JenaReader

public JenaReader()

Creates new JenaReader

Method Detail

useMe

public static void useMe(Model m)

Sets the reader for the languages RDF/XML and RDF/XML-ABBREV to be JenaReader.

Parameters:

m - The Model on which to set the reader properties.

read

public void read(Model model,
                 java.lang.String url)
          throws RDFException

Description copied from interface: RDFReader

Read serialized RDF from a url and add the statements to a model.

Specified by:

read in interface RDFReader

Following copied from interface: com.hp.hpl.mesa.rdf.jena.model.RDFReader

Parameters:

model - the model to which statements should be added

url - the url, as a string, from which the serialized RDF should be read.

translate

public static Literal translate(ALiteral lit)

Converts an ARP literal into a Jena Literal.

Parameters:

lit - The ARP literal.

Returns:

The Jena Literal.

translate

public static Resource translate(AResource r)

Converts an ARP resource into a Jena resource.

Parameters:

r - The ARP resource.

Returns:

The Jena resource.

translatePred

public static Property translatePred(AResource r)
                              throws RDFException

Converts an ARP resource into a Jena property.

Parameters:

r - The ARP resource.

Returns:

The Jena property.

Throws:

RDFException - If r is anonymous, or similarly ill-formed.

read

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

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 RDFReader

Parameters:

model - A model to add triples to.

reader - The RDF/XML document.

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

read

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

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

Parameters:

model - A model to add triples to.

reader - The RDF/XML document.

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

setErrorHandler

public RDFErrorHandler setErrorHandler(RDFErrorHandler errHandler)

Change the error handler.

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

Specified by:

setErrorHandler in interface RDFReader

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 RDFException

Change a property of the RDF or XML parser.

This method is untested.

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	ARP.setDefaultErrorMode() ARP.setLaxErrorMode() ARP.setStrictErrorMode() ARP.setStrictErrorMode(int)	String	default lax strict strict-ignore strict-warning strict-error strict-fatal
embedding	ARP.setEmbedding(boolean)	String or Boolean	true or false
ERR_<XXX> WARN_<XXX> IGN_<XXX>	ARPErrorNumbers Any of the error condition numbers listed. ARP.setErrorMode(int, int)	String or Integer	EM_IGNORE EM_WARNING EM_ERROR EM_FATAL

Specified by:

setProperty in interface RDFReader

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:

RDFException - For bad values.

memModel

public static Model memModel()

Create a instance of ModelMem() and set it to use JenaReader as its default reader.

Returns:

A new in-memory Jena model.
