      javax.portlet.filter.EventResponseWrapper

All Implemented Interfaces:

EventResponse, PortletResponse, StateAwareResponse

public class EventResponseWrapper
extends PortletResponseWrapper
implements EventResponse

The EventResponseWrapper provides a convenient implementation of the EventResponse interface that can be subclassed by developers wishing to adapt the response. This class implements the Wrapper or Decorator pattern. Methods default to calling through to the wrapped response object.

Since:

2.0

Constructor Detail

EventResponseWrapper

public EventResponseWrapper(EventResponse response)

Creates an EventResponse adaptor wrapping the given response object.

Parameters:

response - the event response to wrap

Throws:

java.lang.IllegalArgumentException - if the response is null

Method Detail

setEvent

public void setEvent(javax.xml.namespace.QName name,
                     java.io.Serializable value)

The default behavior of this method is to call setEvent(name, value) on the wrapped response object.

Specified by:

setEvent in interface StateAwareResponse

Parameters:

name - the event name to publish, must not be null

value - the value of this event, must have a valid JAXB binding and be serializable, or null.

setPortletMode

public void setPortletMode(PortletMode portletMode)
                    throws PortletModeException

The default behavior of this method is to call setPortletMode(portletMode) on the wrapped response object.

Specified by:

setPortletMode in interface StateAwareResponse

Parameters:

portletMode - the new portlet mode

Throws:

PortletModeException - if the portlet cannot switch to this portlet mode, because the portlet or portal does not support it for this markup, or the current user is not allowed to switch to this portlet mode. To avoid this exception the portlet can check the allowed portlet modes with Request.isPortletModeAllowed().

setRenderParameter

public void setRenderParameter(java.lang.String key,
                               java.lang.String value)

The default behavior of this method is to call setRenderParameter(key, value) on the wrapped response object.

Specified by:

setRenderParameter in interface StateAwareResponse

Parameters:

key - key of the render parameter

value - value of the render parameter

setRenderParameter

public void setRenderParameter(java.lang.String key,
                               java.lang.String[] values)

The default behavior of this method is to call setRenderParameter(key, value) on the wrapped response object.

Specified by:

setRenderParameter in interface StateAwareResponse

Parameters:

key - key of the render parameter

values - values of the render parameter

setRenderParameters

public void setRenderParameters(java.util.Map<java.lang.String,java.lang.String[]> parameters)

The default behavior of this method is to call setRenderParameters(parameters) on the wrapped response object.

Specified by:

setRenderParameters in interface StateAwareResponse

Parameters:

parameters - Map containing parameter names for the render phase as keys and parameter values as map values. The keys in the parameter map must be of type String. The values in the parameter map must be of type String array (String[]).

setWindowState

public void setWindowState(WindowState windowState)
                    throws WindowStateException

Specified by:

setWindowState in interface StateAwareResponse

Parameters:

windowState - the new portlet window state

Throws:

WindowStateException - if the portlet cannot switch to the specified window state. To avoid this exception the portlet can check the allowed window states with Request.isWindowStateAllowed().
