Constructor Detail

SynchronizationAdapter

public SynchronizationAdapter()

Method Detail

onComplete

public void onComplete(Exchange exchange)

Description copied from interface: Synchronization

Called when the processing of the message exchange is complete

Specified by:

onComplete in interface Synchronization

Parameters:

exchange - the exchange being processed

onFailure

public void onFailure(Exchange exchange)

Description copied from interface: Synchronization

Called when the processing of the message exchange has failed for some reason. The exception which caused the problem is in Exchange.getException() and there could be a fault message via Message.isFault()

Specified by:

onFailure in interface Synchronization

Parameters:

exchange - the exchange being processed

onDone

public void onDone(Exchange exchange)

allowHandover

public boolean allowHandover()

Description copied from interface: SynchronizationVetoable

Whether or not handover this synchronization is allowed.

For example when an Exchange is being routed from one thread to another thread, such as using request/reply over SEDA

Specified by:

allowHandover in interface SynchronizationVetoable

Returns:

true to allow handover, false to deny.

getOrder

public int getOrder()

Description copied from interface: Ordered

Gets the order.

Use low numbers for higher priority. Normally the sorting will start from 0 and move upwards. So if you want to be last then use Integer.MAX_VALUE or eg Ordered.LOWEST.

Specified by:

getOrder in interface Ordered

Returns:

the order

onBeforeRoute

public void onBeforeRoute(Route route,
                          Exchange exchange)

Description copied from interface: SynchronizationRouteAware

Invoked before the Exchange is being routed by the given route.

Notice if the exchange is being routed through multiple routes, there will be callbacks for each route.

Important: this callback may not invoked if the SynchronizationRouteAware implementation is being added to the UnitOfWork after the routing has started.

Specified by:

onBeforeRoute in interface SynchronizationRouteAware

Parameters:

route - the route

exchange - the exchange

onAfterRoute

public void onAfterRoute(Route route,
                         Exchange exchange)

Description copied from interface: SynchronizationRouteAware

Invoked after the Exchange has been routed by the given route.

Notice if the exchange is being routed through multiple routes, there will be callbacks for each route.

This invocation happens before these callbacks:

• The consumer of the route writes any response back to the caller (if in InOut mode)
• The UoW is done calling either Synchronization.onComplete(org.apache.camel.Exchange) or Synchronization.onFailure(org.apache.camel.Exchange)

This allows custom logic to be executed after all routing is done, but before the Consumer prepares and writes any data back to the caller (if in InOut mode).

Specified by:

onAfterRoute in interface SynchronizationRouteAware

Parameters:

route - the route

exchange - the exchange
