retryTimeout

long retryTimeout()

The retry timeout value in milli seconds used by the session handler when it retrieves a value from the store.

A non positive value means there is no retry at all.

Create a new session.

Parameters:

timeout - - the session timeout, in ms

length - - the required length for the session id

Returns:

the session

get

void get(String cookieValue,
         Handler<AsyncResult<Session>> resultHandler)

Get the session with the specified ID.

Parameters:

cookieValue - the unique ID of the session

resultHandler - will be called with a result holding the session, or a failure

delete

void delete(String id,
            Handler<AsyncResult<Void>> resultHandler)

Delete the session with the specified ID.

Parameters:

id - the session id

resultHandler - will be called with a success or a failure

put

void put(Session session,
         Handler<AsyncResult<Void>> resultHandler)

Add a session with the specified ID.

clear

void clear(Handler<AsyncResult<Void>> resultHandler)

Remove all sessions from the store.

Parameters:

resultHandler - will be called with a success or a failure

size

void size(Handler<AsyncResult<Integer>> resultHandler)

Get the number of sessions in the store.

Beware of the result which is just an estimate, in particular with distributed session stores.

Parameters:

resultHandler - will be called with the number, or a failure

close

void close()

Close the store
