VelocityActionEvent (Apache Turbine 5.1 API)

java.lang.Object
- org.apache.turbine.modules.ActionEvent
- - org.apache.turbine.util.velocity.VelocityActionEvent

All Implemented Interfaces:

Action, Assembler

Direct Known Subclasses:

VelocityAction
```
public abstract class VelocityActionEvent
extends ActionEvent
```
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.

```
    Provides a means of initializing the module.
    
    Throws:
    
    Exception - a generic exception.
  - doPerform
```
public void doPerform(PipelineData pipelineData)
               throws Exception
```
    This overrides the default Action.doPerform() to execute the doEvent() method. If that fails, then it will execute the doPerform() method instead.
    
    Specified by:
    
    doPerform in interface Action
    
    Overrides:
    
    doPerform in class ActionEvent
    
    Parameters:
    
    pipelineData - A Turbine RunData object.
    
    Throws:
    
    Exception - a generic exception.
