ExpiringSessionRecycler class...

[Murat OZDEMiR]

Hello friends,
Would you pls. make my mind clear about ExpiringSessionRecycler class.
I wonder to learn what are the parameters of ExpiringSessionRecycler(int
timeToLive, int expirationInterval)? 
Is "timeToLive" second of milisecond?
Is "expirationInterval" a number which session will close after
"expirationInterval" times being idle?
 
I cannot find any description except "TODO Document me." :)
 
Best Regards...
