Method Detail

getSystemId

public java.lang.String getSystemId()

Implements javax.xml.transform.sax.TemplatesHandler.getSystemId() Get the base ID (URI or system ID) from where relative URLs will be resolved.

Specified by:

getSystemId in interface TemplatesHandler

Returns:

The systemID that was set with setSystemId(String id)

setSystemId

public void setSystemId(java.lang.String id)

Implements javax.xml.transform.sax.TemplatesHandler.setSystemId() Get the base ID (URI or system ID) from where relative URLs will be resolved.

Specified by:

setSystemId in interface TemplatesHandler

Parameters:

id - Base URI for this stylesheet

setURIResolver

public void setURIResolver(URIResolver resolver)

Store URIResolver needed for Transformers.

getTemplates

public Templates getTemplates()

Implements javax.xml.transform.sax.TemplatesHandler.getTemplates() When a TemplatesHandler object is used as a ContentHandler or DocumentHandler for the parsing of transformation instructions, it creates a Templates object, which the caller can get once the SAX events have been completed.

Specified by:

getTemplates in interface TemplatesHandler

Returns:

The Templates object that was created during the SAX event process, or null if no Templates object has been created.

loadSource

public InputSource loadSource(java.lang.String href,
                              java.lang.String context,
                              XSLTC xsltc)

This method implements XSLTC's SourceLoader interface. It is used to glue a TrAX URIResolver to the XSLTC compiler's Input and Import classes.

Specified by:

loadSource in interface SourceLoader

Parameters:

href - The URI of the document to load

context - The URI of the currently loaded document

xsltc - The compiler that resuests the document

Returns:

An InputSource with the loaded document

startDocument

public void startDocument()

Re-initialize parser and forward SAX2 event.

Specified by:

startDocument in interface ContentHandler

See Also:

ContentHandler.endDocument()

endDocument

public void endDocument()
                 throws SAXException

Just forward SAX2 event to parser object.

Specified by:

endDocument in interface ContentHandler

Throws:

SAXException - Any SAX exception, possibly wrapping another exception.

See Also:

ContentHandler.startDocument()

startPrefixMapping

public void startPrefixMapping(java.lang.String prefix,
                               java.lang.String uri)

Just forward SAX2 event to parser object.

Specified by:

startPrefixMapping in interface ContentHandler

Parameters:

prefix - The Namespace prefix being declared. An empty string is used for the default element namespace, which has no prefix.

uri - The Namespace URI the prefix is mapped to.

See Also:

ContentHandler.endPrefixMapping(java.lang.String), ContentHandler.startElement(java.lang.String, java.lang.String, java.lang.String, org.xml.sax.Attributes)

endPrefixMapping

public void endPrefixMapping(java.lang.String prefix)

Just forward SAX2 event to parser object.

Specified by:

endPrefixMapping in interface ContentHandler

Parameters:

prefix - The prefix that was being mapping. This is the empty string when a default mapping scope ends.

See Also:

ContentHandler.startPrefixMapping(java.lang.String, java.lang.String), ContentHandler.endElement(java.lang.String, java.lang.String, java.lang.String)

startElement

public void startElement(java.lang.String uri,
                         java.lang.String localname,
