    • Method Detail

      • expand

        public static JsonValue expand​(Map<String,​Object> object)
        Expands a Json Object Map, where the keys of the map are the JsonPointer s and the values are the value the JsonPointer resolves to. For Example, the following key-value pairs 
              /object/array/0 , "test"
      /object/array/1 , "test1"
      /string         , "stringVal"
      /boolean        , false
      /number         , 1
      /array/0        , "value1"
      /array/1        , "value2"
        will produce the following json object 
             {
         "object" : {
             "array" : ["test", "test1"]
         },
         "string" : "stringVal",
         "boolean" : false,
         "number" : 1,
         "array" : ["value1", "value2"]
     }
        Parameters:
        object - the Json Object Map containing the JsonPointer s and values
        Returns:
        the JsonValue expanded from the object map

      • flatten

        public static Map<String,​Object> flatten​(JsonValue jsonValue)
        Flattens a JsonValue to a Map, where the keys of the Map are JsonPointer s and the values are the value the JsonPointer s resolve to. For Example, the following JsonValue 
             {
         "object" : {
             "array" : ["test", "test1"]
         },
         "string" : "stringVal",
         "boolean" : false,
         "number" : 1,
         "array" : ["value1", "value2"]
     }
        will produce the following Map key-value pairs 
              /object/array/0 , "test"
      /object/array/1 , "test1"
      /string         , "stringVal"
      /boolean        , false
      /number         , 1
      /array/0        , "value1"
      /array/1        , "value2"
        Parameters:
        jsonValue - the JsonValue object to flatten
        Returns:
        a Map representing the flattened JsonValue object

      • extractValueAsString

        public static String extractValueAsString​(JsonValue json,
                                          String fieldName)
        Extracts String representation of field identified by fieldName from json object. JsonValue transformers are applied up to fieldName but not to its components.
        Parameters:
        json - the JsonValue object from which to extract a value.
        fieldName - the field identifier in a form consumable by JsonPointer.
        Returns:
        A non-null String representation of the field's value. If the specified field is not present or has a null value, null will be returned.

      • extractValueAsString

        public static String extractValueAsString​(JsonValue json,
                                          JsonPointer pointer)
        Extracts String representation of field identified by pointer from json object. JsonValue transformers are applied up to fieldName but not to its components.
        Parameters:
        json - the JsonValue object from which to extract a value.
        pointer - the field identifier as a JsonPointer.
        Returns:
        A non-null String representation of the field's value. If the specified field is not present or has a null value, null will be returned.
