com.hp.hpl.jena.rdf.arp.ARP

Another RDF Parser. To load an RDF file:

Create an ARP.
Set its handlers, by calling the {@link #getHandlers}method, and then.

Setting the statement handler.
Optionally setting the other handlers.

Call a load method.

Xerces is used for parsing the XML. The SAXEvents generated by Xerces are then analysed as RDF by ARP. Errors may occur in either the XML or the RDF part, see {@link ARPHandlers#setErrorHandler} for detailsof how to distinguish between them.

For very large files, ARP does not use any additional memory except when either the {@link ExtendedHandler#discardNodesWithNodeID}returns false or when the {@link AResource#setUserData} method has beenused. In these cases ARP needs to remember the rdf:nodeID usage through the file life time.

See ARP documentation for more information.
