public interface BridgeWriteBehindResponse
The BridgeWriteBehindResponse
interface defines the api the bridge relies
on to acquire the buffered JSP output from the response(Wrapper) used to handle the Faces
implementation dependent writeBehindResponse methodlogy/interface.
Note: the Portlet 1.0 Bridge relied on Portlet 1.0 which didn't support response wrappers. In that version the writeBehindResponse behavior is provided in a Servlet ResponseWrapper inserted in a Servlet filter set up to be called on included JSPs. In Portlet 2.0 Bridge this behavior can now be implemented directly in a Portlet ResponseWrapper which can then be registered for use with the bridge. So that the bridge recognizes and use this support, such wrappers must implement this interface.
Implementations must be one of the Portlet 2.0 ResponseWrappers
and have a null constructor that utilizes
FacesContext.getCurrentInstance().getExternalContext().getResponse()
to acquire the response to be wrapped.
Method Summary | |
---|---|
void |
flushMarkupToWrappedResponse()
Called by the bridge after dispatching to flush the current buffered content to the wrapped response (this could be a Servlet or Portlet response). |
byte[] |
getBytes()
Called by the bridge after dispatching is complete to acquire the AfterJSPContent when the response has been written as bytes. |
char[] |
getChars()
Called by the bridge after dispatching is complete to acquire the AfterJSPContent when the response has been written as characters. |
boolean |
hasFacesWriteBehindMarkup()
Called by the bridge to detect whether this response actively participated in the Faces writeBehind support and hence has data that should be written after the View is rendered. |
boolean |
isBytes()
Called by the bridge after dispatching is complete to determine whether the JSP AfterViewContent was written as bytes (written via an OutputStream |
boolean |
isChars()
Called by the bridge after dispatching is complete to determine whether the JSP AfterViewContent was written as chars (written via a PrintWriter |

java.io.IOException
- if content cannot be writtenboolean hasFacesWriteBehindMarkup()
true
if the Faces write behind implementation specific flush api has been called
on this response, otherwise false
