public JenaReader()

Method Detail

read

public void read(Model m,
                 java.lang.String url)
          throws JenaException

Reads from url, using url as base, adding triples to model. Uses content negotiation to ask for application/rdf+xml, if available.

Specified by:

read in interface RDFReaderI

Parameters:

m - A model to add triples to.

url - The URL of the RDF/XML document.

Throws:

JenaException

read

public void read(Model m,
                 java.io.Reader reader,
                 java.lang.String xmlBase)
          throws JenaException

Reads from reader, using base URI xmlbase, adding triples to model. If xmlbase is "" then relative URIs may be added to model.

Specified by:

read in interface RDFReaderI

Parameters:

m - A model to add triples to.

reader - The RDF/XML document.

xmlBase - The base URI of the document or "".

Throws:

JenaException

read

public void read(Graph g,
                 java.io.Reader reader,
                 java.lang.String xmlBase)
          throws JenaException

Reads from reader, using base URI xmlbase, adding triples to graph. If xmlbase is "" then relative URIs may be added to graph.

Parameters:

g - A graph to add triples to.

reader - The RDF/XML document.

xmlBase - The base URI of the document or "".

Throws:

JenaException

read

public void read(Model m,
                 java.io.InputStream in,
                 java.lang.String xmlBase)
          throws JenaException

Reads from inputStream, using base URI xmlbase, adding triples to model. If xmlbase is "" then relative URIs may be added to model.

Specified by:

read in interface RDFReaderI

Parameters:

m - A model to add triples to.

in - The RDF/XML document stream.

xmlBase - The base URI of the document or "".

Throws:

JenaException

read

public void read(Graph g,
                 java.io.InputStream in,
                 java.lang.String xmlBase)

Reads from inputStream, using base URI xmlbase, adding triples to graph. If xmlbase is "" then relative URIs may be added to graph.

Parameters:

g - A graph to add triples to.

in - The RDF/XML document stream.

xmlBase - The base URI of the document or "".

setErrorHandler

public RDFErrorHandler setErrorHandler(RDFErrorHandler errHandler)

Change the error handler.

Note that errors of class ParseExceptioncan be promoted using the ParseException.promote()method. See ARP documentation for ErrorHandlerfor the details of error promotion.

Specified by:

setErrorHandler in interface RDFReaderI

Parameters:

errHandler - The new error handler.

Returns:

The old error handler.

setProperty

public java.lang.Object setProperty(java.lang.String str,
                                    java.lang.Object value)
                             throws JenaException

Change a property of the RDF or XML parser.

I do not believe that many of the XML features or properties are in fact useful for ARP users. The ARP properties allow fine-grained control over error reporting.

This interface can be used to set and get:

SAX2 features

See Xerces features . Value should be given as a String "true" or "false" or a Boolean.

SAX2 properties

See Xerces properties .

Xerces features

See Xerces features . Value should be given as a String "true" or "false" or a Boolean.

Xerces properties

See Xerces properties .

ARP properties

These are referred to either by their property name, (see below) or by an absolute URL of the form http://jena.hpl.hp.com/arp/properties/<PropertyName>. The value should be a String, an Integer or a Boolean depending on the property.
ARP property names and string values are case insensitive.

ARP Properties
Property Name	Description	Value class	Legal Values
error-mode	ARPOptions.setDefaultErrorMode() ARPOptions.setLaxErrorMode() ARPOptions.setStrictErrorMode() ARPOptions.setStrictErrorMode(int)	String	default lax strict strict-ignore strict-warning strict-error strict.error
embedding	ARPOptions.setEmbedding(boolean)	String or Boolean	true or false
ERR_<XXX> WARN_<XXX> IGN_<XXX>	ARPErrorNumbers Any of the error condition numbers listed. ARPOptions.setErrorMode(int, int)	String or Integer	EM_IGNORE EM_WARNING EM_ERROR EM_FATAL

Specified by:

setProperty in interface RDFReaderI

Parameters:

str - The property to set.

value - The new value; values of class String will be converted into appropriate classes. Values of class Boolean or Integer will be used for appropriate properties.

Returns:

The old value, or null if none, or old value is inaccesible.

Throws:

JenaException - For bad values.
