Interface LogLookupSession

All Superinterfaces:
AutoCloseable, Closeable, OsidSession, OsidSession
public interface LogLookupSession extends OsidSession

This session provides methods for retrieving Logs . 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 Details

    • canLookupLogs

      boolean canLookupLogs()
      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.
      Returns:
      false if lookup methods are not authorized, true otherwise
      Compliance:
      mandatory - This method must be implemented.

    • useComparativeLogView

      void useComparativeLogView()
      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.

    • usePlenaryLogView

      void usePlenaryLogView()
      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.

    • getLog

      Log getLog(Id logId) throws NotFoundException, OperationFailedException, PermissionDeniedException
      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:
      logId - Id of the Log
      Returns:
      the log
      Throws:
      NotFoundException - logId not found
      NullArgumentException - logId is null
      OperationFailedException - unable to complete request
      PermissionDeniedException - authorization failure
      Compliance:
      mandatory - This method is must be implemented.

    • getLogsByIds

      LogList getLogsByIds(IdList logIds) throws NotFoundException, OperationFailedException, PermissionDeniedException
      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:
      logIds - the list of Ids to retrieve
      Returns:
      the returned Log list
      Throws:
      NotFoundException - an Id was not found
      NullArgumentException - logIds is null
      OperationFailedException - unable to complete request

      Compliance:
      mandatory - This method must be implemented.

    • getLogsByGenusType

      LogList getLogsByGenusType(Type logGenusType) throws OperationFailedException, PermissionDeniedException

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:
      logGenusType - a log genus type
      Returns:
      the returned Log list

      OperationFailedException - unable to complete request
      PermissionDeniedException - authorization failure
      Compliance:
      mandatory - This method must be implemented.

    • getLogsByParentGenusType

      LogList getLogsByParentGenusType(Type logGenusType) throws OperationFailedException, PermissionDeniedException
      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:
      logGenusType - a log genus type
      Returns:
      the returned Log list
      Throws:
      NullArgumentException - logGenusType is null
