## org.apache.jmeter.control
Class ModuleController

    java.lang.Object
      org.apache.jmeter.testelement.AbstractTestElement
          org.apache.jmeter.control.GenericController
              org.apache.jmeter.control.ModuleController

All Implemented Interfaces:
  Serializable, Cloneable, Controller, ReplaceableController, Searchable, TestElement, TestCompilerHelper

    public class ModuleController

extends GenericController
implements ReplaceableController

The goal of ModuleController is to add modularity to JMeter. The general idea is that web applications consist of small units of functionality (i.e. Logon, Create Account, Logoff...) which consist of requests that implement the functionality. These small units of functionality can be stored in SimpleControllers as modules that can be linked together quickly to form tests. ModuleController facilitates this by acting as a pointer to any controller that sits under the WorkBench. The controller and it's subelements will be substituted in place of the ModuleController at runtime. Config elements can be attached to the ModuleController to alter the functionality (which user logs in, which account is created, etc.) of the module.
