All Implemented Interfaces:

Poolable, Recyclable, LogEnabled, XMLPipe, XMLProducer, XMLConsumer, ContentHandler, LexicalHandler

Direct Known Subclasses:

WoodyTemplateTransformer

public class EffectWidgetReplacingPipe
extends EffectPipe

The basic operation of this Pipe is that it replaces wt:widget (in the Constants.WT_NS namespace) tags (having an id attribute) by the XML representation of the corresponding widget instance.

These XML fragments (normally all in the "Woody Instance" namespace), can then be translated to a HTML presentation by an XSL. This XSL will then only have to style individual widget, and will not need to do the whole page layout.

For more information about the supported tags and their function, see the user documentation for the woody template transformer.
