public class PropagatorAction

extends org.apache.cocoon.acting.ServiceableAction

implements Configurable, ThreadSafe

This is the action used to propagate parameters into a store using an OutputModule. It simply propagates given expression. Additionaly it will make all propagated values available via returned Map.

Example configuration:

 <map:action type="...." name="...." logger="...">
   <output-module name="session-attr">
      <!-- optional configuration for output module -->
   </output-module>
   <store-empty-parameters>true</store-empty-parameters>
   <defaults>
     <default name="..." value="...."/>
     <default name="..." value="..."/>
   </defaults>
 </map:action>
 

Example use:

 <map:act type="session-propagator">
      <paramater name="example" value="{example}"/>
      <paramater name="example1" value="xxx"/>
      <parameter name="PropagatorAction:store-empty-parameters" value="true"/>
      <parameter name="PropagatorAction:output-module" value="session-attr"/>
 </map:act>
 

Configuration

output-module	Nested element configuring output to use. Name attribute holds output module hint.		XML	request-attr

defaults	Parent for default parameters to propagate.		XML
defaults/default	Name attribute holds parameter name, value attribute holds parameter value. Will be used when not set on use.		parameter

Parameters
