org.infohazard.maverick.ctl
Class FormBeanUser  

java.lang.Object
  org.infohazard.maverick.ctl.FormBeanUser

All Implemented Interfaces:

org.infohazard.maverick.flow.Controller, org.infohazard.maverick.flow.ControllerSingleton

---

public abstract class FormBeanUser

extends java.lang.Object

implements org.infohazard.maverick.flow.ControllerSingleton

FormBeanUser is a base class for singleton controllers which use external FormBeans rather than populating themselves. Since only one of these will exist for each command definition, it must be thread-safe. This Controller pattern is very similar to Struts Actions.

Method Summary
java.lang.String	go(org.infohazard.maverick.flow.ControllerContext cctx)           Executes this controller.
void	init(org.jdom.Element controllerNode)           If you want any custom behavior based on the content of the configuration file, this will be called once before the FormBeanUser is ever used.
protected abstract  java.lang.Object	makeFormBean(org.infohazard.maverick.flow.ControllerContext cctx)           This method will be called to produce a simple bean whose properties will be populated with the http request parameters.
protected  java.lang.String	perform(java.lang.Object formBean, org.infohazard.maverick.flow.ControllerContext cctx)           This method can be overriden to perform application logic.

Method Detail

init

public void init(org.jdom.Element controllerNode)
          throws org.infohazard.maverick.flow.ConfigException

If you want any custom behavior based on the content of the configuration file, this will be called once before the FormBeanUser is ever used.

Specified by:

init in interface org.infohazard.maverick.flow.ControllerSingleton

---

go

public final java.lang.String go(org.infohazard.maverick.flow.ControllerContext cctx)
                          throws javax.servlet.ServletException

Executes this controller. Override one of the other perform() methods to provide application logic.

Specified by:

go in interface org.infohazard.maverick.flow.Controller

---

perform

protected java.lang.String perform(java.lang.Object formBean,
                                   org.infohazard.maverick.flow.ControllerContext cctx)
                            throws java.lang.Exception

This method can be overriden to perform application logic. Override this method if you want the model to be something other than the formBean itself.

---

makeFormBean

protected abstract java.lang.Object makeFormBean(org.infohazard.maverick.flow.ControllerContext cctx)

This method will be called to produce a simple bean whose properties will be populated with the http request parameters. The parameters are useful for doing things like persisting beans across requests.
