All Implemented Interfaces:

Component, LogEnabled, Serviceable, ThreadSafe, RendererAspect

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:

• Layout

Parameters

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

                  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
