A handle which represents connection between two endpoints regardless of transport types.
Session provides user-defined attributes. User-defined attributes are application-specific data which is associated with a session. It often contains objects that represents the state of a higher-level protocol and becomes a way to exchange data between filters and handlers.

public int getIdleCount(IdleStatus status)
IdleStatus
.
If sessionIdle event is fired first after some time after I/O, idleCount becomes 1. idleCount resets to 0 if any I/O occurs again, otherwise it increases to 2 and so on if sessionIdle event is fired again without any I/O between two (or more) sessionIdle events.
public long getLastIdleTime(IdleStatus status)
IdleStatus
.
