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

Interface	osid.provisioning.rules.QueueProcessorEnablerDistributorAssignmentSession
Implements	`osid.OsidSession`
Description	This session provides methods to re-assign `QueueProcessorEnabler` to `Distributor` mappings. a `QueueProcessorEnabler` may appear in multiple `Distributor` objects and removing the last reference to a `QueueProcessorEnabler` 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 `QueueProcessorEnabler` to another `Distributor` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignQueueProcessorEnablers
Description	Tests if this user can alter queue processor 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.` 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	canAssignQueueProcessorEnablersToDistributor
Description	Tests if this user can alter queue processor 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.` This is intended as a hint to an application that may opt not to offer lookup 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 queue processor 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	getAssignableDistributorIdsForQueueProcessorEnabler
Description	Gets a list of distributors including and under the given distributor node in which a specific queue processor enabler can be assigned.
Parameters	`osid.id.Id`	`distributorId`	the `Id` of the `Distributor`
Parameters	`osid.id.Id`	`queueProcessorEnablerId`	the `Id` of the `QueueProcessorEnabler`
Return	`osid.id.IdList`		list of assignable distributor `Ids`
Errors	NULL_ARGUMENT		`distributorId` or `queueProcessorEnablerId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignQueueProcessorEnablerToDistributor
Description	Adds an existing `QueueProcessorEnabler` to a `Distributor.`
Parameters	`osid.id.Id`	`queueProcessorEnablerId`	the `Id` of the `QueueProcessorEnabler`
Parameters	`osid.id.Id`	`distributorId`	the `Id` of the `Distributor`
Errors	ALREADY_EXISTS		`queueProcessorEnablerId` is already assigned to `distributorId`
	NOT_FOUND		`queueProcessorEnablerId` or `distributorId` not found
	NULL_ARGUMENT		`queueProcessorEnablerId` or `distributorId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignQueueProcessorEnablerFromDistributor
Description	Removes a `QueueProcessorEnabler` from a `Distributor.`
Parameters	`osid.id.Id`	`queueProcessorEnablerId`	the `Id` of the `QueueProcessorEnabler`
Parameters	`osid.id.Id`	`distributorId`	the `Id` of the `Distributor`
Errors	NOT_FOUND		`queueProcessorEnablerId` or `distributorId` not found or `queueProcessorEnablerId` not assigned to `distributorId`
	NULL_ARGUMENT		`queueProcessorEnablerId` or `distributorId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
