Constructor Details

SimpleSession

public SimpleSession()
Default constructor - set lastTouched to now

Method Details

get

public Object get(String key)
Get a property from the session
Specified by:
get in interface Session
Parameters:
key - the name of the property desired.

getKeys

public Enumeration getKeys()
Get an enumeration of the keys in this session
Specified by:
getKeys in interface Session

getLastAccessTime

public long getLastAccessTime()

getLockObject

public Object getLockObject()
Get an Object suitable for synchronizing the session. This method exists because different session implementations might provide different ways of getting at shared data. For a simple hashtable- based session, this would just be the hashtable, but for sessions which use database connections, etc. it might be an object wrapping a table ID or somesuch.
Specified by:
getLockObject in interface Session

getTimeout

public int getTimeout()
Return the sessions' time-to-live.
Specified by:
getTimeout in interface Session
Returns:
the timeout value for this session.

invalidate

public void invalidate()
invalidate the session
Specified by:
invalidate in interface Session

remove

public void remove(String key)
Remove a property from the session
Specified by:
remove in interface Session
Parameters:
key - the name of the property desired.

set

public void set(String key,
                Object value)
Set a property in the session
Specified by:
set in interface Session
Parameters:
key - the name of the property to set.
value - the value of the property.

setTimeout

public void setTimeout(int timeout)
Set the session's time-to-live. This is implementation-specific, but basically should be the # of seconds of inactivity which will cause the session to time out and invalidate. "inactivity" is implementation-specific.
Specified by:
setTimeout in interface Session

touch

public void touch()
"Touch" the session (mark it recently used)
Specified by:
touch in interface Session
