## Interface HTTPRequestValidationHandler

- All Superinterfaces:
    Handler<RoutingContext>, ValidationHandler

  Deprecated.
  You should use the new module vertx-web-openapi

      @Deprecated
      public interface HTTPRequestValidationHandler
      extends ValidationHandler

  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
