Method Detail

setReceiverFactory

public void setReceiverFactory(org.apache.http.io.HttpDataReceiverFactory rcvfactory)

---

public void setTransmitterFactory(org.apache.http.io.HttpDataTransmitterFactory trxfactory)

---

bind

protected void bind(java.net.Socket socket,
                    org.apache.http.params.HttpParams params)
             throws java.io.IOException

---

isOpen

public boolean isOpen()

Description copied from interface: org.apache.http.HttpConnection

Checks if this connection is open.

Specified by:

isOpen in interface org.apache.http.HttpConnection

---

shutdown

public void shutdown()
              throws java.io.IOException

Description copied from interface: org.apache.http.HttpConnection

This method will force close the connection. This is the only method, which may be called from a different thread to terminate the connection. This method will not attempt to flush the transmitter's internal buffer prior to closing the underlying socket.

Specified by:

shutdown in interface org.apache.http.HttpConnection

---

close

public void close()
           throws java.io.IOException

Description copied from interface: org.apache.http.HttpConnection

This method will gracefully close the connection. It will attempt to flush the transmitter's internal buffer prior to closing the underlying socket. This method MAY NOT be called from a different thread to force shutdown the connection. Use #shutdown() instead.

Specified by:

close in interface org.apache.http.HttpConnection

---

isStale

public boolean isStale()

Description copied from interface: org.apache.http.HttpConnection

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 indefinite time before returning a result.

Specified by:

isStale in interface org.apache.http.HttpConnection
