## Class HttpServerResponse

- java.lang.Object
- - io.vertx.reactivex.core.http.HttpServerResponse

- All Implemented Interfaces:
    StreamBase, WriteStream<Buffer>

      public class HttpServerResponse
      extends Object
      implements WriteStream<Buffer>

  Represents a server-side HTTP response.

  An instance of this is created and associated to every instance of `HttpServerRequest` that.

  It allows the developer to control the HTTP response that is sent back to the client for a particular HTTP request.

  It contains methods that allow HTTP headers and trailers to be set, and for a body to be written out to the response.

  It also allows files to be streamed by the kernel directly from disk to the outgoing HTTP connection, bypassing user space altogether (where supported by the underlying operating system). This is a very efficient way of serving files from the server since buffers do not have to be read one by one from the file and written to the outgoing socket.

  It implements `WriteStream` so it can be used with `Pipe` to pipe data with flow control.

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

      The stream implementation defines when the drain handler, for example it could be when the queue size has been reduced to `maxSize / 2`.

      Specified by:
        `drainHandler` in interface `WriteStream<Buffer>`
      Parameters:
        `handler` - the handler
      Returns:

    - #### getStatusCode

          public int getStatusCode()

    - #### setStatusCode

          public HttpServerResponse setStatusCode(int statusCode)

      Set the status code. If the status message hasn't been explicitly set, a default status message corresponding to the code will be looked-up and used.

        `statusCode` -
      Returns:
        a reference to this, so the API can be used fluently

    - #### getStatusMessage

          public String getStatusMessage()

    - #### setStatusMessage

          public HttpServerResponse setStatusMessage(String statusMessage)

      Set the status message
      Parameters:
        `statusMessage` -
      Returns:
        a reference to this, so the API can be used fluently

    - #### setChunked

          public HttpServerResponse setChunked(boolean chunked)

      If `chunked` is `true`, this response will use HTTP chunked encoding, and each call to write to the body will correspond to a new HTTP chunk sent on the wire.

      If chunked encoding is used the HTTP header `Transfer-Encoding` with a value of `Chunked` will be automatically inserted in the response.

      If `chunked` is `false`, this response will not use HTTP chunked encoding, and therefore the total size of any data that is written in the respone body must be set in the `Content-Length` header before any data is written out.

      An HTTP chunked response is typically used when you do not know the total size of the request body up front.

      Parameters:
        `chunked` -
      Returns:
        a reference to this, so the API can be used fluently

    - #### isChunked

          public boolean isChunked()

      Returns:
        is the response chunked?

    - #### headers
