HttpServerResponse (Vert.x Stack

java.lang.Object
- io.vertx.rxjava.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 Pump to pump data with flow control.
NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.

To avoid running out of memory by putting too much on the write queue, check the WriteStream.writeQueueFull() method before writing. This is done automatically if using a Pump.

```
public HttpServerResponse setWriteQueueMaxSize(int maxSize)
```
    Description copied from interface: WriteStream
    
    Set the maximum size of the write queue to maxSize. You will still be able to write to the stream even if there is more than maxSize items in the write queue. This is used as an indicator by classes such as Pump to provide flow control.
    The value is defined by the implementation of the stream, e.g in bytes for a NetSocket, the number of Message for a MessageProducer, etc...

  - drainHandler
```
public HttpServerResponse drainHandler(Handler<Void> handler)
```
    Description copied from interface: WriteStream
    
    Set a drain handler on the stream. If the write queue is full, then the handler will be called when the write queue is ready to accept buffers again. See Pump for an example of this being used.
    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

public int getStatusCode()
```
    Returns:
    
    the HTTP status code of the response. The default is 200 representing OK.
  - 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.
    
    Parameters:
    
    statusCode -
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - getStatusMessage
```
public String getStatusMessage()
```
    Returns:
    
    the HTTP status message of the response. If this is not specified a default value will be used depending on what setStatusCode(int) has been set to.

```
    Set the status message
    
    Parameters:

    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

    Parameters:
    
    name - the header name
    
    value - the header value.
    
    Returns:
    
    a reference to this, so the API can be used fluently

```
    Put an HTTP trailer
    
    Parameters:
    
    name - the trailer name
    
    value - the trailer value
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - closeHandler
```
public HttpServerResponse closeHandler(Handler<Void> handler)
```
    Set a close handler for the response, this is called when the underlying connection is closed and the response was still using the connection.
    For HTTP/1.x it is called when the connection is closed before end() is called, therefore it is not guaranteed to be called.
    For HTTP/2 it is called when the related stream is closed, and therefore it will be always be called.

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

    Parameters:
    
    method -
    
    path -
    
    Returns:
  - push
```
public HttpServerResponse push(HttpMethod method,
                               String host,
                               String path,

                               Handler<AsyncResult<HttpServerResponse>> handler)
```
    Push a response to the client.
    The handler will be notified with a success when the push can be sent and with a failure when the client has disabled push or reset the push before it has been sent.
    The handler may be queued if the client has reduced the maximum number of streams the server can push concurrently.
    Push can be sent only for peer initiated streams and if the response is not ended.
    
    Parameters:
    
    method - the method of the promised request
    
    host - the host of the promised request
    
    path - the path of the promised request
    
    headers - the headers of the promised request
    
    handler - the handler notified when the response can be written
    
    Returns:
    
    a reference to this, so the API can be used fluently
  - pushObservable
