All Implemented Interfaces:

Enclosing class:

CocoonMarkupLanguage

public class CocoonMarkupLanguage.CocoonTransformerChainBuilderFilter
extends AbstractMarkupLanguage.TransformerChainBuilderFilter

This filter builds on the fly a chain of transformers. It extends the AbstractMarkupLanguage.TransformerChainBuilderFilter so it can add common markup language features such as:

• Looking for <?xml-logisheet href="..."?;> PI and <xsp:xml-logisheet location="..."> elements to register user defined logicsheets;
• Adding all the dependencies related to the pages as <xsp:dependency;>...</xsp:dependency;>
