Interface PathQuerySession

All Superinterfaces:
AutoCloseable, Closeable, OsidSession, OsidSession
All Known Subinterfaces:
PathSearchSession
public interface PathQuerySession extends OsidSession

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

This session defines views that offer differing behaviors for searching.

  • federated graph view: searches include paths in graphs of which this graph is an ancestor in the graph hierarchy
  • isolated graph view: searches are restricted to paths in this graph

Paths may have a query record indicated by their respective record types. The query record is accessed via the PathQuery .

  • Method Details

    • getGraphId

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

    • getGraph

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

    • canSearchPaths

      boolean canSearchPaths()
      Tests if this user can perform Path 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.

    • useFederatedGraphView

      void useFederatedGraphView()
      Federates the view for methods in this session. A federated view will include paths in graphs which are children of this graph in the graph hierarchy.
      Compliance:
      mandatory - This method is must be implemented.

    • useIsolatedGraphView

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

    • getPathQuery

      PathQuery getPathQuery()
      Gets a path query.
      Returns:
      the path query
      Compliance:
      mandatory - This method must be implemented.

    • getPathsByQuery

      PathList getPathsByQuery(PathQuery pathQuery) throws OperationFailedException, PermissionDeniedException
      Gets a list of Paths matching the given path query.
      Parameters:
      pathQuery - the path query
      Returns:
      the returned PathList
      Throws:
      NullArgumentException - pathQuery is null
      OperationFailedException - unable to complete request
      PermissionDeniedException - authorization failure
      UnsupportedException - pathQuery is not of this service
      Compliance:
      mandatory - This method must be implemented.
