Class ARPHandlers

  • public class ARPHandlers
extends java.lang.Object
    The interface to set the various handlers on ARP. User defined implementations of this interface are not supported. This is a class rather than an interface to have better backward compatibility with earlier versions, however constructing instances of this class is deprecated.

    • Method Detail

      • createNewHandlers

        public static ARPHandlers createNewHandlers()
        Internal use only

      • setExtendedHandler

        public ExtendedHandler setExtendedHandler​(ExtendedHandler sh)
        Sets the ExtendedHandler that provides the callback mechanism for bnodes as they leave scope, and for the start and end of rdf:RDF elements.

        See note about large files in ARP class documentation.

        Parameters:
        sh - The handler to use.
        Returns:
        The old handler.

      • setNamespaceHandler

        public NamespaceHandler setNamespaceHandler​(NamespaceHandler sh)
        Sets the NamespaceHandler that provides the callback mechanism for XML namespace declarations.
        Parameters:
        sh - The handler to use.
        Returns:
        The old handler.

      • setStatementHandler

        public StatementHandler setStatementHandler​(StatementHandler sh)
        Sets the StatementHandler that provides the callback mechanism for each triple in the file.
        Parameters:
        sh - The statement handler to use.
        Returns:
        The old statement handler.

      • setErrorHandler

        public org.xml.sax.ErrorHandler setErrorHandler​(org.xml.sax.ErrorHandler eh)
        Sets the error handler, for both XML and RDF parse errors. XML errors are reported by Xerces, as instances of SAXParseException; the RDF errors are reported from ARP as instances of ParseException. Code that needs to distingusih between them may look like: 
            void error( SAXParseException e ) throws SAXException {
      if ( e instanceof com.hp.hpl.jena.rdf.arp.ParseException ) {
           ...
      } else {
           ...
      }
    }

        See the ARP documentation for ErrorHandler for details of the ErrorHandler semantics (in particular how to upgrade a warning to an error, and an error to a.errorError).

        The Xerces/SAX documentation for ErrorHandler is available on the web.

        Parameters:
        eh - The error handler to use.
        Returns:
        The previous error handler.
