OSID - osid.configuration.rules.ParameterProcessorConfigurationAssignmentSession Service Interface Definition

Interface	osid.configuration.rules.ParameterProcessorConfigurationAssignmentSession
Implements	`osid.OsidSession`
Description	This session provides methods to re-assign `ParameterProcessor` to `Configuration` mappings. A `ParameterProcessor` may appear in multiple `Configuration` objects and removing the last reference to a `ParameterProcessor` is the equivalent of deleting it. Each `Configuration` may have its own authorizations governing who is allowed to operate on it. Adding a reference of a `ParameterProcessor` to another `Configuration` is not a copy operation (eg: does not change its `Id` ).
Method	canAssignParameterProcessors
Description	Tests if this user can alter parameter processor/configuration 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	canAssignParameterProcessorsToConfiguration
Description	Tests if this user can alter parameter processor/configuration 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`	`configurationId`	the `Id` of the `Configuration`
Return	`boolean`		`false` if mapping 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 processor 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	getAssignableConfigurationIdsForParameterProcessor
Description	Gets a list of configurations including and under the given configuration node in which a specific parameter processor can be assigned.
Parameters	`osid.id.Id`	`configurationId`	the `Id` of the `Configuration`
Parameters	`osid.id.Id`	`parameterProcessorId`	the `Id` of the `ParameterProcessor`
Return	`osid.id.IdList`		list of assignable configuration `Ids`
Errors	NULL_ARGUMENT		`configurationId` or `parameterProcessorId` is `null`
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	assignParameterProcessorToConfiguration
Description	Adds an existing `ParameterProcessor` to an `Configuration.`
Parameters	`osid.id.Id`	`parameterProcessorId`	the `Id` of the `ParameterProcessor`
Parameters	`osid.id.Id`	`configurationId`	the `Id` of the `Configuration`
Errors	ALREADY_EXISTS		`parameterProcessorId` is already assigned to `configurationId`
	NOT_FOUND		`parameterProcessorId` or `configurationId` not found
	NULL_ARGUMENT		`parameterProcessorId` or `configurationId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	unassignParameterProcessorFromConfiguration
Description	Removes a `ParameterProcessor` from a `Configuration.`
Parameters	`osid.id.Id`	`parameterProcessorId`	the `Id` of the `ParameterProcessor`
Parameters	`osid.id.Id`	`configurationId`	the `Id` of the `Configuration`
Errors	NOT_FOUND		`parameterProcessorId` or `configurationId` not found or `parameterProcessorId` is not assigned to `configurationId`
	NULL_ARGUMENT		`parameterProcessorId` or `configurationId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	reassignParameterProcessorToConfiguration
Description	Moves a `ParameterProcessor` from one `Configuration` to another. Mappings to other `Configurations` are unaffected.
Parameters	`osid.id.Id`	`parameterProcessorId`	the `Id` of the `ParameterProcessor`
	`osid.id.Id`	`fromConfigurationId`	the `Id` of the current `Configuration`
	`osid.id.Id`	`toConfigurationId`	the `Id` of the destination `Configuration`
Errors	NOT_FOUND		`parameterProcessorId fromConfigurationId,` or `toConfigurationId` not found or `parameterProcessorId` not mapped to `fromConfigurationId`
	NULL_ARGUMENT		`parameterProcessorId, fromConfigurationId,` or `toConfigurationId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
