Class SAXSource
- java.lang.Object
-
- javax.xml.transform.sax.SAXSource
- All Implemented Interfaces:
Source
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 SAXParserFactory.setNamespaceAware(boolean awareness)
method.

- 1.4

FEATURE
public static final 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()
.
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 (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(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 interfaceSource
- Parameters:
-
systemId
- The system identifier as a URI string.
getSystemId
public String getSystemId()
Get the base ID (URI or system ID) from where URIs will be resolved.
- Specified by:
-
getSystemId
in interfaceSource
- Returns:
- Base URL for the
Source
, ornull
.
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.
isEmpty
public boolean isEmpty()
Indicates whether the SAXSource
object is empty. Empty is defined as follows:
- if the system identifier and
InputSource
arenull
; - if the system identifier is
null
, and theInputSource
is empty.
