  • Method Details

    • start

      public void start()
      Description copied from interface: RDFChanges
      Start processing. The exact meaning is implementation dependent. This should be paired with a RDFChanges.finish().
      Specified by:
      start in interface RDFChanges

    • finish

      public void finish()
      Description copied from interface: RDFChanges
      Finish processing. The exact meaning is implementation dependent. This should be paired with a RDFChanges.start().
      Specified by:
      finish in interface RDFChanges

    • header

      public void header(String field, org.apache.jena.graph.Node value)
      Description copied from interface: RDFChanges
      Header field. Headers are metadata about the changes being made.
      Specified by:
      header in interface RDFChanges

    • add

      public void add(org.apache.jena.graph.Node g, org.apache.jena.graph.Node s, org.apache.jena.graph.Node p, org.apache.jena.graph.Node o)
      Description copied from interface: RDFChanges
      Notification that a quad or triple is added. A stream of Triples outside a dataset will have null for the graph name. Inside an RDF Dataset, it may be more natural to use "urn:x-arq:DefaultGraph" or "urn:x-arq:DefaultGraphNode" in which case test with Quad.isDefaultGraph(Node).

      It is not defined whether the add happens before or after this notification all.

      Specified by:
      add in interface RDFChanges

    • delete

      public void delete(org.apache.jena.graph.Node g, org.apache.jena.graph.Node s, org.apache.jena.graph.Node p, org.apache.jena.graph.Node o)
      Description copied from interface: RDFChanges
      Notification that a quad or triple is deleted. A stream of Triples outside a dataset will have null for the graph name. Inside an RDF Dataset, it may be more natural to use "urn:x-arq:DefaultGraph" or "urn:x-arq:DefaultGraphNode" in which case test with Quad.isDefaultGraph(Node).

      It is not defined whether the delete happens before or after this notification all.

      Specified by:
      delete in interface RDFChanges

    • addPrefix

      public void addPrefix(org.apache.jena.graph.Node gn, String prefix, String uriStr)
      Description copied from interface: RDFChanges
      Add a prefix. The graph name follows the same rules as RDFChanges.add(org.apache.jena.graph.Node, org.apache.jena.graph.Node, org.apache.jena.graph.Node, org.apache.jena.graph.Node).
      Specified by:
      addPrefix in interface RDFChanges

    • deletePrefix

      public void deletePrefix(org.apache.jena.graph.Node gn, String prefix)
      Description copied from interface: RDFChanges
      Delete a prefix. The graph name follows the same rules as RDFChanges.add(org.apache.jena.graph.Node, org.apache.jena.graph.Node, org.apache.jena.graph.Node, org.apache.jena.graph.Node).
      Specified by:
      deletePrefix in interface RDFChanges

    • txnBegin

      public void txnBegin()
      Description copied from interface: RDFChanges
      Indicator that a transaction begins, or becomes a write transaction.
      Specified by:
      txnBegin in interface RDFChanges

    • txnCommit

      public void txnCommit()
      Description copied from interface: RDFChanges
      Indicator that a transaction commits. If this throws an exception, the transaction will be aborted locally and not commit after all.
      Specified by:
      txnCommit in interface RDFChanges

    • txnAbort

      public void txnAbort()
      Description copied from interface: RDFChanges
      Indicator that a transaction aborts
      Specified by:
      txnAbort in interface RDFChanges

    • segment

      public void segment()
      Description copied from interface: RDFChanges
      Segment marker.

      A segment is a number of transactions; the grouping rationale is not defined by RDF Patch.

      It might be used to indicate a logical collection of change transactions in a long stream of transactions.

      There is no guarantee it will be used.

      Segments must contain complete transactions.
      Segments must not span start-finish pairs.

      Specified by:
      segment in interface RDFChanges
