public final class ParameterAspect
extends AbstractAspect

Add layout parameter to resulting XML stream so that they can be picked up later from a stylesheet for example. When passing parameters to the XSLTAspect consider it's ability to set XSL parameters directly.

Example XML:

   <parameter name1="value1" name2="value2" ... >
     <!-- output from following renderers -->
   </parameter>
 

Applicable to:

Parameters

tag-nameName of tag holding key-value pairs as attributes. String"parameter"

Method Detail

toSAX

public void toSAX(RendererAspectContext context,
                  Layout layout,
                  PortalService service,
                  ContentHandler contenthandler)
           throws SAXException
Description copied from interface: RendererAspect
Stream out raw layout

Specified by:
toSAX in interface RendererAspect
Overrides:
toSAX in class AbstractAspect
Throws:
SAXException

prepareConfiguration

public Object prepareConfiguration(Parameters configuration)
                            throws ParameterException
Description copied from interface: RendererAspect
Compile the configuration. A renderer aspect can "compile" the configuration in order to increase performance. If the renderer does not want to compile it should simply return the configuration. The "compiled" configuration is passed to the RendererAspect.getAspectDescriptions(Object) method and is available during streaming via the context object. This method can also be used for validation the configuration.

Specified by:
prepareConfiguration in interface RendererAspect
Overrides:
prepareConfiguration in class AbstractAspect
Throws:
ParameterException
