OSID - osid.provisioning.rules.ProvisionableEnablerDistributorAssignmentSession Service Interface Definition

Interface	osid.provisioning.rules.ProvisionableEnablerDistributorAssignmentSession
Implements	`osid.OsidSession`
Used By	`osid.provisioning.rules.ProvisioningRulesManager`
Used By	`osid.provisioning.rules.ProvisioningRulesProxyManager`
Description	This session provides methods to re-assign `ProvisionableEnabler` to `Distributor` mappings. A `ProvisionableEnabler` may appear in multiple `Distributor` catalogs and removing the last reference to a `ProvisionableEnabler` is the equivalent of deleting it. Each `Distributor` may have its own authorizations governing who is allowed to operate on it. Adding a reference of a `ProvisionableEnabler` to another `Distributor is` not a copy operation (eg: does not change its `Id` ).
Method	canAssignProvisionableEnablers
Description	Tests if this user can alter provisionable enabler/distributor 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. T` his 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	canAssignProvisionableEnablerToDistributor
Description	Tests if this user can alter provisionable enabler/distributor 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. T` his is intended as a hint to an application that may opt not to offer assignment operations to unauthorized users.
Parameters	`osid.id.Id`	`distributorId`	the `Id` of the `Distributor`
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Errors	NULL_ARGUMENT		`distributorId` is `null`
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableDistributorIds
Description	Gets a list of distributors including and under the given distributor node in which any provisionable enabler can be assigned.
Parameters	`osid.id.Id`	`distributorId`	the `Id` of the `Distributor`
Return	`osid.id.IdList`		list of assignable distributor `Ids`
Errors	NULL_ARGUMENT		`distributorId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableDistributorIdsForProvisionableEnabler
Description	Gets a list of distributors including and under the given distributor node in which a specific provisionable enabler can be assigned.
Parameters	`osid.id.Id`	`distributorId`	the `Id` of the `Distributor`
Parameters	`osid.id.Id`	`provisionableEnablerId`	the `Id` of the `ProvisionableEnabler`
Return	`osid.id.IdList`		list of assignable distributor `Ids`
Errors	NULL_ARGUMENT		`distributorId` or `provisionableEnablerId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignProvisionableEnablerToDistributor
Description	Adds an existing `ProvisionableEnabler` to a `Distributor` .
Parameters	`osid.id.Id`	`provisionableEnablerId`	the `Id` of the `ProvisionableEnabler`
Parameters	`osid.id.Id`	`distributorId`	the `Id` of the `Distributor`
Errors	ALREADY_EXISTS		`provisionableEnablerId` is already assigned to `distributorId`
	NOT_FOUND		`provisionableEnablerId` or `distributorId` not found
	NULL_ARGUMENT		`provisionableEnablerId` or `distributorId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignProvisionableEnablerFromDistributor
Description	Removes a `ProvisionableEnabler` from a `Distributor` .
Parameters	`osid.id.Id`	`provisionableEnablerId`	the `Id` of the `ProvisionableEnabler`
Parameters	`osid.id.Id`	`distributorId`	the `Id` of the `Distributor`
Errors	NOT_FOUND		`provisionableEnablerId` or `distributorId` not found or `provisionableEnablerId` not assigned to `distributorId`

	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	reassignProvisionableEnablerToDistributor
Description	Moves a `ProvisionableEnabler` from one `Distributor` to another. Mappings to other `Distributors` are unaffected.
