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.

LinkEncodingProcessor
public LinkEncodingProcessor()
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
