OSID - osid.inventory.InventoryWarehouseAssignmentSession Service Interface Definition

Interface	osid.inventory.InventoryWarehouseAssignmentSession
Implements	`osid.OsidSession`
Used By	`osid.inventory.InventoryManager`
Used By	`osid.inventory.InventoryProxyManager`
Description	This session provides methods to re-assign `Inventories` to `Warehouses`. An `Inventory` may appear in multiple `Warehouse` objects and removing the last reference to an `Inventory` is the equivalent of deleting it. Each `Warehouse` may have its own authorizations governing who is allowed to operate on it. Adding a reference of an `Inventory` to another `Warehouse` is not a copy operation (eg: does not change its `Id`).
Method	canAssignInventories
Description	Tests if this user can alter inventory/warehouse 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	canAssignInventoriesToWarehouse
Description	Tests if this user can alter inventory/warehouse 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`.

Parameters	`osid.id.Id`	`warehouseId`	the `Id` of the `Warehouse`
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Errors	NULL_ARGUMENT		`warehouseId` is `null`
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableWarehouseIds
Description	Gets a list of warehouses including and under the given warehouse node in which any inventory can be assigned.
Parameters	`osid.id.Id`	`warehouseId`	the `Id` of the `Warehouse`
Return	`osid.id.IdList`		list of assignable warehouse `Ids`
Errors	NULL_ARGUMENT		`warehouseId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableWarehouseIdsForInventory
Description	Gets a list of warehouses including and under the given warehouse node in which a specific inventory can be assigned.
Parameters	`osid.id.Id`	`warehouseId`	the `Id` of the `Warehouse`
Parameters	`osid.id.Id`	`inventoryId`	the `Id` of the `Inventory`
Return	`osid.id.IdList`		list of assignable warehouse `Ids`
Errors	NULL_ARGUMENT		`warehouseId` or `inventoryId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignInventoryToWarehouse
Description	Adds an existing `Inventory` to a `Warehouse`.
Parameters	`osid.id.Id`	`inventoryId`	the `Id` of the `Inventory`
Parameters	`osid.id.Id`	`warehouseId`	the `Id` of the `Warehouse`
Errors	ALREADY_EXISTS		`inventoryId` is already assigned to `warehouseId`
	NOT_FOUND		`inventoryId` or `warehouseId` not found
	NULL_ARGUMENT		`inventoryId` or `warehouseId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignInventoryFromWarehouse
Description	Removes an `Inventory` from a `Warehouse`.
Parameters	`osid.id.Id`	`inventoryId`	the `Id` of the `Inventory`
Parameters	`osid.id.Id`	`warehouseId`	the `Id` of the `Warehouse`
Errors	NOT_FOUND		`inventoryId` or `warehouseId` not found or `inventoryId` not assigned to `warehouseId`
	NULL_ARGUMENT		`inventoryId` or `warehouseId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	reassignInventoryToWarehouse
Description	Moves an `Inventory` from one `Warehouse` to another. Mappings to other `Warehouses` are unaffected.
Parameters	`osid.id.Id`	`inventoryId`	the `Id` of the `Inventory`
	`osid.id.Id`	`fromWarehouseId`	the `Id` of the current `Warehouse`
	`osid.id.Id`	`toWarehouseId`	the `Id` of the destination `Warehouse`
Errors	ALREADY_EXISTS		`inventoryId` already assigned to `toWarehouseId`
	NOT_FOUND		`inventoryId, fromWarehouseId`, or `toWarehouseId` not found or `inventoryId` not mapped to `fromWarehouseId`
	NULL_ARGUMENT		`inventoryId, fromWarehouseId`, or `toWarehouseId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
