  • Method Details

    • intercept

      default ReactiveExchangeHandler<A,B> intercept(ExchangeInterceptor<A,B> interceptor)

      Returns a composed exchange handler that first applies the interceptor to transform the exchange and then invoke the defer(io.inverno.mod.http.server.Exchange).

      Parameters:
      interceptor - the interceptor
      Returns:
      a composed exchange handler

    • defer

      Mono<Void> defer(B exchange) throws HttpException

      Returns a Mono that defers the processing of the exchange.

      This method is invoked by the HTTP server which then subscribes to the resulting Mono and, on completion, to the exchange response body data publisher to respond to the client.

      Parameters:
      exchange - the exchange to process
      Returns:
      an empty mono that completes when the exchange has been processed
      Throws:
      HttpException - if an error occurs during the processing of the exchange
