start
public void start()Ensures that thisStation
is up and running, starting up the selector thread if it has not yet been started.- Throws:
StationException
- if thisStation
has been stopped.
-
stop
public void stop()Ensures that thisStation
has been permanently stopped, shutting down the selector thread, if it's currently running. Upon return, thisStation
is guaranteed to be in the stopped state. -
transport
Binds the giventransport
to thisStation
, initializing thetransport
's context with the givenflowControl
state. TheStation
thereafter asynchronously executes I/O tasks on behalf of thetransport
when the underlying physical transport is ready for I/O operations permitted by thetransport
's current flow control state. Returns aTransportRef
, which can be used to modify the flow control of thetransport
, and to close thetransport
