OSID - osid.logging.LogLookupSession Service Interface Definition

Interface	osid.logging.LogLookupSession
Implements	`osid.OsidSession`
Description	This session provides methods for retrieving `Log` objects. The `Log` represents a collection of log entries. This session defines views that offer differing behaviors when retrieving multiple objects. comparative view: elements may be silently omitted or re-ordered plenary view: provides a complete set or is an error condition Generally, the comparative view should be used for most applications as it permits operation even if there is data that cannot be accessed. For example, a browsing application may only need to examine the `Logs` it can access, without breaking execution. However, an assessment may only be useful if all `Logs` referenced by it are available, and a test-taking applicationmay sacrifice some interoperability for the sake of precision.
Method	canLookupLogs
Description	Tests if this user can perform `Log` 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 to unauthorized users.
Return	`boolean`		`false` if lookup methods are not authorized, `true` otherwise
Compliance	`mandatory`		This method must be implemented.
Method	useComparativeLogView
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	usePlenaryLogView
Description	A complete view of the `Log` 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	getLog
Description	Gets the `Log` specified by its `Id.` In plenary mode, the exact `Id` is found or a `NOT_FOUND` results. Otherwise, the returned `Log` may have a different `Id` than requested, such as the case where a duplicate `Id` was assigned to a `Log` and retained for compatibility.
Parameters	`osid.id.Id`	`logId`	`Id` of the `Log`
Return	`osid.logging.Log`		the log
Errors	NOT_FOUND		`logId` not found
	NULL_ARGUMENT		`logId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method is must be implemented.
Method	getLogsByIds
Description	Gets a `LogList` corresponding to the given `IdList.` In plenary mode, the returned list contains all of the logs 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 `Logs` may be omitted from the list and may present the elements in any order including returning a unique set.
Parameters	`osid.id.IdList`	`logIds`	the list of `Ids` to retrieve
Return	`osid.logging.LogList`		the returned `Log list`
Errors	NOT_FOUND		an `Id was` not found
	NULL_ARGUMENT		`logIds` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getLogsByGenusType
Description	Gets a `LogList` corresponding to the given log genus `Type` which does not include logs of genus types derived from the specified `Type.` In plenary mode, the returned list contains all known logs or an error results. Otherwise, the returned list may contain only those logs that are accessible through this session.
Parameters	`osid.type.Type`	`logGenusType`	a log genus type
Return	`osid.logging.LogList`		the returned `Log list`
Errors	NULL_ARGUMENT		`logGenusType` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getLogsByParentGenusType
Description	Gets a `LogList` corresponding to the given log genus `Type` and include any additional logs with genus types derived from the specified `Type.` In plenary mode, the returned list contains all known logs or an error results. Otherwise, the returned list may contain only those logs that are accessible through this session.
Parameters	`osid.type.Type`	`logGenusType`	a log genus type
Return	`osid.logging.LogList`		the returned `Log list`
Errors	NULL_ARGUMENT		`logGenusType` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getLogsByRecordType
Description	Gets a `LogList` containing the given log record `Type.` In plenary mode, the returned list contains all known logs or an error results. Otherwise, the returned list may contain only those logs that are accessible through this session.
Parameters	`osid.type.Type`	`logRecordType`	a log record type
Return	`osid.logging.LogList`		the returned `Log list`
Errors	NULL_ARGUMENT		`logRecordType` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getLogsByProvider
Description	Gets a `LogList` for a given provider. In plenary mode, the returned list contains all known logs or an error results. Otherwise, the returned list may contain only those logs that are accessible through this session.
Parameters	`osid.id.Id`	`resourceId`	a resource `Id`
Return	`osid.logging.LogList`		the returned `Log list`
Errors	NULL_ARGUMENT		`resourceId` is `null`
	OPERATION_FAILED		unable to complete request
	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
Method	getLogs
Description	Gets all `Logs.` In plenary mode, the returned list contains all known logs or an error results. Otherwise, the returned list may contain only those logs that are accessible through this session.
Return	`osid.logging.LogList`		a list of `Logs`
Errors	OPERATION_FAILED		unable to complete request
Errors	PERMISSION_DENIED		authorization failure
Compliance	`mandatory`		This method must be implemented.
