Method Detail

handleXML

public void handleXML(RendererContext context,
                      org.w3c.dom.Document doc,
                      java.lang.String ns)
               throws java.lang.Exception

Handle an external xml document inside a Foreign Object Area.

This may throw an exception if for some reason it cannot be handled. The caller is expected to deal with this exception.

The implementation may convert the XML document internally to another XML dialect (SVG, for example) and call renderXML() on the AbstractRenderer again (which can be retrieved through the RendererContext).

Specified by:
handleXML in interface XMLHandler
Parameters:
context - The RendererContext (contains the user agent)
doc - A DOM containing the foreign object to be processed
ns - The Namespace of the foreign object
Throws:
java.lang.Exception - If an error occurs during processing.

supportsRenderer

public boolean supportsRenderer(Renderer renderer)
Checks if this XMLHandler supports handling an XML namespace for a particular renderer.

Specified by:
supportsRenderer in interface XMLHandler
Parameters:
renderer - the renderer for which to check.
Returns:
true if this XML handler supports a particular renderer

getNamespace

public java.lang.String getNamespace()

Specified by:
getNamespace in interface XMLHandler
Returns:
the XML namespace for the XML dialect this XMLHandler supports, null if all XML content is handled by this instance.
