public class AddPortletRequest
extends RenderPortletRequestBase<String>

Sent to the portal (server) if a new portlet instance of a given type should be added to the portal page. The portal server usually responds with a RenderPortlet event that has as payload the HTML that displays the portlet on the portal page.

Properties may be passed with the event. The interpretation of the properties is completely dependent on the handling portlet. It is recommended to use Strings as keys and JDK types as values. This avoids classpath dependencies on the portlet that is to be added.

The event’s result is the portlet id of the new portlet instance.

Constructor Detail

AddPortletRequest

public AddPortletRequest(RenderSupport renderSupport,
                         String portletType,
                         List<Portlet.RenderMode> renderModes)

Creates a new event.

Parameters:

renderSupport - the render support

portletType - the type of the portlet

renderModes - the render modes

AddPortletRequest

public AddPortletRequest(RenderSupport renderSupport,
                         String portletType,
                         List<Portlet.RenderMode> renderModes,
                         Map<?,?> properties)

Creates a new event.

Parameters:

renderSupport - the render support

portletType - the type of the portlet

renderModes - the render modes

properties - optional values for properties of the portlet instance

Method Detail

setForeground

public AddPortletRequest setForeground(boolean foreground)

Determines if the portlet will be put in the foreground. Defaults to true for added portlets as they are most likely supposed to be seen.

Parameters:

foreground - the foreground

Returns:

the event for easy chaining

portletType

public String portletType()

Returns the portlet type

Returns:

the portlet type

properties

public Map<Object,Object> properties()

Returns the properties. Every event returns a mutable map, thus allowing event handlers to modify the map even if none was passed to the constructor.

addProperty

public AddPortletRequest addProperty(Object key,
                                     Object value)

Convenience method for adding properties one-by-one.

Parameters:

key - the property key

value - the property value

Returns:

the event for easy chaining

ifPresent

public AddPortletRequest ifPresent(Object key,
                                   BiConsumer<Object,Object> action)

Convenience method that performs the given action if a property with the given key exists.

Parameters:

key - the property key

action - the action to perform

isForeground

public boolean isForeground()

Description copied from class: RenderPortletRequestBase

Indicates if portlet is to be put in foreground.

Specified by:

isForeground in class RenderPortletRequestBase<String>

Returns:

the result
