Class SAXSource

java.lang.Object

javax.xml.transform.sax.SAXSource

All Implemented Interfaces:

Source

public class SAXSource
extends java.lang.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 SAXParserFactory.setNamespaceAware(boolean awareness) method.

Field Detail

FEATURE

public static final java.lang.String FEATURE

If TransformerFactory.getFeature(java.lang.String) returns true when passed this value as an argument, the Transformer supports Source input of this type.

Constructor Detail

SAXSource

public SAXSource()

Zero-argument default constructor. If this constructor is used, and no SAX source is set using setInputSource(InputSource inputSource) , then the Transformer will create an empty source InputSource using new InputSource().

See Also:

Transformer.transform(Source xmlSource, Result outputTarget)

SAXSource

public SAXSource(XMLReader reader,
         InputSource inputSource)

Create a SAXSource, using an XMLReader and a SAX InputSource. The Transformer or SAXTransformerFactory will set itself to be the reader's ContentHandler, and then will call reader.parse(inputSource).

Parameters:

reader - An XMLReader to be used for the parse.

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

SAXSource

public SAXSource(InputSource inputSource)

Create a SAXSource, using a SAX InputSource. The Transformer or SAXTransformerFactory creates a reader via XMLReaderFactory (if setXMLReader is not used), sets itself as the reader's ContentHandler, and calls reader.parse(inputSource).

Parameters:

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

Method Detail

setXMLReader

public void setXMLReader(XMLReader reader)

Set the XMLReader to be used for the Source.

Parameters:

reader - A valid XMLReader or XMLFilter reference.

getXMLReader

public XMLReader getXMLReader()

Get the XMLReader to be used for the Source.

Returns:

A valid XMLReader or XMLFilter reference, or null.

setInputSource

public void setInputSource(InputSource inputSource)

Set the SAX InputSource to be used for the Source.

Parameters:

inputSource - A valid InputSource reference.

getInputSource

public InputSource getInputSource()

Get the SAX InputSource to be used for the Source.

Returns:

A valid InputSource reference, or null.

setSystemId

public void setSystemId(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).

Specified by:

setSystemId in interface Source

Parameters:

systemId - The system identifier as a URI string.

getSystemId

public java.lang.String getSystemId()

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

Specified by:

getSystemId in interface Source

Returns:

Base URL for the Source, or null.

sourceToInputSource

public static InputSource sourceToInputSource(Source source)

Attempt to obtain a SAX InputSource object from a Source object.

Parameters:

source - Must be a non-null Source reference.

Returns:

An InputSource, or null if Source can not be converted.
