## Class RequestValidator

- java.lang.Object
- - io.vertx.rxjava3.openapi.validation.RequestValidator

-     public class RequestValidator
      extends Object

  The `RequestValidator` requires the `parameters` in a specific format to be able to parse and validate them. This is especially true for exploded parameters. The following table shows how the value of a parameter of a request must be stored in a `ValidatableRequest` object. For these examples the key of those values is always color.

  These are the initial values for each type:
  - primitive (string) -> "blue"
  - array -> ["blue","black","brown"]
  - object -> { "R": 100, "G": 200, "B": 150 }
  For cookie parameters `ValidatedRequest.getCookies()`

       +--------+---------+-------+-----------+------------------------------------+-------------------------+
       | style  | explode | empty | primitive | array                              | object                  |
