Defining a Custom Single Duplicate Check Key Mapping
This page explains how to define a mapping for a single duplicate check e.g. a message level duplicate check.
1. Add a mapping function
Within your MPS project, add a Mapping Library to your model. Right-click on your model and choose new → v2Flo → Mapping Library.
Add your function to this library and complete its details. The input data represents the message type you wish to duplicate check. The output data must be Duplicate Check Key.
2. Use the mapping function within your flow
Within your MPS flow, left-click on the checkSingleDuplicate action call you want to use the custom mapping with.
Press Ctrl+Alt+I to open the Inspector. Change the Mapping in the inspector to your mapping function.
3. Implement your mapping adapter
You need to provide a java implementation of your mapping function and provide it into your domain declaration as an adapter.
For example:
public class CustomDuplicateCheckMappingAdapter implements CustomDuplicateCheckMappingMappingPort {
@Override
public CustomSingleDuplicateMapFromPain001MappingOutput performCustomSingleDuplicateMapFromPain001(CustomSingleDuplicateMapFromPain001MappingParameters inputParameters) {
return new CustomSingleDuplicateMapFromPain001MappingOutput(DuplicateCheckKey.builder().data(getDuplicateCheckFields(inputParameters.getPaymentInitiation()).build()));
}
private List<String> getDuplicateCheckFields(CustomerCreditTransferInitiationV09 pain001) {
List<String> data = new ArrayList<>();
// your code here to populate data with the fields you want
return data;
}
} @Bean
public DuplicatecheckexampleDomain duplicatecheckexampleDomain(ActorSystem actorSystem,
CustomDuplicateCheckMappingMappingPort customDuplicateCheckMappingAdapter,
Dispatcher floDispatcher) {
return new DuplicatecheckexampleDomain.Builder(actorSystem)
.withCustomDuplicateCheckMappingMappingAdapter(customDuplicateCheckMappingAdapter)
.withDispatcher(floDispatcher)
.build();
