Cocoon API: Class LinkEncodingProcessor

org.apache.cocoon.processor
Class LinkEncodingProcessor

java.lang.Object
  |
  +--org.apache.cocoon.processor.LinkEncodingProcessor
All Implemented Interfaces:
Actor, Changeable, Processor, Status

public class LinkEncodingProcessor
extends java.lang.Object
implements Processor, Status

This class implements a LinkEncodingProcessor which encodes all URLs found in attributes specified by a Predicate. It is useful for use with cookie-less clients. You could use Xalan extension functions instead, but this is probably easier and faster, and doesn't require the use of Xalan-specific features in your stylesheet.

Constructor Detail

LinkEncodingProcessor

public LinkEncodingProcessor()
Method Detail

init

public void init(Director director)
Description copied from interface: Actor
Initialize the actor by indicating their director.
Specified by:
init in interface Actor

process

public org.w3c.dom.Document process(org.w3c.dom.Document document,
                                    java.util.Dictionary parameters)
                             throws java.lang.Exception
Description copied from interface: Processor
Process the DOM tree. The returned tree is allowed to be either a copy or the modified input tree.
Specified by:
process in interface Processor

recurse

protected void recurse(org.w3c.dom.Element e,
                       Predicate linkPredicate,
                       javax.servlet.http.HttpServletResponse response)

getStatus

public java.lang.String getStatus()
Description copied from interface: Status
Returns information about the status of the implementing class. Note: this is use instead of the usual toString() method because some of these methods are declared final in some classes in JDK 1.1.
Specified by:
getStatus in interface Status

hasChanged

public boolean hasChanged(java.lang.Object x)
Description copied from interface: Changeable
Returns false if the requested resource hasn't changed, true otherwise. This method is called by the cache system to ensure the validity of the cached response. It is the producer responsibility to provide the fastest possible implementation of this method or, whether this is not possible and the costs of the change evaluation is comparable to the production costs, to return true directly with no further delay, thus reducing the evaluation overhead to a minimum. This method is guaranteed to be called after at least a single call to any production methods getStream or getDocument. The context is the trigger of the changeable point and may differ between implementations.
Specified by:
hasChanged in interface Changeable
