OSID - osid.resourcing.rules.AvailabilityEnablerFoundryAssignmentSession Service Interface Definition

Interface	osid.resourcing.rules.AvailabilityEnablerFoundryAssignmentSession
Implements	`osid.OsidSession`
Used By	`osid.resourcing.rules.ResourcingRulesManager`
Used By	`osid.resourcing.rules.ResourcingRulesProxyManager`
Description	This session provides methods to re-assign `AvailabilityEnabler` to `Foundry` mappings. an `AvailabilityEnabler` may appear in multiple `Foundry` objects and removing the last reference to an `AvailabilityEnabler` is the equivalent of deleting it. Each `Foundry` may have its own authorizations governing who is allowed to operate on it. Adding a reference of an `AvailabilityEnabler` to another `Foundry` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignAvailabilityEnablers
Description	Tests if this user can alter availability enabler/foundry 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	canAssignAvailabilityEnablersToFoundry
Description	Tests if this user can alter availability enabler/foundry 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`	`foundryId`	the `Id` of the `Foundry`
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Errors	NULL_ARGUMENT		`foundryId` is `null`
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableFoundryIds
Description	Gets a list of foundries including and under the given foundry node in which any availability enabler can be assigned.
Parameters	`osid.id.Id`	`foundryId`	the `Id` of the `Foundry`
Return	`osid.id.IdList`		list of assignable foundry `Ids`
Errors	NULL_ARGUMENT		`foundryId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableFoundryIdsForAvailabilityEnabler
Description	Gets a list of foundries including and under the given foundry node in which a specific availability enabler can be assigned.
Parameters	`osid.id.Id`	`foundryId`	the `Id` of the `Foundry`
Parameters	`osid.id.Id`	`availabilityEnablerId`	the `Id` of the `AvailabilityEnabler`
Return	`osid.id.IdList`		list of assignable foundry `Ids`
Errors	NULL_ARGUMENT		`foundryId` or `availabilityEnablerId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignAvailabilityEnablerToFoundry
Description	Adds an existing `AvailabilityEnabler` to a `Foundry` .
Parameters	`osid.id.Id`	`availabilityEnablerId`	the `Id` of the `AvailabilityEnabler`
Parameters	`osid.id.Id`	`foundryId`	the `Id` of the `Foundry`
Errors	ALREADY_EXISTS		`availabilityEnablerId` is already assigned to `foundryId`
	NOT_FOUND		`availabilityEnablerId` or `foundryId` not found
	NULL_ARGUMENT		`availabilityEnablerId` or `foundryId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignAvailabilityEnablerFromFoundry
Description	Removes an `AvailabilityEnabler` from a `Foundry` .
Parameters	`osid.id.Id`	`availabilityEnablerId`	the `Id` of the `AvailabilityEnabler`
Parameters	`osid.id.Id`	`foundryId`	the `Id` of the `Foundry`
Errors	NOT_FOUND		`availabilityEnablerId` or `foundryId` not found or `availabilityEnablerId` not assigned to `foundryId`
	NULL_ARGUMENT		`availabilityEnablerId` or `foundryId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	reassignAvailabilityEnablerToFoundry
Description	Moves an `AvailabilityEnabler` from one `Foundry` to another. Mappings to other `Foundries` are unaffected.
