Method Details

• jsonEquals

  public static boolean jsonEquals(elemental.json.JsonValue a, elemental.json.JsonValue b)

  Compares two json values for deep equality.

  This is a helper for overcoming the fact that JsonValue doesn't override Object.equals(Object) and JsonValue.jsEquals(JsonValue) is defined to use JavaScript semantics where arrays and objects are equals only based on identity.

  Parameters:

  a - the first json value to check, may not be null

  b - the second json value to check, may not be null

  Returns:

  true if both json values are the same; false otherwise

• stringEqual

  public static boolean stringEqual(elemental.json.JsonValue a, elemental.json.JsonValue b)

• booleanEqual

  public static boolean booleanEqual(elemental.json.JsonValue a, elemental.json.JsonValue b)

• numbersEqual

  public static boolean numbersEqual(elemental.json.JsonValue a, elemental.json.JsonValue b)
