All Implemented Interfaces:

CamelContextAware, AggregationStrategy, Service, ShutdownableService, StatefulService, SuspendableService

public final class AggregationStrategyBeanAdapter
extends ServiceSupport
implements AggregationStrategy, CamelContextAware

An AggregationStrategy that adapts to a POJO.

public CamelContext getCamelContext()

Description copied from interface: CamelContextAware

Get the CamelContext

Specified by:

getCamelContext in interface CamelContextAware

Returns:

camelContext the Camel context

setCamelContext

public void setCamelContext(CamelContext camelContext)

Description copied from interface: CamelContextAware

Injects the CamelContext

Specified by:

setCamelContext in interface CamelContextAware

Parameters:

camelContext - the Camel context

getMethodName

public String getMethodName()

setMethodName

public void setMethodName(String methodName)

public boolean isAllowNullOldExchange()

setAllowNullOldExchange

public void setAllowNullOldExchange(boolean allowNullOldExchange)

isAllowNullNewExchange

public boolean isAllowNullNewExchange()

setAllowNullNewExchange

public void setAllowNullNewExchange(boolean allowNullNewExchange)

aggregate

public Exchange aggregate(Exchange oldExchange,
                 Exchange newExchange)

Description copied from interface: AggregationStrategy

Aggregates an old and new exchange together to create a single combined exchange

Specified by:

aggregate in interface AggregationStrategy

Parameters:

oldExchange - the oldest exchange (is null on first aggregation as we only have the new exchange)

newExchange - the newest exchange (can be null if there was no data possible to acquire)

Returns:

a combined composite of the two exchanges

isValidMethod

protected boolean isValidMethod(Method method)

Validates whether the given method is valid.

Parameters:

method - the method

Returns:

true if valid, false to skip the method

doStart

protected void doStart()
                throws Exception

Description copied from class: ServiceSupport

Implementations override this method to support customized start/stop.

Important: See ServiceSupport.doStop() for more details.

Specified by:

doStart in class ServiceSupport

Throws:

Exception

See Also:

ServiceSupport.doStop()

doStop

protected void doStop()
               throws Exception

Description copied from class: ServiceSupport

Implementations override this method to support customized start/stop.

Important: Camel will invoke this ServiceSupport.doStop() method when the service is being stopped. This method will also be invoked if the service is still in uninitialized state (eg has not been started). The method is always called to allow the service to do custom logic when the service is being stopped, such as when CamelContext is shutting down.

Specified by:

doStop in class ServiceSupport

Throws:

Exception

See Also:

ServiceSupport.doStart()
