Interface DeviceEnablerQuerySession

All Superinterfaces:
AutoCloseable, Closeable, OsidSession, OsidSession
All Known Subinterfaces:
DeviceEnablerSearchSession
public interface DeviceEnablerQuerySession extends OsidSession

This session provides methods for searching among DeviceEnabler objects. The search query is constructed using the DeviceEnablerQuery .

This session defines views that offer differing behaviors for searching.

  • federated system view: searches include device enablers in systems of which this system is an ancestor in the system hierarchy
  • isolated system view: searches are restricted to device enablers in this system

Device constrainer enablers may have a query record indicated by their respective record types. The query record is accessed via the DeviceEnablerQuery .

  • Method Details

    • getSystemId

      Id getSystemId()
      Gets the System Id associated with this session.
      Returns:
      the System Id associated with this session
      Compliance:
      mandatory - This method must be implemented.

    • getSystem

      System getSystem() throws OperationFailedException, PermissionDeniedException
      Gets the System associated with this session.
      Returns:
      the system
      Throws:
      OperationFailedException - unable to complete request
      PermissionDeniedException - authorization failure
      Compliance:
      mandatory - This method must be implemented.

    • canSearchDeviceEnablers

      boolean canSearchDeviceEnablers()
      Tests if this user can perform DeviceEnabler 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 not offer lookup operations to unauthorized users.
      Returns:
      false if search methods are not authorized, true otherwise
      Compliance:
      mandatory - This method must be implemented.

    • useFederatedSystemView

      void useFederatedSystemView()
      Federates the view for methods in this session. A federated view will include device enablers in systems which are children of this broker in the system hierarchy.
      Compliance:
      mandatory - This method is must be implemented.

    • useIsolatedSystemView

      void useIsolatedSystemView()
      Isolates the view for methods in this session. An isolated view restricts lookups to this system only.
      Compliance:
      mandatory - This method is must be implemented.

    • getDeviceEnablerQuery

      DeviceEnablerQuery getDeviceEnablerQuery()
      Gets a device enabler query.
      Returns:
      the device enabler query
      Compliance:
      mandatory - This method must be implemented.

    • getDeviceEnablersByQuery

      DeviceEnablerList getDeviceEnablersByQuery(DeviceEnablerQuery deviceEnablerQuery) throws OperationFailedException, PermissionDeniedException
      Gets a list of DeviceEnablers matching the given search.
      Parameters:
      deviceEnablerQuery - the device constraienr enabler query
      Returns:
      the returned DeviceEnablerList
      Throws:
      NullArgumentException - deviceEnablerQuery is null
      OperationFailedException - unable to complete request
      PermissionDeniedException - authorization failure
      UnsupportedException - deviceEnablerQuery is not of this service
      Compliance:
      mandatory - This method must be implemented.
