Implements	`osid.OsidSession`
Used By	`osid.offering.rules.OfferingRulesManager`
Used By	`osid.offering.rules.OfferingRulesProxyManager`
Description	This session provides methods to apply `OfferingConstrainers` to `CanonicalUnits` to constrain the offerings for a canonical unit. A `CanonicalUnit` with multiple `OfferingConstrainers` means any positive rule evaluation across the result in an effective `CanonicalUnit`.
Method	getCatalogueId
Description	Gets the `Catalogue` `Id` associated with this session.
Return	`osid.id.Id`		the `Catalogue Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getCatalogue
Description	Gets the `Catalogue` associated with this session.
Return	`osid.offering.Catalogue`		the catalogue
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	canAssignOfferingConstrainers
Description	Tests if this user can alter offering constrainer/canonical unit 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	assignOfferingConstrainerToCanonicalUnit
Description	Adds an existing `OfferingConstrainer` to a `CanonicalUnit`.

	NOT_FOUND		`offeringConstrainerId` or `canonicalUnitId` not found
	NULL_ARGUMENT		`offeringConstrainerId` or `canonicalUnitId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.

Return	`boolean`		`false` if `OfferingConstrainer` ordering is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	moveOfferingConstrainerAhead
Description	Reorders offering constrainers for a canonical unit by moving the specified offering constrainer in front of a reference offering constrainer.

	`osid.id.Id`	`canonicalUnitId`	the `Id` of a `CanonicalUnit`
	`osid.id.Id`	`referenceId`	the reference offering constrainer `Id`
Errors	NOT_FOUND		`offeringConstrainerId, canonicalUnitId`, or `referenceId` not found or, `offeringConstrainerId` or `referenceId` not related to `canonicalUnitId`
	NULL_ARGUMENT		`offeringConstrainerId, canonicalUnitId`, or `referenceId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
