public DefaultClientConnection()

Deprecated.

Method Detail

getId

public String getId()

Deprecated.

Description copied from interface: ManagedHttpClientConnection

Returns connection ID which is expected to be unique for the life span of the connection manager.

Specified by:

getId in interface ManagedHttpClientConnection

getTargetHost

public final HttpHost getTargetHost()

Deprecated.

Description copied from interface: OperatedClientConnection

Obtains the target host for this connection. If the connection is to a proxy but not tunnelled, this is the proxy. If the connection is tunnelled through a proxy, this is the target of the tunnel.

The return value is well-defined only while the connection is open. It may change even while the connection is open, because of an update.

Specified by:

getTargetHost in interface OperatedClientConnection

Returns:

the host to which this connection is opened

isSecure

public final boolean isSecure()

Deprecated.

Description copied from interface: OperatedClientConnection

Indicates whether this connection is secure. The return value is well-defined only while the connection is open. It may change even while the connection is open, because of an update.

Specified by:

isSecure in interface OperatedClientConnection

Returns:

true if this connection is secure, false otherwise

getSocket

public final Socket getSocket()

Deprecated.

Description copied from interface: OperatedClientConnection

Obtains the socket for this connection. The return value is well-defined only while the connection is open. It may change even while the connection is open, because of an update.

Specified by:

getSocket in interface ManagedHttpClientConnection

Specified by:

getSocket in interface OperatedClientConnection

Overrides:

getSocket in class SocketHttpClientConnection

Returns:

the socket for communicating with the target host

getSSLSession

public SSLSession getSSLSession()

Deprecated.

Description copied from interface: ManagedHttpClientConnection

Obtains the SSL session of the underlying connection, if any. If this connection is open, and the underlying socket is an SSLSocket, the SSL session of that socket is obtained. This is a potentially blocking operation.

Specified by:

getSSLSession in interface ManagedHttpClientConnection

Returns:

the underlying SSL session if available, null otherwise

opening

public void opening(Socket sock,
           HttpHost target)
             throws IOException

Deprecated.

Description copied from interface: OperatedClientConnection

Signals that this connection is in the process of being open.

By calling this method, the connection can be re-initialized with a new Socket instance before OperatedClientConnection.openCompleted(boolean, org.apache.http.params.HttpParams) is called. This enabled the connection to close that socket if shutdown is called before it is fully open. Closing an unconnected socket will interrupt a thread that is blocked on the connect. Otherwise, that thread will either time out on the connect, or it returns successfully and then opens this connection which was just shut down.

This method can be called multiple times if the connection is layered over another protocol. Note: This method will not close the previously used socket. It is the caller's responsibility to close that socket if it is no longer required.

The caller must invoke OperatedClientConnection.openCompleted(boolean, org.apache.http.params.HttpParams) in order to complete the process.

Specified by:

opening in interface OperatedClientConnection

Parameters:

sock - the unconnected socket which is about to be connected.

target - the target host of this connection

Throws:

IOException

openCompleted

public void openCompleted(boolean secure,
                 HttpParams params)
                   throws IOException

Deprecated.

Description copied from interface: OperatedClientConnection

Signals that the connection has been successfully open. An attempt to call this method on an open connection will cause an exception.

Specified by:

openCompleted in interface OperatedClientConnection

Parameters:

secure - true if this connection is secure, for example if an SSLSocket is used, or false if it is not secure

params - parameters for this connection. The parameters will be used when creating dependent objects, for example to determine buffer sizes.

Throws:

IOException

shutdown

public void shutdown()
              throws IOException

Deprecated.

Force-closes this connection. If the connection is still in the process of being open (the method opening was already called but openCompleted was not), the associated socket that is being connected to a remote address will be closed. That will interrupt a thread that is blocked on connecting the socket. If the connection is not yet open, this will prevent the connection from being opened.

Specified by:

shutdown in interface HttpConnection

Overrides:

shutdown in class SocketHttpClientConnection

Throws:

IOException - in case of a problem

close

public void close()
           throws IOException

Deprecated.

Specified by:

close in interface Closeable

Specified by:

close in interface AutoCloseable

Specified by:

close in interface HttpConnection

Overrides:

close in class SocketHttpClientConnection

Throws:

IOException

                                          HttpParams params)
                                               throws IOException

Deprecated.

Overrides:

Throws:

IOException

protected SessionOutputBuffer createSessionOutputBuffer(Socket socket,
                                            int buffersize,
                                            HttpParams params)
                                                 throws IOException

Deprecated.

Throws:

IOException

createResponseParser

protected HttpMessageParser<HttpResponse> createResponseParser(SessionInputBuffer buffer,
                                                   HttpResponseFactory responseFactory,
                                                   HttpParams params)

Deprecated.

createResponseParser in class AbstractHttpClientConnection

bind

public void bind(Socket socket)
          throws IOException

Deprecated.

Description copied from interface: ManagedHttpClientConnection

Binds this connection to the given socket. The connection is considered open if it is bound and the underlying socket is connection to a remote host.

Specified by:

bind in interface ManagedHttpClientConnection

Parameters:

socket - the socket to bind the connection to.

Throws:

IOException

update

public void update(Socket sock,
          HttpHost target,
          boolean secure,
          HttpParams params)
            throws IOException

Deprecated.

Description copied from interface: OperatedClientConnection

Updates this connection. A connection can be updated only while it is open. Updates are used for example when a tunnel has been established, or when a TLS/SSL connection has been layered on top of a plain socket connection.

Note: Updating the connection will not close the previously used socket. It is the caller's responsibility to close that socket if it is no longer required.

Specified by:

update in interface OperatedClientConnection

Parameters:

sock - the new socket for communicating with the target host, or null to continue using the old socket. If null is passed, helper objects that depend on the socket should be re-used. In that case, some changes in the parameters will not take effect.

target - the new target host of this connection

secure - true if this connection is now secure, false if it is not secure

params - new parameters for this connection

Throws:

IOException
