Method Detail

init

void init(Context context)

Has to be called initially. => maybe in the future as assisted inject.

Parameters:

context - The context of this session.

getId

String getId()

Returns:

id of a session.

getData

Map<String,String> getData()

Returns:

complete content of session as immutable copy.

getAuthenticityToken

String getAuthenticityToken()

Returns:

a authenticity token (may generate a new one if the session currently does not contain the token).

save

void save(Context context)

To finally send this session to the user this method has to be called. It basically serializes the session into the header of the response.

Parameters:

context - The context from where to deduct a potentially existing session.

put

void put(String key,
         String value)

Puts key / value into the session. PLEASE NOTICE: If value == null the key will be removed!

Parameters:

key - Name of the key to store in the session.

value - The value to store in the session

get

String get(String key)

Returns the value of the key or null.

Parameters:

key - Name of the key to retrieve.

Returns:

The value of the key or null.

remove

String remove(String key)

Removes the value of the key and returns the value or null.

Parameters:

key - name of the key to remove

Returns:

original value of the key we just removed

clear

void clear()

Removes all values from the session.

isEmpty

boolean isEmpty()

Returns true if the session is empty, e.g. does not contain anything else than the timestamp key.

Returns:

true if session does not contain any values / false if it contains values.

setExpiryTime

void setExpiryTime(Long expiryTimeMs)

Use an alternative expiry time, this can be used to implement a longer expiry time for 'remember me' style functionality. The expiry time is persisted in the session.

Parameters:

expiryTimeMs - the expiry time in milliseconds, set to null to remove the expiry time from the session and use the application default.
