OSID - osid.ordering.rules.PriceEnablerStoreAssignmentSession Service Interface Definition

Interface	osid.ordering.rules.PriceEnablerStoreAssignmentSession
Implements	`osid.OsidSession`
Description	This session provides methods to re-assign `PriceEnabler` to `Store` mappings. A `PriceEnabler` may appear in multiple `Store` objects and removing the last reference to a `PriceEnabler` is the equivalent of deleting it. Each `Store` may have its own authorizations governing who is allowed to operate on it. Adding a reference of a `PriceEnabler` to another `Store` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignPriceEnablers
Description	Tests if this user can alter price enabler/store 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 lookup operations to unauthorized users.
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	canAssignPriceEnablersToStore
Description	Tests if this user can alter price enabler/store 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 lookup operations to unauthorized users.
Parameters	`osid.id.Id`	`storeId`	the `Id` of the `Store`
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Errors	NULL_ARGUMENT		`storeId` is `null`
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableStoreIds
Description	Gets a list of stores including and under the given store node in which any price enabler can be assigned.
Parameters	`osid.id.Id`	`storeId`	the `Id` of the `Store`
Return	`osid.id.IdList`		list of assignable store `Ids`
Errors	NULL_ARGUMENT		`storeId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableStoreIdsForPriceEnabler
Description	Gets a list of stores including and under the given store node in which a specific price enabler can be assigned.
Parameters	`osid.id.Id`	`storeId`	the `Id` of the `Store`
Parameters	`osid.id.Id`	`priceEnablerId`	the `Id` of the `PriceEnabler`
Return	`osid.id.IdList`		list of assignable store `Ids`
Errors	NULL_ARGUMENT		`storeId` or `priceEnablerId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignPriceEnablerToStore
Description	Adds an existing `PriceEnabler` to an `Store.`
Parameters	`osid.id.Id`	`priceEnablerId`	the `Id` of the `PriceEnabler`
Parameters	`osid.id.Id`	`storeId`	the `Id` of the `Store`
Errors	ALREADY_EXISTS		`priceEnablerId` is already assigned to `storeId`
	NOT_FOUND		`priceEnablerId` or `storeId` not found
	NULL_ARGUMENT		`priceEnablerId` or `storeId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignPriceEnablerFromStore
Description	Removes a `PriceEnabler` from an `Store.`
Parameters	`osid.id.Id`	`priceEnablerId`	the `Id` of the `PriceEnabler`
Parameters	`osid.id.Id`	`storeId`	the `Id` of the `Store`
Errors	NOT_FOUND		`priceEnablerId` or `storeId` not found or `priceEnablerId` is not assigned to `storeId`
	NULL_ARGUMENT		`priceEnablerId` or `storeId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	reassignPriceEnablerToStore
Description	Moves a `PriceEnabler` from one `Store` to another. Mappings to other `Stores` are unaffected.
Parameters	`osid.id.Id`	`priceEnablerId`	the `Id` of the `PriceEnabler`
	`osid.id.Id`	`fromStoreId`	the `Id` of the current `Store`
	`osid.id.Id`	`toStoreId`	the `Id` of the destination `Store`
Errors	NOT_FOUND		`priceEnabelrId, fromStoreId,` or `toStoreId` not found or `priceEnablerId` not mapped to `fromStoreId`
	NULL_ARGUMENT		`priceEnabelrId, fromStoreId,` or `toStoreId` is `null`
