OSID - osid.lexicon.ParameterPressSession Service Interface Definition

Interface	osid.lexicon.ParameterPressSession
Implements	`osid.OsidSession`
Used By	`osid.lexicon.LexiconManager`
Used By	`osid.lexicon.LexiconProxyManager`
Description	This session provides methods to retrieve `Parameter` to `Press` mappings. A `Parameter` may appear in multiple `Press` objects. Each press may have its own authorizations governing who is allowed to look at it. This lookup session defines several views: comparative view: elements may be silently omitted or re-ordered plenary view: provides a complete result set or is an error condition
Method	canLookupParameterPressMappings
Description	Tests if this user can perform lookups of parameter/press mappings. A return of true does not guarantee successful authorization. A return of false indicates that it is known lookup methods in this session will result in a `PERMISSION_DENIED`. This is intended as a hint to an press that may opt not to offer lookup operations to unauthorized users.
Return	`boolean`		`false` if looking up mappings is not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	useComparativeParameterPressView
Description	The returns from the lookup methods may omit or translate elements based on this session, such as authorization, and not result in an error. This view is used when greater interoperability is desired at the expense of precision.
Compliance	`mandatory`		This method is must be implemented.
Method	usePlenaryParameterPressView
Description	A complete view of the `Parameter` and `Press` returns is desired. Methods will return what is requested or result in an error. This view is used when greater precision is desired at the expense of interoperability.
Compliance	`mandatory`		This method is must be implemented.
Method	getParameterIdsByPress
Description	Gets the list of `Parameter Ids` associated with a `Press`.
Parameters	`osid.id.Id`	`pressId`	`Id` of the `Press`
Return	`osid.id.IdList`		list of related parameter `Ids`
Errors	NOT_FOUND		`pressId` is not found
	NULL_ARGUMENT		`pressId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getParametersByPress
Description	Gets the list of parameters associated with a `Press`.
Parameters	`osid.id.Id`	`pressId`	`Id` of the `Press`
Return	`osid.lexicon.ParameterList`		list of related parameters
Errors	NOT_FOUND		`pressId` is not found
	NULL_ARGUMENT		`pressId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getParameterIdsByPresses
Description	Gets the list of `Parameter Ids` corresponding to a list of `Presses`.
Parameters	`osid.id.IdList`	`pressIds`	list of press `Ids`
Return	`osid.id.IdList`		list of parameter `Ids`
Errors	NULL_ARGUMENT		`pressIds` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getParametersByPresses
Description	Gets the list of parameters corresponding to a list of `Presses`.
Parameters	`osid.id.IdList`	`pressIds`	list of press `Ids`
Return	`osid.lexicon.ParameterList`		list of parameters
Errors	NULL_ARGUMENT		`pressIds` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getPressIdsByParameter
Description	Gets the `Press` `Ids` mapped to a `Parameter`.
Parameters	`osid.id.Id`	`parameterId`	`Id` of a `Parameter`
Return	`osid.id.IdList`		list of presses
Errors	NOT_FOUND		`parameterId` is not found
	NULL_ARGUMENT		`parameterId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getPressesByParameter
Description	Gets the `Presses` mapped to a `Parameter`.
Parameters	`osid.id.Id`	`parameterId`	`Id` of a `Parameter`
Return	`osid.lexicon.PressList`		list of presses
Errors	NOT_FOUND		`parameterId` is not found
	NULL_ARGUMENT		`parameterId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
