Method Detail

handleXML

public void handleXML(RendererContext context,
             Document doc,
             String ns)
               throws 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

Overrides:

handleXML in class AbstractGenericSVGHandler

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:

Exception - If an error occurs during processing.

renderSVGDocument

protected void renderSVGDocument(RendererContext rendererContext,
                     Document doc)
                          throws IOException

Render the SVG document.

Overrides:

renderSVGDocument in class AbstractGenericSVGHandler

Parameters:

rendererContext - the renderer context

doc - the SVG document

Throws:

IOException - In case of an I/O error while painting the image

createBridgeContext

public static org.apache.batik.bridge.BridgeContext createBridgeContext(FOUserAgent userAgent,
                                                        AFPGraphics2D g2d)

Parameters:

userAgent - a user agent instance

g2d - a graphics context

Returns:

a bridge context

supportsRenderer

public boolean supportsRenderer(Renderer renderer)

Checks if this XMLHandler supports handling an XML namespace for a particular renderer.

Parameters:

renderer - the renderer for which to check.

Returns:

true if this XML handler supports a particular renderer

updateRendererContext

protected void updateRendererContext(RendererContext context)

Override this method to update the renderer context if it needs special settings for certain conditions.

Overrides:

updateRendererContext in class AbstractGenericSVGHandler

Parameters:

context - the renderer context
