Method Summary

Session	getSession(SessionKey key) Retrieves the session corresponding to the specified contextual data (such as a session ID if applicable), or null if no Session could be found.
Session	start(SessionContext context) Starts a new session based on the specified contextual initialization data, which can be used by the underlying implementation to determine how exactly to create the internal Session instance.

Method Detail

start

Session start(SessionContext context)

Starts a new session based on the specified contextual initialization data, which can be used by the underlying implementation to determine how exactly to create the internal Session instance.

This method is mainly used in framework development, as the implementation will often relay the argument to an underlying SessionFactory which could use the context to construct the internal Session instance in a specific manner. This allows pluggable Session creation logic by simply injecting a SessionFactory into the SessionManager instance.

Parameters:

context - the contextual initialization data that can be used by the implementation or underlying SessionFactory when instantiating the internal Session instance.

Returns:

the newly created session.

getSession

Session getSession(SessionKey key)
                   throws SessionException

Retrieves the session corresponding to the specified contextual data (such as a session ID if applicable), or null if no Session could be found. If a session is found but invalid (stopped or expired), a SessionException will be thrown.

Parameters:

key - the Session key to use to look-up the Session

Returns:

the Session instance corresponding to the given lookup key or null if no session could be acquired.

Throws:

SessionException - if a session was found but it was invalid (stopped/expired).
