| RDFXMLParser | | public class RDFXMLParser extends RDFParserBase (Code) | | A parser for XML-serialized RDF. This parser operates directly on the SAX
events generated by a SAX-enabled XML parser. The XML parser should be
compliant with SAX2. You should specify which SAX parser should be used by
setting the org.xml.sax.driver property. This parser is not
thread-safe, therefore it's public methods are synchronized.
To parse a document using this parser:
- Create an instance of RDFXMLParser, optionally supplying it with your
own ValueFactory.
- Set the RDFHandler.
- Optionally, set the ParseErrorListener and/or ParseLocationListener.
- Optionally, specify whether the parser should verify the data it parses
and whether it should stop immediately when it finds an error in the data
(both default to true).
- Call the parse method.
Example code:
// Use the SAX2-compliant Xerces parser:
System.setProperty("org.xml.sax.driver", "org.apache.xerces.parsers.SAXParser");
RDFParser parser = new RDFXMLParser();
parser.setRDFHandler(myRDFHandler);
parser.setParseErrorListener(myParseErrorListener);
parser.setVerifyData(true);
parser.stopAtFirstError(false);
// Parse the data from inputStream, resolving any
// relative URIs against http://foo/bar:
parser.parse(inputStream, "http://foo/bar");

| RDFXMLParser | | public RDFXMLParser()(Code) | | Creates a new RDFXMLParser that will use a
ValueFactoryImpl to
create RDF model objects.
|
| RDFXMLParser | | public RDFXMLParser(ValueFactory valueFactory)(Code) | | Creates a new RDFXMLParser that will use the supplied
ValueFactory to create RDF model objects.
Parameters:
valueFactory - A ValueFactory. |
| parse | | public synchronized void parse(InputStream in, String baseURI) throws IOException, RDFParseException, RDFHandlerException(Code) | | Parses the data from the supplied InputStream, using the supplied baseURI
to resolve any relative URI references.
Parameters:
in - The InputStream from which to read the data, must not benull.
Parameters:
baseURI - The URI associated with the data in the InputStream, must not benull.
throws:
IOException - If an I/O error occurred while data was read from the InputStream.
throws:
RDFParseException - If the parser has found an unrecoverable parse error.
throws:
RDFHandlerException - If the configured statement handler encountered an unrecoverableerror.
throws:
IllegalArgumentException - If the supplied input stream or base URI is null. |
| parse | | public synchronized void parse(Reader reader, String baseURI) throws IOException, RDFParseException, RDFHandlerException(Code) | | Parses the data from the supplied Reader, using the supplied baseURI to
resolve any relative URI references.
Parameters:
reader - The Reader from which to read the data, must not be null.
Parameters:
baseURI - The URI associated with the data in the InputStream, must not benull.
throws:
IOException - If an I/O error occurred while data was read from the InputStream.
throws:
RDFParseException - If the parser has found an unrecoverable parse error.
throws:
RDFHandlerException - If the configured statement handler has encountered anunrecoverable error.
throws:
IllegalArgumentException - If the supplied reader or base URI is null. |
| setBaseURI | | protected void setBaseURI(ParsedURI baseURI)(Code) | | |
| setParseStandAloneDocuments | | public void setParseStandAloneDocuments(boolean standAloneDocs)(Code) | | Sets the parser in a mode to parse stand-alone RDF documents. In
stand-alone RDF documents, the enclosing rdf:RDF root element
is optional if this root element contains just one element (e.g.
rdf:Description.
