#

from SessionStore import SessionStore

#

A simple volatile (non-persistent) session store for session3.

class VolatileSessionStore(SessionStore):
    is_multiprocess_safe = True
    is_thread_safe = True

#

Create the dictionary.

    def __init__(self):
        self.sessions = {}

#

Return the session if it exists, else return ‘default’.

    def load_session(self, id, default=None):
        return self.sessions.get(id, default)

#

Save the session in the dictionary..

    def save_session(self, session):
        self.sessions[session.id] = session

#

Delete the session in the dictionary.

    def delete_session(self, session):
        if session.id in self.sessions:
            del self.sessions[session.id]

#

Return true if the session exists in the dictionary, else false.

    def has_session(self, id):
        return id in self.sessions
