How to clear the cache of MemoryIdempotentRepository

[Reto Peter]

Hi all

I have a route, which checks for uniqueness of a certain value (find 
duplicates, and in case of duplicates, the route will throw an exception).
That works fine so far.

At the end of the route, I want to clear the cache, so next time the route gets 
executed, it shall start with an empty cache.

My question: How can I clear the cache at the end of the route?

My route(simplified)


from("direct:processArticles")

      .split(xpath("//Article")) // for each Article

             .setHeader("ArtEAN", xpath("Article/ArtEAN/text()"))

             .idempotentConsumer(header("ArtEAN"), 
MemoryIdempotentRepository.memoryIdempotentRepository(2000)).skipDuplicate(false)

      
.choice().when(header(Exchange.DUPLICATE_MESSAGE).isEqualTo(true)).throwException(ImportException.class,
 "Line/Unit: ${exchangeProperty.CamelSplitIndex}: Found Duplicates").end()

             // do some processing

      .end()
