public SecurityContextAllowNone()

Method Details

visibleGraphs

public Collection<org.apache.jena.graph.Node> visibleGraphs()

Description copied from interface: SecurityContext

Collection of visible graph names.

This method returns null for "all" to avoid needing to calculate the current set of named graph names. A collection of no elements means no named graphs are visible.

Specified by:

visibleGraphs in interface SecurityContext

visableDefaultGraph

public boolean visableDefaultGraph()

Specified by:

visableDefaultGraph in interface SecurityContext

createQueryExecution

public org.apache.jena.query.QueryExecution createQueryExecution(org.apache.jena.query.Query query,
 org.apache.jena.sparql.core.DatasetGraph dsg)

Specified by:

createQueryExecution in interface SecurityContext

predicateQuad

public Predicate<org.apache.jena.sparql.core.Quad> predicateQuad()

Description copied from interface: SecurityContext

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

Specified by:

predicateQuad in interface SecurityContext

filterTDB

public void filterTDB(org.apache.jena.sparql.core.DatasetGraph dsg,
 org.apache.jena.query.QueryExecution qExec)

Description copied from interface: SecurityContext

Apply a filter suitable for the TDB-backed DatasetGraph, to the Context of the QueryExecution. This does not modify the DatasetGraph. Throws IllegalArgumentException if DatasetGraph is not a TDB1 or TDB2 backed dataset. May throw UnsupportedOperationException.

Specified by:

filterTDB in interface SecurityContext
