Interface PathSmartGraphSession

All Superinterfaces:

AutoCloseable, Closeable, OsidSession, OsidSession

public interface PathSmartGraphSession
extends OsidSession

This session manages queries and sequencing to create "smart" dynamic catalogs. A PathQuery can be retrieved from this session and mapped to this Graph to create a virtual collection of Paths. The paths may be sequenced using the PathSearchOrder from this session.

This Graph has a default query that matches any path and a default search order that specifies no sequencing. The queries may be examined using a PathQueryInspector. The query may be modified by converting the inspector back to a PathQuery.

Like all OsidSessions, PathSmartGraphSessions are dedicated to single processing threads and a single authenticated user.

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.

canManageSmartGraphs

boolean canManageSmartGraphs()

Tests if this user can manage smart graphs. A return of true does not guarantee successful authorization. A return of false indicates that it is known 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 operations to unauthorized users.

Returns:

false if smart graph management is not authorized, true otherwise

Compliance:

mandatory - This method must be implemented.

getPathQuery

PathQuery getPathQuery()

Gets a path query.

Returns:

the path query

Compliance:

mandatory - This method must be implemented.

getPathSearchOrder

PathSearchOrder getPathSearchOrder()

Gets a path search order.

Returns:

the path search order

Compliance:

mandatory - This method must be implemented.

applyPathQuery

void applyPathQuery(PathQuery pathQuery)
             throws OperationFailedException,
PermissionDeniedException

Applies a path query to this graph.

Parameters:

pathQuery - the path query

Throws:

NullArgumentException - pathQuery is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure occurred

UnsupportedException - pathQuery not of this service

Compliance:

mandatory - This method must be implemented.

inspectPathQuery

PathQueryInspector inspectPathQuery()
                             throws OperationFailedException,
PermissionDeniedException

Gets a path query inspector for this graph.

Returns:

the path query inspector

Throws:

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure occurred

Compliance:

mandatory - This method must be implemented.

applyPathSequencing

void applyPathSequencing(PathSearchOrder pathSearchOrder)
                  throws OperationFailedException,
PermissionDeniedException

Applies a path search order to this graph.

Parameters:

pathSearchOrder - the path search order

Throws:

NullArgumentException - pathSearchOrder is null

OperationFailedException - unable to complete request

PermissionDeniedException - authorization failure occurred

UnsupportedException - pathSearchOrder not of this service

Compliance:

mandatory - This method must be implemented.

getPathQueryFromInspector

PathQuery getPathQueryFromInspector(PathQueryInspector pathQueryInspector)

Gets a path query from an inspector.

Parameters:

pathQueryInspector - a path query inspector

Returns:

the path query

Throws:

NullArgumentException - pathQueryInspector is null

UnsupportedException - pathQueryInspector is not of this service

Compliance:

mandatory - This method must be implemented.
