RDFPatchOps

public RDFPatchOps()

Method Details

fileToPatch

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,
 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,
 Node id,
 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(Node id,
 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,
 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(DatasetGraph dsg,
 RDFPatch patch)

Apply changes from a RDFPatch to a DatasetGraph

applyChange

public static void applyChange(DatasetGraph dsg,
 InputStream input)

Apply changes from a text format input stream to a DatasetGraph

applyChange

public static void applyChange(Graph graph,
 RDFPatch patch)

Apply changes from a RDFPatch to a Graph

applyChange

public static void applyChange(Graph graph,
 InputStream input)

Apply changes from a text format input stream to a Graph

changes

public static DatasetGraph changes(DatasetGraph dsgBase,
 RDFChanges changes)

Create a DatasetGraph that sends changes to a RDFChanges stream

changesPrinter

public static RDFChanges changesPrinter()

An RDFChanges that prints debug information to System.out. Output is for debugging - it is not legal text patch syntax.

textWriter

public static RDFChangesWriterText textWriter(OutputStream output)

An RDFChanges that prints RDFPatch syntax to an OutputStream in text format. The application must call RDFChanges.start and RDFChanges.finish.

changes

public static Graph changes(Graph graphBase,
 RDFChanges changes)

Create a Graph that sends changes to a RDFChanges stream

textWriter

public static DatasetGraph textWriter(DatasetGraph dsgBase,
 OutputStream out)

Create a DatasetGraph that writes changes to an OutputStream in text format. The caller is responsible for closing the OutputStream.

textWriter

public static Graph textWriter(Graph graph,
 OutputStream out)

Create a Graph that writes changes to an OutputStream in text format. The caller is responsible for closing the OutputStream.

write

Write a RDFPatch in text format

writeBinary

public static void writeBinary(OutputStream out,
 RDFPatch patch)

Write a RDFPatch in binary format

write

public static StreamRDF write(OutputStream out)

Write an StreamRDF out in RDFPatch text format. StreamRDF.start() and StreamRDF.finish() must be called; these bracket the patch in transaction markers TX and TC.

writeBinary
