                            java.lang.String name)

Removes the attribute with the given name.

Parameters:

request - the current request

name - the name of the attribute to remove

setAttribute

public void setAttribute(Request request,
                         java.lang.String name,

getSessionId

public java.lang.String getSessionId(Request request,
                                     boolean create)

Get the session id for the provided request. If create is false and the creation of the actual session is deferred, this method should return null to reflect it doesn't have one.

Parameters:

request - The request

create - Whether to create an actual session (typically an instance of HttpSession) when not already done so

Returns:

The session id for the provided request, possibly null if create is false and the creation of the actual session was deferred

lookup

public Session lookup(Request request)

Retrieves the session for the provided request from this facade.

This method should return null if it is not bound yet, so that Wicket can recognize that it should create a session and call bind(Request, Session) right after that.

Parameters:

request - The current request

Returns:

The session for the provided request or null if the session was not bound

bind

public void bind(Request request,
                 Session newSession)

Adds the provided new session to this facade using the provided request.

Parameters:

request - The request that triggered making a new session

newSession - The new session

unbind

public void unbind(java.lang.String sessionId)

Removes a session from this facade

Parameters:

sessionId - The id of the session that must be unbound.

onBeginRequest

public void onBeginRequest(Request request)

Called at the start of a request. It can be used for example to rebuild server state from the client request.

Parameters:

request - The request object

onEndRequest

public void onEndRequest(Request request)

Called at the end of a request. It can be used for instance to release temporary server state when using client state saving.

Parameters:

request - The request

createPageMap

public IPageMap createPageMap(java.lang.String name)

Parameters:

name -

Returns:

The pagemap instance

newVersionManager
