org.apache.turbine.util.velocity .VelocityActionEvent

All known Subclasses:   org.apache.turbine.modules.actions .VelocityAction,
VelocityActionEvent
abstract public class VelocityActionEvent extends ActionEvent (Code)
If you are using VelocitySite stuff, then your Action's should extend this class instead of extending the ActionEvent class. The difference between this class and the ActionEvent class is that this class will first attempt to execute one of your doMethod's with a constructor like this:
doEvent(RunData data, Context context)

It gets the context from the TemplateInfo.getTemplateContext() method. If it can't find a method like that, then it will try to execute the method without the Context in it.

Method Summary
abstract public void doPerform(RunData data)
     You need to implement this in your classes that extend this class.
public void executeEvents(RunData data, Context context)
     This method should be called to execute the event based system.
protected void perform(RunData data)
     This overrides the default Action.perform() to execute the doEvent() method.

Method Detail
doPerform
abstract public void doPerform(RunData data) throws Exception(Code)
You need to implement this in your classes that extend this class.
Parameters:
  data - A Turbine RunData object.
exception:
  Exception - a generic exception.

executeEvents
public void executeEvents(RunData data, Context context) throws Exception(Code)
This method should be called to execute the event based system.
Parameters:
  data - A Turbine RunData object.
Parameters:
  context - Velocity context information.
exception:
  Exception - a generic exception.

perform
protected void perform(RunData data) throws Exception(Code)
This overrides the default Action.perform() to execute the doEvent() method. If that fails, then it will execute the doPerform() method instead.
Parameters:
  data - A Turbine RunData object.
exception:
  Exception - a generic exception.
