      public static RDFPatch fileToPatch(String filename)
      Read an RDFPatch from a file.

    • nullPatch

      public static RDFPatch nullPatch()
      A immutable "nullop" patch - no transaction, no id.

    • emptyPatch

      public static RDFPatch emptyPatch()
      An immutable "empty" patch - a single transaction of no changes. Each call generates a new empty patch with a different id.

    • summary

      public static PatchSummary summary(RDFPatch patch)
      Create a brief summary of a patch.

      This function plays the patch.

    • collect

      public static RDFPatch collect(RDFPatch patch)
      Make sure a patch has been read from its input. The returned RDFPatch is not connected to an external resource like an InputStream.

    • build

      public static RDFPatch build(Consumer<RDFChangesCollector> filler)
      Build a patch.

    • rdf2patch

      public static RDFPatch rdf2patch(String rdfDataFile)
      RDF data file to patch. The patch has no Id or Previous - see withHeader(org.apache.jena.rdfpatch.RDFPatch, org.apache.jena.graph.Node, org.apache.jena.graph.Node).

    • withPrev

      public static RDFPatch withPrev(RDFPatch body, org.apache.jena.graph.Node prev)
      Create a patch with a specified "prev".

    • withPrev

      public static RDFPatch withPrev(RDFPatch patch, RDFPatch prevPatch)
      Create a patch with body from "patch" and previous set to the id of "prevPatch".

    • withHeader

      public static RDFPatch withHeader(RDFPatch body, org.apache.jena.graph.Node id, org.apache.jena.graph.Node prev)
      Create a patch with the id and prev as as given in the arguments, ignoring any header in the body patch.

    • withHeader

      public static RDFPatch withHeader(PatchHeader header, RDFPatch body)
      Create a patch with the header and body as given in the arguments, ignoring any header in the body patch.

    • makeHeader

      public static PatchHeader makeHeader(org.apache.jena.graph.Node id, org.apache.jena.graph.Node prev)
      Match a patch header with the given id and prev. Prev may be null.

    • read

      public static RDFPatch read(InputStream input)
      Read an RDFPatch from a file in text format Throws PatchException on patch parse error.

    • read

      public static RDFPatch read(InputStream input, org.apache.jena.riot.system.ErrorHandler errorHandler)

    • read

      public static RDFPatch read(String filename)
      Read an RDFPatch from a file.

    • readBinary

      public static RDFPatch readBinary(InputStream input)
      Read an RDFPatch from an input stream in binary format.

    • readBinary

      public static RDFPatch readBinary(String filename)
      Read an RDFPatch from a file.

    • readHeader

      public static PatchHeader readHeader(InputStream input)
      Read an RDFPatch header.

    • applyChange

      public static void applyChange(org.apache.jena.sparql.core.DatasetGraph dsg, RDFPatch patch)
      Apply changes from a RDFPatch to a DatasetGraph

    • applyChange

      public static void applyChange(org.apache.jena.sparql.core.DatasetGraph dsg, InputStream input)
      Apply changes from a text format input stream to a DatasetGraph

    • applyChange

      public static void applyChange(org.apache.jena.graph.Graph graph, RDFPatch patch)
      Apply changes from a RDFPatch to a Graph

    • applyChange

      public static void applyChange(org.apache.jena.graph.Graph graph, InputStream input)
