Constructor Detail

TrAXFilter

public TrAXFilter(javax.xml.transform.Templates templates)
           throws javax.xml.transform.TransformerConfigurationException

Construct an empty XML filter, with no parent.

This filter will have no parent: you must assign a parent before you start a parse or do any configuration with setFeature or setProperty.

Throws:

javax.xml.transform.TransformerConfigurationException

See Also:

XMLReader.setFeature(java.lang.String, boolean), XMLReader.setProperty(java.lang.String, java.lang.Object)

Method Detail

getTransformer

public TransformerImpl getTransformer()

Return the Transformer object used for this XML filter.

setParent

public void setParent(org.xml.sax.XMLReader parent)

Set the parent reader.

This is the XMLReader from which this filter will obtain its events and to which it will pass its configuration requests. The parent may itself be another filter.

If there is no parent reader set, any attempt to parse or to set or get a feature or property will fail.

Specified by:

setParent in interface org.xml.sax.XMLFilter

Overrides:

setParent in class org.xml.sax.helpers.XMLFilterImpl

Parameters:

parent - The parent XML reader.

Throws:

java.lang.NullPointerException - If the parent is null.

parse

public void parse(org.xml.sax.InputSource input)
           throws org.xml.sax.SAXException,
                  java.io.IOException

Parse a document.

Specified by:

parse in interface org.xml.sax.XMLReader

Overrides:

parse in class org.xml.sax.helpers.XMLFilterImpl

Parameters:

input - The input source for the document entity.

Throws:

org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

java.io.IOException - An IO exception from the parser, possibly from a byte stream or character stream supplied by the application.

See Also:

XMLReader.parse(org.xml.sax.InputSource)

parse

public void parse(java.lang.String systemId)
           throws org.xml.sax.SAXException,
                  java.io.IOException

Parse a document.

Specified by:

parse in interface org.xml.sax.XMLReader

Overrides:

parse in class org.xml.sax.helpers.XMLFilterImpl

Parameters:

systemId - The system identifier as a fully-qualified URI.

Throws:

org.xml.sax.SAXException - Any SAX exception, possibly wrapping another exception.

java.io.IOException - An IO exception from the parser, possibly from a byte stream or character stream supplied by the application.

See Also:

XMLReader.parse(java.lang.String)

setupParse

private void setupParse()

Set up before a parse.

Before every parse, check whether the parent is non-null, and re-register the filter for all of the events.

setContentHandler

public void setContentHandler(org.xml.sax.ContentHandler handler)

Set the content event handler.

Specified by:

setContentHandler in interface org.xml.sax.XMLReader

Overrides:

setContentHandler in class org.xml.sax.helpers.XMLFilterImpl

Parameters:

handler - The new content handler.

Throws:

java.lang.NullPointerException - If the handler is null.

See Also:

XMLReader.setContentHandler(org.xml.sax.ContentHandler)

setErrorListener

public void setErrorListener(javax.xml.transform.ErrorListener handler)
