OSID - osid.resource.demographic.DemographicEnablerBinAssignmentSession Service Interface Definition

Interface	osid.resource.demographic.DemographicEnablerBinAssignmentSession
Implements	`osid.OsidSession`
Used By	`osid.resource.demographic.ResourceDemographicManager`
Used By	`osid.resource.demographic.ResourceDemographicProxyManager`
Description	This session provides methods to re-assign `DemographicEnabler` to `Bin` mappings. A `DemographicEnabler` may appear in multiple `Bin` objects and removing the last reference to a `DemographicEnabler` is the equivalent of deleting it. Each `Bin` may have its own authorizations governing who is allowed to operate on it. Adding a reference of a `DemographicEnabler` to another `Bin` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignDemographicEnablers
Description	Tests if this user can alter demographic enabler/bin 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	canAssignDemographicEnablersToBin
Description	Tests if this user can alter demographic enabler/bin 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`	`binId`	the `Id` of the `Bin`
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Errors	NULL_ARGUMENT		`binId` is `null`
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableBinIds
Description	Gets a list of bins including and under the given bin node in which any demographic enabler can be assigned.
Parameters	`osid.id.Id`	`binId`	the `Id` of the `Bin`
Return	`osid.id.IdList`		list of assignable bin `Ids`
Errors	NULL_ARGUMENT		`binId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableBinIdsForDemographicEnabler
Description	Gets a list of bins including and under the given bin node in which a specific demographic enabler can be assigned.
Parameters	`osid.id.Id`	`binId`	the `Id` of the `Bin`
Parameters	`osid.id.Id`	`demographicEnablerId`	the `Id` of the `DemographicEnabler`
Return	`osid.id.IdList`		list of assignable bin `Ids`
Errors	NULL_ARGUMENT		`binId` or `demographicEnablerId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignDemographicEnablerToBin
Description	Adds an existing `DemographicEnabler` to an `Bin` .
Parameters	`osid.id.Id`	`demographicEnablerId`	the `Id` of the `DemographicEnabler`
Parameters	`osid.id.Id`	`binId`	the `Id` of the `Bin`
Errors	NOT_FOUND		`demographicEnablerId` or `binId` not found
	NULL_ARGUMENT		`demographicEnablerId` or `binId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignDemographicEnablerFromBin
Description	Removes a `DemographicEnabler` from an `Bin` .
Parameters	`osid.id.Id`	`demographicEnablerId`	the `Id` of the `DemographicEnabler`
Parameters	`osid.id.Id`	`binId`	the `Id` of the `Bin`
Errors	NOT_FOUND		`demographicEnablerId` or `binId` not found
	NULL_ARGUMENT		`demographicEnablerId` or `binId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	reassignDemographicEnablerToBin
Description	Moves a `DemographicEnabler` from one `Bin` to another. Mappings to other `Bins` are unaffected.
Parameters	`osid.id.Id`	`demographicEnablerId`	the `Id` of the `DemographicEnabler`
	`osid.id.Id`	`fromBinId`	the `Id` of the current `Bin`
	`osid.id.Id`	`toBinId`	the `Id` of the destination `Bin`
Errors	ALREADY_EXISTS		`demographicEnablerId` already assigned to `toBinId`
	NOT_FOUND		`demographicEnablerId, fromBinId` , or `toBinId` not found or `demographicEnablerId` not mapped to `fromBinId`
	NULL_ARGUMENT		`demographicEnablerId, fromBinId` , or `toBinId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
