public class CustomJXPathBindingBuilder
extends JXPathBindingBuilderBase

CustomJXPathBindingBuilder provides a helper class for the Factory implemented in JXPathBindingManager that helps construct the actual CustomJXPathBinding out of the configuration in the provided configElement which looks like one of the following:

1. No additional configuration requirements:

 <fb:custom id="widget-id" path="xpath expression"
     class="your.package.CustomBindingX" />
 

2. With custom configuration requirements:

 <fb:custom id="widget-id" path="xpath expression"
     builderclass="your.package.CustomBindingXBuilder"
     factorymethod="makeBinding"
 >
   <fb:config custom-atts="someValue">
     <!-- in here come the nested custom elements (recommended in own namespace)
             that make up the custom config -->
   </fb:config>
 </fb:context>
