Package net.sf.saxon.resource

Class ActiveSAXSource

java.lang.Object

javax.xml.transform.sax.SAXSource

net.sf.saxon.resource.ActiveSAXSource

All Implemented Interfaces:

Source, ActiveSource

public class ActiveSAXSource
extends SAXSource
implements ActiveSource

This class extends the standard SAXSource class by providing a deliver(Receiver, ParseOptions) method, meaning that Saxon can treat it just like any other ActiveSource implementation.

This makes it easier to extract code from the product that's specific to the Java platform (in particular, support for SAX APIs).

Constructor Details

ActiveSAXSource

public ActiveSAXSource(XMLReader parser,
 InputSource source)

ActiveSAXSource

public ActiveSAXSource(SAXSource source)
                throws IllegalArgumentException,
XPathException

Construct an ActiveSAXSource from a SAXSource

Parameters:

source - the input source object, whose properties are copied. The source must include a non-null XMLReader.

Throws:

IllegalArgumentException

XPathException

ActiveSAXSource

public ActiveSAXSource(InputSource inputSource,
 Configuration config)

Method Details

setParserPool

public void setParserPool(Consumer<XMLReader> parserPool)

Supply a mechanism to recycle the XMLReader after use

Parameters:

parserPool - a place to return the parser after parsing is complete

deliver

public void deliver(Receiver receiver,
 ParseOptions options)
             throws XPathException

Description copied from interface: ActiveSource

Deliver the content of the source to a supplied Receiver.

For many (but not all) implementations of Source, this method consumes the source and can therefore only be called once.

Specified by:

deliver in interface ActiveSource

Parameters:

receiver - the receiver to which events representing the parsed XML document will be sent

options - options for parsing the source

Throws:

XPathException - if parsing fails for any reason. The detailed diagnostics will have been sent to the error reporter.

configureParser

public static void configureParser(XMLReader parser)
                            throws XPathException

Configure a SAX parser to ensure it has the correct namespace properties set

Parameters:

parser - the parser to be configured

Throws:

XPathException - if the parser cannot be configured to the required settings (namespaces=true, namespace-prefixes=false). Note that the SAX specification requires every XMLReader to support these settings, so this error implies that the XMLReader is non-conformant; this is not uncommon in cases where the XMLReader is user-written.
