## Class HTTPRequestValidationHandler

- java.lang.Object
- - io.vertx.reactivex.ext.web.api.validation.HTTPRequestValidationHandler

- All Implemented Interfaces:
    Handler<RoutingContext>, ValidationHandler

      public class HTTPRequestValidationHandler
      extends Object
      implements ValidationHandler, Handler<RoutingContext>

  An interface for add HTTP Request validation. This class can validate parameters inside query, path, headers an body (watch below)
  You can assign multiple body type at the same time(for example a JSON schema together with a XML schema). This interface support:
  - application/x-www-form-urlencoded
  - multipart/form-data
  - application/xml
  - application/json
  Also you can add a form parameter for validation without care about content type of your request. For form parameters this interface support both "multipart/form-data" and "application/x-www-form-urlencoded"
  This interface allow extra parameters in the request, so it doesn't care if in a request there's a parameter without a specified validation rule
  If a parameter is flagged as an array, it will be validated also if the size of array is 1 element

  NOTE: This class has been automatically generated from the `original` non RX-ified interface using Vert.x codegen.
