## javax.portlet.filter
Class EventResponseWrapper

    java.lang.Object
      javax.portlet.filter.PortletResponseWrapper
          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
    `IllegalArgumentException` - if the response is `null`

Method Detail

### setEvent

    public void setEvent(QName name,
                         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(String key,
                                   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(String key,
                                   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(Map<String,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

  The default behavior of this method is to call `setWindowState(windowState)` on the wrapped response object.

  Specified by:
    `setWindowState` in interface `StateAwareResponse`
  Parameters
    `windowState` - the new portlet window state
