SAXSource

public class SAXSource extends Object implements Source

Acts as an holder for SAX-style Source.

Note that XSLT requires namespace support. Attempting to transform an input source that is not generated with a namespace-aware parser may result in errors. Parsers can be made namespace aware by calling the {@link javax.xml.parsers.SAXParserFactory#setNamespaceAware(boolean awareness)} method.

Fields Summary
public static final String
FEATURE
If {@link javax.xml.transform.TransformerFactory#getFeature} returns true when passed this value as an argument, the Transformer supports Source input of this type.
private XMLReader
reader
The XMLReader to be used for the source tree input. May be null.
private InputSource
inputSource

The SAX InputSource to be used for the source tree input. Should not be null.

Constructors Summary
public SAXSource()

Zero-argument default constructor. If this constructor is used, and no SAX source is set using {@link #setInputSource(InputSource inputSource)} , then the Transformer will create an empty source {@link org.xml.sax.InputSource} using {@link org.xml.sax.InputSource#InputSource() new InputSource()}.

see
javax.xml.transform.Transformer#transform(Source xmlSource, Result outputTarget)
public SAXSource(XMLReader reader, InputSource inputSource)
Create a SAXSource, using an {@link org.xml.sax.XMLReader} and a SAX InputSource. The {@link javax.xml.transform.Transformer} or {@link javax.xml.transform.sax.SAXTransformerFactory} will set itself to be the reader's {@link org.xml.sax.ContentHandler}, and then will call reader.parse(inputSource).

param
reader An XMLReader to be used for the parse.
param
inputSource A SAX input source reference that must be non-null and that will be passed to the reader parse method.

        this.reader      = reader;
        this.inputSource = inputSource;
public SAXSource(InputSource inputSource)
Create a SAXSource, using a SAX InputSource. The {@link javax.xml.transform.Transformer} or {@link javax.xml.transform.sax.SAXTransformerFactory} creates a reader via {@link org.xml.sax.helpers.XMLReaderFactory} (if setXMLReader is not used), sets itself as the reader's {@link org.xml.sax.ContentHandler}, and calls reader.parse(inputSource).

param
inputSource An input source reference that must be non-null and that will be passed to the parse method of the reader.

        this.inputSource = inputSource;
Methods Summary
public org.xml.sax.InputSourcegetInputSource()
Get the SAX InputSource to be used for the Source.

return
A valid InputSource reference, or null.

        return inputSource;
public java.lang.StringgetSystemId()

Get the base ID (URI or system ID) from where URIs will be resolved.

return
Base URL for the Source, or null.


        if (inputSource == null) {
            return null;
        } else {
            return inputSource.getSystemId();
        }
public org.xml.sax.XMLReadergetXMLReader()
Get the XMLReader to be used for the Source.

return
A valid XMLReader or XMLFilter reference, or null.

        return reader;
public voidsetInputSource(org.xml.sax.InputSource inputSource)
Set the SAX InputSource to be used for the Source.

param
inputSource A valid InputSource reference.

        this.inputSource = inputSource;
public voidsetSystemId(java.lang.String systemId)
Set the system identifier for this Source. If an input source has already been set, it will set the system ID or that input source, otherwise it will create a new input source.

The system identifier is optional if there is a byte stream or a character stream, but it is still useful to provide one, since the application can use it to resolve relative URIs and can include it in error messages and warnings (the parser will attempt to open a connection to the URI only if no byte stream or character stream is specified).

param
systemId The system identifier as a URI string.


        if (null == inputSource) {
            inputSource = new InputSource(systemId);
        } else {
            inputSource.setSystemId(systemId);
        }
public voidsetXMLReader(org.xml.sax.XMLReader reader)
Set the XMLReader to be used for the Source.

param
reader A valid XMLReader or XMLFilter reference.

        this.reader = reader;
public static org.xml.sax.InputSourcesourceToInputSource(javax.xml.transform.Source source)
Attempt to obtain a SAX InputSource object from a Source object.

param
source Must be a non-null Source reference.
return
An InputSource, or null if Source can not be converted.


        if (source instanceof SAXSource) {
            return ((SAXSource) source).getInputSource();
        } else if (source instanceof StreamSource) {
            StreamSource ss      = (StreamSource) source;
            InputSource  isource = new InputSource(ss.getSystemId());

            isource.setByteStream(ss.getInputStream());
            isource.setCharacterStream(ss.getReader());
            isource.setPublicId(ss.getPublicId());

            return isource;
        } else {
            return null;
        }
