Method Detail

create

public static SAX2Model create(String base,
               Model m)
                        throws SAXParseException

Factory method to create a new SAX2Model.

Parameters:

base - The retrieval URL, or the base URI to be used while parsing.

m - A Jena Model in which to put the triples, this can be null. If it is null, then use SAX2RDF.getHandlers() or SAX2RDF.setHandlersWith(com.hp.hpl.jena.rdf.arp.ARPHandlers) to provide a StatementHandler, and usually an ErrorHandler

Returns:

A new SAX2Model

Throws:

SAXParseException - On a.error error during setup, maybe malformed base URI

create

public static SAX2Model create(String base,
               Model m,
               String lang)
                        throws SAXParseException

Factory method to create a new SAX2Model. This is particularly intended for when parsing a non-root element within an XML document. In which case the application needs to find this value in the outer context. Optionally, namespace prefixes can be passed from the outer context using startPrefixMapping(java.lang.String, java.lang.String).

Parameters:

base - The retrieval URL, or the base URI to be used while parsing.

m - A Jena Model in which to put the triples, this can be null. If it is null, then use SAX2RDF.getHandlers() or SAX2RDF.setHandlersWith(com.hp.hpl.jena.rdf.arp.ARPHandlers) to provide a StatementHandler, and usually an ErrorHandler

lang - The current value of xml:lang when parsing starts, usually "".

Returns:

A new SAX2Model

Throws:

SAXParseException - On a.error error during setup, maybe malformed base URI

startPrefixMapping

public void startPrefixMapping(String prefix,
                      String uri)
                        throws SAXParseException

Begin the scope of a prefix-URI Namespace mapping.

This is passed to any NamespaceHandler associated with this parser. It can be called before the initial startElement event, or other events associated with the elements being processed. When building a Jena Model, it is not required to match this with corresponding endPrefixMapping events. Other NamespaceHandlers may be fussier. When building a Jena Model, the prefix bindings are remembered with the Model, and may be used in some output routines. It is permitted to not call this method for prefixes declared in the outer context, in which case, any output routine will need to use a gensym for such namespaces.

Specified by:

startPrefixMapping in interface ContentHandler

Overrides:

startPrefixMapping in class SAX2RDF

Parameters:

prefix - The Namespace prefix being declared.

uri - The Namespace URI the prefix is mapped to.

Throws:

SAXParseException

close

public void close()

Overrides:

close in class com.hp.hpl.jena.rdf.arp.impl.SAX2RDFImpl

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.

Parameters:

errHandler - The new error handler.

Returns:

The old error handler.

setProperty

public Object setProperty(String str,
                 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

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.
