All Implemented Interfaces:

AdaptrisComponent, ComponentLifecycle, ComponentLifecycleExtension, MessageEventGenerator, Service, StateManagedComponent

@ComponentProfile(summary="Runs the configured service/list for each multi-payload message payload.",
                  tag="for,each,for each,for-each,then,multi-payload",
                  since="3.10.0")
public class ForEach
extends ServiceImp

A for-each implementation that iterates over the payloads in a multi-payload message MultiPayloadAdaptrisMessage. For each payload then execute the given service (list). The default is to use a single thread to iterate over the payloads, but a thread pool can be used to parallelize the loop.

 
 <for-each-payload>
   <unique-id>for-each-id</unique-id>
   <then>
     <service class="shared-service">
       <lookup-name>for-each-service-list-id</lookup-name>
       <unique-id>for-each-service-list-id</unique-id>
     </service>
   </then>
   <thread-count>1</thread-count>
 </for-each-payload>
 
 

Note: If your service list for each payload contains a StopProcessingService it will not stop the processing of each payload.

Since:

3.10

In the adapter configuration file this class is aliased as for-each-payload which is the preferred alternative to the fully qualified classname when building your configuration.

Constructor Detail

ForEach

public ForEach()

Method Detail

getThen

public ThenService getThen()

Get the for-each-then service.

Returns:

The service.

setThen

public void setThen(ThenService thenService)

Set the for-each-then service.

Parameters:

thenService - The service.

getThreadCount

public java.lang.Integer getThreadCount()

Get the number of threads to use.

Returns:

The number of threads.

setThreadCount

public void setThreadCount(java.lang.Integer threadCount)

Set the number of threads to use. If set to 0 then as many threads as there are payloads will be used.

Parameters:

threadCount - The number of threads.

doService

public void doService(AdaptrisMessage msg)
               throws ServiceException

Apply the service to the message.

.

Parameters:

msg - the AdaptrisMessage to process

Throws:

ServiceException - wrapping any underlying Exceptions

initService

protected void initService()
                    throws CoreException

Specified by:

initService in class ServiceImp

Throws:

CoreException

closeService

protected void closeService()

Specified by:

closeService in class ServiceImp

prepare

public void prepare()
             throws CoreException

Prepare for initialisation.

Throws:

CoreException

start

public void start()
           throws CoreException

Starts the component.

Once a component is started it should be ready to process messages. In the case of AdaptrisMessageConsumer, calling start will begin message delivery.

Specified by:

start in interface ComponentLifecycle

Overrides:

start in class ServiceImp

Throws:

CoreException - wrapping any underlying Exceptions

stop

public void stop()

Stop the component

A stopped component is not expected to be ready to process messages. In the case of AdaptrisMessageConsumer, calling stop will pause message delivery. Throwing a RuntimeException may cause unintended consequences

Specified by:

stop in interface ComponentLifecycle

Overrides:

stop in class ServiceImp
