clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait

	Object	clone()
		Answers a new instance of the same class as the receiver, whose slots have been filled in with the values in the slots of the receiver.
	boolean	equals(Object o)
		Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison.
	void	finalize()
		Called by the virtual machine when there are no longer any (non-weak) references to the receiver.
final	Class	getClass()
		Answers the unique instance of java.lang.Class which represents the class of the receiver.
	int	hashCode()
		Answers an integer hash code for the receiver.
final	void	notify()
		Causes one thread which is `wait` ing on the receiver to be made ready to run.
final	void	notifyAll()
		Causes all threads which are `wait` ing on the receiver to be made ready to run.
	String	toString()
		Answers a string containing a concise, human-readable description of the receiver.
final	void	wait(long time, int frac)
		Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by `notify` or `notifyAll`) or the expiration of the timeout.
final	void	wait(long time)
		Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by `notify` or `notifyAll`) or the expiration of the timeout.
final	void	wait()
		Causes the thread which sent this message to be made not ready to run pending some change in the receiver (as indicated by `notify` or `notifyAll`).

Public Methods

public void flush()

Writes out all pending buffered data over the open connection.

Throws

IOException

public HttpConnectionMetrics getMetrics()

Returns a collection of connection metrcis

public boolean isResponseAvailable(int timeout)

Checks if response data is available from the connection. May wait for the specified time until some data becomes available. Note that some implementations may completely ignore the timeout parameter.

Throws

IOException

public boolean isStale()

Checks whether this connection has gone down. Network connections may get closed during some time of inactivity for several reasons. The next time a read is attempted on such a connection it will throw an IOException. This method tries to alleviate this inconvenience by trying to find out if a connection is still usable. Implementations may do that by attempting a read with a very small timeout. Thus this method may block for a small amount of time before returning a result. It is therefore an expensive operation.

public void receiveResponseEntity(HttpResponse response)

Receives the next response entity available from this connection and attaches it to an existing HttpResponse object.

Throws

HttpException
IOException

public HttpResponse receiveResponseHeader()

Receives the request line and headers of the next response available from this connection. The caller should examine the HttpResponse object to find out if it should try to receive a response entity as well.

Throws

HttpException
IOException

public void sendRequestEntity(HttpEntityEnclosingRequest request)

Sends the request entity over the connection.

Throws

HttpException
IOException

public void sendRequestHeader(HttpRequest request)

Sends the request line and all headers over the connection.

Throws

HttpException
IOException

				void	close()
					Closes this connection gracefully.
				HttpConnectionMetrics	getMetrics()
					Returns a collection of connection metrcis
				int	getSocketTimeout()
					Returns the socket timeout value.
				boolean	isOpen()
					Checks if this connection is open.
				boolean	isStale()

				void	setSocketTimeout(int timeout)
					Sets the socket timeout value.
				void	shutdown()
