[hide private]

init(self, application, applicationServlet=None)
(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Overrides: object.__init__

Deprecated: use CommunicationManager instead

handleFileUpload(self, request, response, applicationServlet)

source code

Handles file upload request submitted via Upload component.

See Also: getStreamVariableTargetUrl @raise IOException: @raise InvalidUIDLSecurityKeyException:

handleUidlRequest(self, request, response, applicationServlet, window)

source code

Handles UIDL request.

Parameters:

request
response
applicationServlet
window - target window of the UIDL request, can be null if window not found

Raises:

IOException
ServletException

getApplicationWindow(self, request, applicationServlet, application, assumedWindow)

source code

Gets the existing application or creates a new one. Get a window within an application based on the requested URI.

Parameters:

request - the HTTP Request.
application - the Application to query for window.
assumedWindow - if the window has been already resolved once, this parameter must contain the window.

Returns:

Window matching the given URI or null if not found.

Raises:

ServletException - if an exception has occurred that interferes with the servlet's normal operation.

handleURI(self, window, request, response, applicationServlet)

source code

Calls the Window URI handler for a request and returns the DownloadStream returned by the handler.

If the window is the main window of an application, the deprecated Application.handleURI is called first to handle ApplicationResources and the window handler is only called if it returns None.

Parameters:
