Custom invokers

General information about invokers

To add custom invoker you need to do:

1. Create class which implements interface Invoker<Q,R,E>

   public class PageVisitorInvoker implements Invoker<String, String, String> {

   
   
2. Create bean in XML file in the directory "suite/invokers/" with this class

   <!-- begin: following section is used for docu generation - invoker bean -->
   <beans xmlns="http://www.springframework.org/schema/beans"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:lang="http://www.springframework.org/schema/lang"
          xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang.xsd"
          default-lazy-init="true">
   
       <bean id="pageInvoker" class="${package}.invoker.PageVisitorInvoker"/>
   
   </beans>
   <!-- end: following section is used for docu generation - invoker bean -->

   
   
3. Create component invoker with type invoker-class and set attribute class with full class name of invoker

       <!-- begin: following section is used for docu generation - invoker usage -->
       <scenario id="pageScenario" xsi:type="scenario-query-pool">
           <query-distributor xsi:type="query-distributor-round-robin"/>
           <invoker xsi:type="invoker-class" class="${package}.invoker.PageVisitorInvoker"/>
       </scenario>
       <!-- end: following section is used for docu generation - invoker usage -->

   
   Note:
