public class VelocityPortletControl

extends AbstractPortletControl

A Velocity based portlet control which implements all PortletState action

To use this control you need to define in your registry the following entry or similar:

   
     org.apache.jetspeed.portal.controls.VelocityPortletControl
     
     
       
       The standard Jetspeed boxed control
       url of image (icon)

Constructor Detail

VelocityPortletControl

public VelocityPortletControl()

Method Detail

isCacheable

public boolean isCacheable()

Disable content caching

Specified by:

isCacheable in interface Cacheable

Overrides:

isCacheable in class AbstractPortlet

Returns:

true Cachable
false Not cachable

getContent

public org.apache.ecs.ConcreteElement getContent(org.apache.turbine.util.RunData rundata)

Handles the content generation for this control using Velocity

Specified by:

getContent in interface Portlet

Overrides:

getContent in class AbstractPortletControl

Parameters:

rundata - the RunData for the request

buildContext

public void buildContext(org.apache.turbine.util.RunData rundata,
                         org.apache.velocity.context.Context context)

This method allows subclasses of the VelocityPortletControl to populate the context of this control before rendering by the template engine.

Parameters:

rundata - the RunData object for this request

context - the Context used by the template

buildActionList

protected java.util.List buildActionList(org.apache.turbine.util.RunData rundata,
                                         Portlet portlet)

Builds a list of possible window actions for this portlet instance. For best results, the portlet should also implement the PortletState interface.

Parameters:

rundata - the request RunData

Returns:

a list of ordered PortletAction objects describing the the actions available for this portlet

createActionList

protected java.util.List createActionList(java.util.List actions,
                                          JetspeedRunData rundata,
                                          Portlet portlet)

getAction

protected static java.lang.String getAction(java.lang.String name)

Transforms an Action name in Turbine valid action name, by adding a controls package prefix and capitalizing the first letter of the name.
