OSID - osid.profile.ProfileItemLookupSession Service Interface Definition

Interface	osid.profile.ProfileItemLookupSession
Implements	`osid.OsidSession`
Used By	`osid.profile.ProfileManager`
Used By	`osid.profile.ProfileProxyManager`
Description	This session provides methods for retrieving `ProfileItems`. This session defines two sets of views which offer differing behaviors when retrieving multiple objects. comparative view: elements may be silently omitted or re-ordered plenary view: provides a complete and ordered result set or is an error condition isolated profile view: All profile item methods in this session operate, retrieve and pertain to profile items defined explicitly in the current profile. Using an isolated view is useful for managing profile items with the `ProfileItemAdminSession`. federated profile view: All profile item methods in this session operate, retrieve and pertain to all profile items defined in this profile and any other profiles implicitly available in this profile through profile inheritence. Generally, the comparative view should be used for most applications as it permits operation even if there a particular element is inaccessible. For example, a hierarchy output can be plugged into a lookup method to retrieve all objects known to a hierarchy, but it may not be necessary to break execution if a node from the hierarchy no longer exists. However, some administrative applications may need to know whether it had retrieved an entire set of objects and may sacrifice some interoperability for the sake of precision. ProfileItems may have an additional records indicated by their respective record types.
Method	getProfileId
Description	Gets the `Profile` `Id` associated with this session.
Return	`osid.id.Id`		the `Profile Id` associated with this session
Compliance	`mandatory`		This method must be implemented.
Method	getProfile
Description	Gets the `Profile` associated with this session.
Return	`osid.profile.Profile`		the `Profile` associated with this session
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	canLookupProfileItems
Description	Tests if this user can perform `ProfileItem` lookups. 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 opt not to offer lookup operations.
Return	`boolean`		`false` if lookup methods are not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	useComparativeProfileItemView
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	usePlenaryProfileItemView
Description	A complete view of the `ProfileItem` 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	useFederatedProfileView
Description	Federates the view for methods in this session. A federated view will include items in profiles which are children of this profile in the profile hierarchy.
Compliance	`mandatory`		This method is must be implemented.
Method	useIsolatedProfileView
Description	Isolates the view for methods in this session. An isolated view restricts lookups to this profile only.
Compliance	`mandatory`		This method is must be implemented.
Method	getProfileItem
Description	Gets the `ProfileItem` specified by its `Id`. In plenary mode, the exact `Id` is found or a `NOT_FOUND` results. Otherwise, the returned `ProfileItem` may have a different `Id` than requested, such as the case where a duplicate `Id` was assigned to a `ProfileItem` and retained for compatibility.
Parameters	`osid.id.Id`	`profileItemId`	the `Id` of the `ProfileItem` to retrieve
Return	`osid.profile.ProfileItem`		the returned `ProfileItem`
Errors	NOT_FOUND		no `ProfileItem` found with the given `Id`
	NULL_ARGUMENT		`profileItemId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getProfileItemsByIds
Description	Gets a `ProfileItemList` corresponding to the given `IdList`.In plenary mode, the returned list contains all of the profile items specified in the `Id` list, in the order of the list, including duplicates, or an error results if an `Id` in the supplied list is not found or inaccessible. Otherwise, inaccessible `ProfileItems` may be omitted from the list and may present the elements in any order including returning a unique set.
Parameters	`osid.id.IdList`	`profileItemIds`	the list of `Ids` to retrieve
Return	`osid.profile.ProfileItemList`		the returned `ProfileItem` list
Errors	NOT_FOUND		an `Id was` not found
	NULL_ARGUMENT		`profileItemIds` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getProfileItemsByGenusType
Description	Gets a `ProfileItemList` corresponding to the given profile item genus `Type` which does not include profile items of genus types derived from the specified `Type`. In plenary mode, the returned list contains all known profile items or an error results. Otherwise, the returned list may contain only those profile items that are accessible through this session.
Parameters	`osid.type.Type`	`profileItemGenusType`	a profile item genus type
Return	`osid.profile.ProfileItemList`		the returned `ProfileItem` list
Errors	NULL_ARGUMENT		`profileItemGenusType` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getProfileItemsByParentGenusType
Description	Gets a `ProfileItemList` corresponding to the given profile item genus `Type` and include any additional profile item with genus types derived from the specified `Type`. In plenary mode, the returned list contains all known profile items or an error results. Otherwise, the returned list may contain only those profile items that are accessible through this session.
Parameters	`osid.type.Type`	`profileItemGenusType`	a profile item genus type
Return	`osid.profile.ProfileItemList`		the returned `ProfileItem` list
Errors	NULL_ARGUMENT		`profileItemGenusType` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getProfileItemsByRecordType
Description	Gets a `ProfileItemList` containing the given profile item record `Type`.In plenary mode, the returned list contains all known profile items or an error results. Otherwise, the returned list may contain only those profile items that are accessible through this session.
Parameters	`osid.type.Type`	`profileItemRecordType`	a profile item record type
Return	`osid.profile.ProfileItemList`		the returned `ProfileItem` list
Errors	NULL_ARGUMENT		`profileItemRecordType` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getProfileItems
Description	Gets all `ProfileItems`. In plenary mode, the returned list contains all known profile items or an error results. Otherwise, the returned list may contain only those profile items that are accessible through this session.
