Class SecurityContextView

java.lang.Object

org.apache.jena.fuseki.access.SecurityContextView

All Implemented Interfaces:

SecurityContext

public class SecurityContextView
extends Object
implements SecurityContext

A SecurityContextView is the things actor (user, role) is allowed to do. Currently version: the set of graphs, by graph name, they can access. It can be inverted into a "deny" policy with Predicate.negate().

Method Detail

visibleGraphs

public Collection<Node> visibleGraphs()

Description copied from interface: SecurityContext

Collection of visible graph names. This method return null for null for "all" to avoid needing to calculate the current set of named graph names.

Specified by:

visibleGraphs in interface SecurityContext

visableDefaultGraph

public boolean visableDefaultGraph()

Specified by:

visableDefaultGraph in interface SecurityContext

createQueryExecution

public QueryExecution createQueryExecution(String queryString,
                                           DatasetGraph dsg)

Specified by:

createQueryExecution in interface SecurityContext

createQueryExecution

public QueryExecution createQueryExecution(Query query,
                                           DatasetGraph dsg)

Specified by:

createQueryExecution in interface SecurityContext

filterTDB

public void filterTDB(DatasetGraph dsg,
                      QueryExecution qExec)

Apply a filter suitable for the TDB-backed DatasetGraph, to the Context of the QueryExecution. This does not modify the DatasetGraph.

Specified by:

filterTDB in interface SecurityContext

predicateQuad

public Predicate<Quad> predicateQuad()

Quad filter to reflect the security policy of this SecurityContext. It is better to call createQueryExecution(Query, DatasetGraph) which may be more efficient.

Specified by:

predicateQuad in interface SecurityContext

toString

public String toString()

Overrides:

toString in class Object
