Interface SecurityContext

All Known Implementing Classes:
SecurityContextAllowAll, SecurityContextAllowNamedGraphs, SecurityContextAllowNone, SecurityContextView
public interface SecurityContext
A SecurityContext 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().

    • visibleGraphs

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

    • visibleGraphNames

      default Collection<String> visibleGraphNames()
      Collection of visible graph URI 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.

    • visableDefaultGraph

      boolean visableDefaultGraph()

    • createQueryExecution

      default org.apache.jena.query.QueryExecution createQueryExecution(String queryString, org.apache.jena.sparql.core.DatasetGraph dsg)

    • createQueryExecution

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

    • predicateQuad

      Predicate<org.apache.jena.sparql.core.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.

    • filterTDB

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