OSID - osid.authorization.QualifierVaultAssignmentSession Service Interface Definition

Interface	osid.authorization.QualifierVaultAssignmentSession
Implements	`osid.OsidSession`
Used By	`osid.authorization.AuthorizationManager`
Used By	`osid.authorization.AuthorizationProxyManager`
Description	This session provides methods to re-assign `Qualifiers` to `Vaults`. A `Qualifier` may map to multiple `Vaults` and removing the last reference to a `Qualifier` is the equivalent of deleting it. Each `Vault` may have its own authorizations governing who is allowed to operate on it. Adding a reference of a `Qualifier` to another `Vault` is not a copy operation (eg: does not change its `Id`).
Method	canAssignQualifiers
Description	Tests if this user can alter qualifier/vault 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	canAssignQualifiersToVault
Description	Tests if this user can alter qualifier/vault 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`	`vaultId`	the `Id` of the `Vault`
Return	`boolean`		`false` if mapping is not authorized, `true` otherwise
Errors	NULL_ARGUMENT		`vaultId` is `null`
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableVaultIds
Description	Gets a list of vault including and under the given vault node in which any qualifier can be assigned.
Parameters	`osid.id.Id`	`vaultId`	the `Id` of the `Vault`
Return	`osid.id.IdList`		list of assignable vault `Ids`
Errors	NULL_ARGUMENT		`vaultId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableVaultIdsForQualifier
Description	Gets a list of vault including and under the given vault node in which a specific qualifier can be assigned.
Parameters	`osid.id.Id`	`vaultId`	the `Id` of the `Vault`
Parameters	`osid.id.Id`	`qualifierId`	the `Id` of the `Qualifier`
Return	`osid.id.IdList`		list of assignable vault `Ids`
Errors	NULL_ARGUMENT		`vaultId` or `qualifierId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignQualifierToVault
Description	Adds an existing `Qualifier` to a `Vault`.
Parameters	`osid.id.Id`	`qualifierId`	the `Id` of the `Qualifier`
Parameters	`osid.id.Id`	`vaultId`	the `Id` of the `Vault`
Errors	ALREADY_EXISTS		`qualifierId` is already assigned to `vaultId`
	NOT_FOUND		`qualifierId` or `vaultId` not found
	NULL_ARGUMENT		`qualifierId` or `vaultId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignQualifierFromVault
Description	Removes a `Qualifier` from a `Vault`.
Parameters	`osid.id.Id`	`qualifierId`	the `Id` of the `Qualifier`
Parameters	`osid.id.Id`	`vaultId`	the `Id` of the `Vault`
Errors	NOT_FOUND		`qualifierId` or `vaultId` not found or `qualifierId` not assigned to `vaultId`
	NULL_ARGUMENT		`qualifierId` or `vaultId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	reassignQualifierToVault
Description	Moves a `Qualifier` from one `Vault` to another. Mappings to other `Vaults` are unaffected.
Parameters	`osid.id.Id`	`qualifierId`	the `Id` of the `Qualifier`
	`osid.id.Id`	`fromVaultId`	the `Id` of the current `Vault`
	`osid.id.Id`	`toVaultId`	the `Id` of the destination `Vault`
Errors	ALREADY_EXISTS		`qualifierId` already assigned to `toVaultId`
	NOT_FOUND		`qualifierId, fromVaultId`, or `toVaultId` not found or `qualifierId`, not mapped to `fromVaultId`
	NULL_ARGUMENT		`qualifierId, fromVaultId`, or `toVaultId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
