Package io.vertx.ext.web.openapi.router

## Interface RouterBuilder

-     public interface RouterBuilder

  Interface to build a Vert.x Web `Router` from an OpenAPI 3 contract.

  The router is mounting its handlers in the following order:
  1. RootHandler
  in the order the root handlers were added to the RouterBuilder.
  2. ValidationHandler
  This handler is implementing the marker interface `InputTrustHandler`. Because of this, all handlers of type PLATFORM, SECURITY_POLICY, BODY and AUTHENTICATION must be mounted as root handlers if required.
  3. UserHandler
  The custom user handlers defined in the `OpenAPIRoute` in the same order as they are added to the route.
  4. FailureHandler
  The failure handlers defined in the `OpenAPIRoute` in the same order as they are added to the route.

  - ### Method Detail

    - #### create

          static RouterBuilder create​(Vertx vertx,
                                      OpenAPIContract contract)

      Create a new `RouterBuilder`. Like `create(Vertx, OpenAPIContract, RequestExtractor)` but uses a default implementation for the extractor.
      Parameters:
        `vertx` - the related Vert.x instance
        `contract` - the contract that describes the endpoint
      Returns:
        an instance of `RouterBuilder`

    - #### create

          static RouterBuilder create​(Vertx vertx,
                                      OpenAPIContract contract,
                                      RequestExtractor extractor)

      Create a new `RouterBuilder`.
      Parameters:
        `vertx` - the related Vert.x instance
        `contract` - the contract that describes the endpoint
        `extractor` - the extractor is used to extract and transform the parameters and body of the related request in a format that can be validated by the `RequestValidator`.
      Returns:
        an instance of `RouterBuilder`

    - #### getRoute

          OpenAPIRoute getRoute​(String operationId)

      Access to a route defined in the contract with `operationId`
      Parameters:
        `operationId` - the id of the operation
      Returns:
        the requested route, or null if the passed operationId doesn't exist.

    - #### getRoutes

          List<OpenAPIRoute> getRoutes()

      Returns:
        all routes defined in the contract

    - #### rootHandler

          RouterBuilder rootHandler​(Handler<RoutingContext> rootHandler)

      Add global handler to be applied prior to `Router` being generated.
      Parameters:
        `rootHandler` - the root handler to add
      Returns:
        self

    - #### security

          Security security​(String securitySchemeName)

      Creates a new security scheme for the required `AuthenticationHandler`.
      Returns:
        a security scheme.

    - #### createRouter

          Router createRouter()

      Construct a new router based on the related OpenAPI contract.
      Returns:
        a Router based on the related OpenAPI contract.
