      • resolvePath

        public static String resolvePath​(Feature feature,
                                 String jsonPath)
        Concat the parent path if it exists to the provided JSON path.

      • setParentPath

        public static void setParentPath​(Feature feature,
                                 String parentPath)
        Store the parent path in a feature user data map.

      • getValue

        public static Object getValue​(Object object,
                              String jsonPath)
        Will try to extract from the provided object the value that correspond to the given json path.

      • extractFeature

        public static Feature extractFeature​(Object feature,
                                     String jsonPath)

      • extractFeature

        public static Feature extractFeature​(Feature feature,
                                     String jsonPath)
        Method for extracting or casting a feature from the provided object.

      • getValue

        public static Object getValue​(DBObject mongoObject,
                              String jsonPath,
                              Supplier<GeometryCoordinateSequenceTransformer> transformer)
        Will extract from the mongo db object the value that correspond to the given json path. If the path contain a nested list of values an exception will be throw.

      • getValue

        public static Object getValue​(DBObject mongoObject,
                              Map<String,​Integer> collectionsIndexes,
                              String jsonPath,
