Class FilterMediatorFactory

java.lang.Object
  org.apache.synapse.config.xml.AbstractMediatorFactory
      org.apache.synapse.config.xml.AbstractListMediatorFactory
          org.apache.synapse.config.xml.FilterMediatorFactory

All Implemented Interfaces:

MediatorFactory

public class FilterMediatorFactory
extends AbstractListMediatorFactory

Creates a filter mediator instance with the default behavior

 <filter (source="xpath" regex="string") | xpath="xpath">
   mediator+
 </filter>
 

or if the filter medaitor needs to support the else behavior as well (i.e. a set of mediators to be executed when the filter evaluates to false).

 <filter (source="xpath" regex="string") | xpath="xpath">
   <then [sequence="string"]>
      mediator+
   </then>
   <else [sequence="string"]>
      mediator+
   </else>
 </filter>
