Examples with MapType com.fasterxml.jackson.databind.type.MapType used on opensource projects

Example 1 with MapType

use of com.fasterxml.jackson.databind.type.MapType in project hadoop by apache.

the class TestWebHDFS method toBlockLocationArray.

private BlockLocation[] toBlockLocationArray(String json) throws IOException {
    ObjectMapper mapper = new ObjectMapper();
    MapType subType = mapper.getTypeFactory().constructMapType(Map.class, String.class, BlockLocation[].class);
    MapType rootType = mapper.getTypeFactory().constructMapType(Map.class, mapper.constructType(String.class), mapper.constructType(subType));
    Map<String, Map<String, BlockLocation[]>> jsonMap = mapper.readValue(json, rootType);
    Map<String, BlockLocation[]> locationMap = jsonMap.get("BlockLocations");
    BlockLocation[] locationArray = locationMap.get(BlockLocation.class.getSimpleName());
    return locationArray;
}

    TypeFactory tf = TypeFactory.defaultInstance();
    JavaType t = tf.constructType(new TypeReference<LongValuedMap<String>>() {
    });
    MapType type = (MapType) t;
