org.apache.cocoon.transformation.pagination
Class Pagesheet

java.lang.Object
  org.xml.sax.helpers.DefaultHandler
      org.apache.cocoon.transformation.pagination.Pagesheet

All Implemented Interfaces:

Cloneable, ContentHandler, DTDHandler, EntityResolver, ErrorHandler, org.apache.cocoon.Modifiable

public class Pagesheet

extends DefaultHandler

implements Cloneable, org.apache.cocoon.Modifiable

Interprets the pagesheet rules to perform pagination.

 FIXME (SM): this code sucks! It was done to show the concept of
             rule driven pagination (which I find very nice) but
             it needs major refactoring in order to be sufficiently
             stable to allow any input to enter without breaking
             SAX well-formness. I currently don't have the time to make
             it any better (along with implementing the char-based rule
             that is mostly useful for text documents) but if you want
             to blast the code and rewrite it better, you'll make me happy :)
