OSID - osid.resource.ResourceBinAssignmentSession Service Interface Definition

Interface	osid.resource.ResourceBinAssignmentSession
Implements	`osid.OsidSession`
Description	This session provides methods to re-assign `Resources` to `Bins.` A `Resource` may map to multiple `Bin` objects and removing the last reference to a `Resource` is the equivalent of deleting it. Each `Bin` may have its own authorizations governing who is allowed to operate on it. Moving or adding a reference of a `Resource` to another `Bin` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignResources
Description	Tests if this user can alter resource/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 assignment operations to unauthorized users.
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	canAssignResourcesToBin
Description	Tests if this user can alter resource/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 assignment 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 resource 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	getAssignableBinIdsForResource
Description	Gets a list of bins including and under the given bin node in which a specific resource can be assigned.
Parameters	`osid.id.Id`	`binId`	the `Id` of the `Bin`
Parameters	`osid.id.Id`	`resourceId`	the `Id` of the `Resource`
Return	`osid.id.IdList`		list of assignable bin `Ids`
Errors	NULL_ARGUMENT		`binId` or `resourceId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignResourceToBin
Description	Adds an existing `Resource` to a `Bin.`
Parameters	`osid.id.Id`	`resourceId`	the `Id` of the `Resource`
Parameters	`osid.id.Id`	`binId`	the `Id` of the `Bin`
Errors	ALREADY_EXISTS		`resourceId` is already assigned to `binId`
	NOT_FOUND		`resourceId` or `binId` not found
	NULL_ARGUMENT		`resourceId` or `binId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignResourceFromBin
Description	Removes a `Resource` from a `Bin.`
Parameters	`osid.id.Id`	`resourceId`	the `Id` of the `Resource`
Parameters	`osid.id.Id`	`binId`	the `Id` of the `Bin`
Errors	NOT_FOUND		`resourceId` or `binId` not found or `resourceId` not assigned to `binId`
	NULL_ARGUMENT		`resourceId` or `binId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
