Method Detail

onExchangeBegin

public void onExchangeBegin(Route route,
                            Exchange exchange)

Description copied from interface: RoutePolicy

Callback invokes when an Exchange is started being routed on the given Route

Specified by:

onExchangeBegin in interface RoutePolicy

Parameters:

route - the route where the exchange started from

exchange - the created exchange

onExchangeDone

public void onExchangeDone(Route route,
                           Exchange exchange)

Description copied from interface: RoutePolicy

Callback invokes when an Exchange is done being routed, where it started from the given Route

Notice this callback is invoked when the Exchange is done and the Route is the route where the Exchange was started. Most often its also the route where the exchange is done. However its possible to route an Exchange to other routes using endpoints such as direct or seda. Bottom line is that the Route parameter may not be the endpoint route and thus why we state its the starting route.

Specified by:

onExchangeDone in interface RoutePolicy

Parameters:

route - the route where the exchange started from

exchange - the created exchange
