Hello, I have a json file containing the elasticsearch mapping for a type - let's call it "mapping.json". Currently we use Map\ mapping = mapper.readValue(mappingFileContent, HashMap.class) and then mapping.get("properties") to get the list of properties etc. We prefer if there was something like ElasticMapping.class so that we can say ElasticMapping elasticMapping = mapper.readValue(mappingFileContent, ElasticMapping.class) . And then elasticMapping.getProperties().get(0).getType() .... I see there is MappingMetadata.class but it doesn't look that it is created with this purpose? ---

There isn't a static view of the mapping at the level (classes that map one to one, fields wise, to how the mappings are defined), its not needed in elasticsearch.

We will probably create one for our custom needs. Ok, thanks for the fast answer.
