OSID - osid.configuration.ParameterConfigurationAssignmentSession Service Interface Definition

Interface	osid.configuration.ParameterConfigurationAssignmentSession
Implements	`osid.OsidSession`
Description	This session provides methods to re-assign `Parameters` to `Configurations.` A `Parameter` may appear in multiple `Configurations` and removing the last reference to a `Parameter` is the equivalent of deleting it which may or may not be permitted. Each `Configuration` may have its own authorizations as to who is allowed to operate on it. Moving or adding a reference of a `Parameter` to another `Configuration` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignParameterConfigurations
Description	Tests if this user can change parameter configuration mappings. A return of true does not guarantee successful authorization. A return of false indicates that it is known all methods in this session will result in a `PERMISSION_DENIED.` This is intended as a hint to an application that may not wish to offer assignment operations.
Return	`boolean`		`false` if parameter configuration assignment is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	canAssignParametersToConfiguration
Description	Tests if this user can alter parameter/configuration parameters. A return of true does not guarantee successful authorization. A return of false indicates that it is known parameter 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`	`configurationId`	the `Id` of the `Configuration`
Return	`boolean`		`false` if configuration is not authorized, `true` otherwise
Errors	NULL_ARGUMENT		`configurationId` is `null`
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableConfigurationIds
Description	Gets a list of configurations including and under the given configuration node in which any parameter can be assigned.
Parameters	`osid.id.Id`	`configurationId`	the `Id` of the `Configuration`
Return	`osid.id.IdList`		list of assignable configuration `Ids`
Errors	NULL_ARGUMENT		`configurationId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getAssignableConfigurationIdsForParameter
Description	Gets a list of configurations including and under the given configuration node in which a specific parameter can be assigned.
Parameters	`osid.id.Id`	`configurationId`	the `Id` of the `Configuration`
Parameters	`osid.id.Id`	`parameterId`	the `Id` of the `Parameter`
Return	`osid.id.IdList`		list of assignable configuration `Ids`
Errors	NULL_ARGUMENT		`configurationId` or `parameterId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignParameterToConfiguration
Description	Adds an existing `Parameter` to a `Configuration.`
Parameters	`osid.id.Id`	`parameterId`	the `Id` of the `Parameter`
Parameters	`osid.id.Id`	`configurationId`	the `Id` of the `Configuration`
Errors	ALREADY_EXISTS		`parameterId` and `configurationId` already mapped
	NOT_FOUND		`parameterId` or `configurationId` not found
	NULL_ARGUMENT		`parameterId` or `configurationId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignParameterFromConfiguration
Description	Removes a `Parameter` from a `Configuration.`
Parameters	`osid.id.Id`	`parameterId`	the Id of the `Parameter`
Parameters	`osid.id.Id`	`configurationId`	the Id of the `Configuration`
Errors	NOT_FOUND		`parameterId` or `configurationId` not found or is not mapped
	NULL_ARGUMENT		`parameterId` or `configurationId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	reassignParameterToConfiguration
Description	Moves a `Parameter` from one `Configuration` to another. Mappings to other `Configurations` are unaffected.
Parameters	`osid.id.Id`	`parameterId`	the `Id` of the `Parameter`
	`osid.id.Id`	`fromConfigurationId`	the `Id` of the current `Configuration`
	`osid.id.Id`	`toConfigurationId`	the `Id` of the destination `Configuration`
Errors	NOT_FOUND		`parameterId fromConfigurationId,` or `toConfigurationId` not found or `creditId` not mapped to `fromConfigurationId`
	NULL_ARGUMENT		`parameterId, fromConfigurationId,` or `toConfigurationId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
