restore

public void restore()

Description copied from interface: Persistence

Restore in the MW all the persisted information (registration, subscribers and callees)

Specified by:

restore in interface Persistence

storeUserPWD

public void storeUserPWD(String id,
                         String pwd)

Description copied from interface: Persistence

Store a new user-password pair for later authentication. There is no "change" method for this, so any change will require manual modification of the persistence.

Specified by:

storeUserPWD in interface Persistence

Parameters:

id - User

pwd - Password

checkUserPWD

public boolean checkUserPWD(String id,
                            String pwd)

Description copied from interface: Persistence

Method that checks the proper authentication of a persisted user-password pair.

Specified by:

checkUserPWD in interface Persistence

Parameters:

id - User

pwd - Password

Returns:

true if pwd matches the initially stored value and no errors occured

checkUser

public boolean checkUser(String id)

Description copied from interface: Persistence

Check if a user is already persisted with an associated password pair.

Specified by:

checkUser in interface Persistence

Parameters:

id - to check

Returns:

true if there is already a user-password pair persisted.

removeOlderThan

public void removeOlderThan(Long millis)

Maintenance method that removes all stored data from all tables that was introduced more than @param millis ago. Removal is not accurate to the millisecond, it rounds to the day.

Parameters:

millis - Minimum age, in milliseconds, at which the data will be removed (data older than this will be removed)
