackageId` or `depotId` not found
	NULL_ARGUMENT		`installationPackageId` or `depotId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignInstallationPackageFromDepot
Description	Removes a `InstallationPackage` from a `Depot`.
Parameters	`osid.id.Id`	`installationPackageId`	the `Id` of the `InstallationPackage`
Parameters	`osid.id.Id`	`depotId`	the `Id` of the `Depot`
Errors	NOT_FOUND		`installationPackageId` or `depotId` not found or `installationPackageId` not assigned to `depotId`
	NULL_ARGUMENT		`installationPackageId` or `depotId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	reassignInstallationPackageToDepot
Description	Moves a `InstallationPackage` from one `Depot` to another. Mappings to other `Depots` are unaffected.
Parameters	`osid.id.Id`	`installationPackageId`	the `Id` of the `InstallationPackage`
