    Returns:
    
    The host part of the destination address
  - getHostAndPort
```
public String getHostAndPort()

  - dispatch
```
public HttpServerExchange dispatch(Runnable runnable)

    Parameters:
    
    runnable - The task to run
    
    Throws:
    
    IllegalStateException - If this exchange has already been dispatched

    the channel for the inbound request, or null if another party already acquired the channel
  - isRequestChannelAvailable
```
public boolean isRequestChannelAvailable()
```
  - isComplete
```
public boolean isComplete()
```
    Returns true if the completion handler for this exchange has been invoked, and the request is considered finished.
  - isRequestComplete
```
public boolean isRequestComplete()
```
    Returns true if all data has been read from the request, or if there was not data.
    
    Returns:
    
    true if the request is complete
  - isResponseComplete
```
public boolean isResponseComplete()
```
    Returns:
    
    true if the responses is complete
  - getResponseChannel
```
public org.xnio.channels.StreamSinkChannel getResponseChannel()
```
    Get the response channel. The channel must be closed and fully flushed before the next response can be started. In order to close the channel you must first call SuspendableWriteChannel.shutdownWrites(), and then call SuspendableWriteChannel.flush() until it returns true. Alternatively you can call endExchange(), which will close the channel as part of its cleanup.
    Closing a fixed-length response before the corresponding number of bytes has been written will cause the connection to be reset and subsequent requests to fail; thus it is important to ensure that the proper content length is delivered when one is specified. The response channel may not be writable until after the response headers have been sent.
    If this method is not called then an empty or default response body will be used, depending on the response code set.
    The returned channel will begin to write out headers when the first write request is initiated, or when SuspendableWriteChannel.shutdownWrites() is called on the channel with no content being written. Once the channel is acquired, however, the response code and headers may not be modified.
    
    Returns:
    
    the response channel, or null if another party already acquired the channel
  - getResponseSender
```
public Sender getResponseSender()
```
    Get the response sender.
    For blocking exchanges this will return a sender that uses the underlying output stream.
    
    Returns:
    
    the response sender, or null if another party already acquired the channel or the sender

  - setResponseCode
```
@Deprecated
public HttpServerExchange setResponseCode(int statusCode)
```
    Deprecated.
    
    Change the status code for this response. If not specified, the code will be a 200. Setting the status code after the response headers have been transmitted has no effect.
    
    Parameters:
    
    statusCode - the new code
    
    Throws:
    
    IllegalStateException - if a response or upgrade was already sent
    
    See Also:
    
    setStatusCode(int)
  - getStatusCode
```
public int getStatusCode()
```
    Get the status code.
    
    Returns:
    
    the status code
  - setStatusCode
```
public HttpServerExchange setStatusCode(int statusCode)
```
    Change the status code for this response. If not specified, the code will be a 200. Setting the status code after the response headers have been transmitted has no effect.
    
    Parameters:
    
    statusCode - the new code
    
    Throws:
    
    IllegalStateException - if a response or upgrade was already sent
  - setReasonPhrase
```
public HttpServerExchange setReasonPhrase(String message)
```
    Sets the HTTP reason phrase. Depending on the protocol this may or may not be honoured. In particular HTTP2 has removed support for the reason phrase. This method should only be used to interact with legacy frameworks that give special meaning to the reason phrase.
    
    Parameters:
    
    message - The status message
    
    Returns:
    
    this exchange
  - getReasonPhrase
```
public String getReasonPhrase()
```
    Returns:
    
    The current reason phrase
  - addRequestWrapper
```
public HttpServerExchange addRequestWrapper(ConduitWrapper<org.xnio.conduits.StreamSourceConduit> wrapper)
```
    Adds a ConduitWrapper to the request wrapper chain.
    
    Parameters:
    
    wrapper - the wrapper
  - addResponseWrapper
```
public HttpServerExchange addResponseWrapper(ConduitWrapper<org.xnio.conduits.StreamSinkConduit> wrapper)
```
    Adds a ConduitWrapper to the response wrapper chain.
    
    Parameters:
    
    wrapper - the wrapper
  - startBlocking
```
public BlockingHttpExchange startBlocking()
```
    Calling this method puts the exchange in blocking mode, and creates a BlockingHttpExchange object to store the streams.
    When an exchange is in blocking mode the input stream methods become available, other than that there is presently no major difference between blocking an non-blocking modes.
    
    Returns:
    
    The existing blocking exchange, if any
  - startBlocking
```
public BlockingHttpExchange startBlocking(BlockingHttpExchange httpExchange)
```
    Calling this method puts the exchange in blocking mode, using the given blocking exchange as the source of the streams.
    When an exchange is in blocking mode the input stream methods become available, other than that there is presently no major difference between blocking an non-blocking modes.
    Note that this method may be called multiple times with different exchange objects, to allow handlers to modify the streams that are being used.
    
    Returns:
    
    The existing blocking exchange, if any
  - isBlocking
```
public boolean isBlocking()
```
    Returns true if startBlocking() or startBlocking(BlockingHttpExchange) has been called.
    
    Returns:
    
    true If this is a blocking HTTP server exchange
  - getInputStream
```
public InputStream getInputStream()
```
    Returns:
    
    The input stream
    
    Throws:
    
    IllegalStateException - if startBlocking() has not been called
  - getOutputStream
```
public OutputStream getOutputStream()
```
    Returns:
    
    The output stream
    
    Throws:
    
    IllegalStateException - if startBlocking() has not been called
  - getRequestStartTime
```
public long getRequestStartTime()
```
    Returns:
    
    The request start time using the JVM's high-resolution time source, in nanoseconds, or -1 if this was not recorded
    
    See Also:
    
    UndertowOptions.RECORD_REQUEST_START_TIME, Connectors.setRequestStartTime(HttpServerExchange)
  - endExchange
```
public HttpServerExchange endExchange()
```
    Ends the exchange by fully draining the request channel, and flushing the response channel.
    This can result in handoff to an XNIO worker, so after this method is called the exchange should not be modified by the caller.
    If the exchange is already complete this method is a noop
  - getIoThread
```
public org.xnio.XnioIoThread getIoThread()
```
  - getMaxEntitySize
```
public long getMaxEntitySize()
```
    Returns:
    
    The maximum entity size for this exchange
  - setMaxEntitySize
```
public HttpServerExchange setMaxEntitySize(long maxEntitySize)
```
    Sets the max entity size for this exchange. This cannot be modified after the request channel has been obtained.
    
    Parameters:
    
    maxEntitySize - The max entity size
  - getSecurityContext
```
public SecurityContext getSecurityContext()
```
  - setSecurityContext
```
public void setSecurityContext(SecurityContext securityContext)
```
  - addResponseCommitListener
```
public void addResponseCommitListener(ResponseCommitListener listener)
```
    Adds a listener that will be invoked on response commit
    
    Parameters:
    
    listener - The response listener
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
