Create a Session store given a backend and configuration JSON.

Parameters:

vertx - vertx instance

Returns:

the store or runtime exception

create

static SessionStore create(Vertx vertx,
                           JsonObject options)

Create a Session store given a backend and configuration JSON.

Parameters:

vertx - vertx instance

options - extra options for initialization

Returns:

the store or runtime exception

init

SessionStore init(Vertx vertx,
                  JsonObject options)

Parameters:

vertx - the vertx instance

options - optional Json with extra configuration options

Returns:

self

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.

Returns:

the timeout value, in ms

createSession

Session createSession(long timeout)

Create a new session using the default min length.

Parameters:

timeout - - the session timeout, in ms

Returns:

the session

createSession

Session createSession(long timeout,
                      int length)

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

get

default Future<Session> get(String cookieValue)

Parameters:

cookieValue - the unique ID of the session

Returns:

future that will be called with a result holding the session, or a failure

See Also:

get(String, Handler)

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

delete

default Future<Void> delete(String cookieValue)

Parameters:

cookieValue - the unique ID of the session

Returns:

future that will be called with a result, or a failure

See Also:

delete(String, Handler)

put

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

Add a session with the specified ID.

Parameters:

session - the session

resultHandler - will be called with a success or a failure

put

default Future<Void> put(Session session)

Parameters:

session - the session

Returns:

future that will be called with a result, or a failure

See Also:

put(Session, Handler)

clear

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

Remove all sessions from the store.

Parameters:

resultHandler - will be called with a success or a failure

clear

Returns:

future that will be called with a result, or a failure

See Also:

clear(Handler)

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

size

default Future<Integer> size()

Returns:

future that will be called with a result, or a failure

See Also:

size(Handler)

close

void close()

Close the store
