@Deprecated
@Contract(threading=SAFE_CONDITIONAL)
public class DefaultClientConnectionOperator
extends Object
implements ClientConnectionOperator

Deprecated.

(4.3) use PoolingHttpClientConnectionManager.

Default implementation of a ClientConnectionOperator. It uses a SchemeRegistry to look up SchemeSocketFactory objects.

This connection operator is multihome network aware and will attempt to retry failed connects against all known IP addresses sequentially until the connect is successful or all known addresses fail to respond. Please note the same CoreConnectionPNames.CONNECTION_TIMEOUT value will be used for each connection attempt, so in the worst case the total elapsed time before timeout can be CONNECTION_TIMEOUT * n where n is the number of IP addresses of the given host. One can disable multihome support by overriding the resolveHostname(String) method and returning only one IP address for the given host name.

The following parameters can be used to customize the behavior of this class:

• CoreProtocolPNames.HTTP_ELEMENT_CHARSET
• CoreConnectionPNames.SO_TIMEOUT
• CoreConnectionPNames.SO_LINGER
• CoreConnectionPNames.SO_REUSEADDR
• CoreConnectionPNames.TCP_NODELAY
• CoreConnectionPNames.SOCKET_BUFFER_SIZE
• CoreConnectionPNames.CONNECTION_TIMEOUT
• CoreConnectionPNames.MAX_LINE_LENGTH

Since:

4.0

Method Detail

createConnection

public OperatedClientConnection createConnection()

Deprecated.

Description copied from interface: ClientConnectionOperator

Creates a new connection that can be operated.

Specified by:

createConnection in interface ClientConnectionOperator

Returns:

a new, unopened connection for use with this operator

openConnection

public void openConnection(OperatedClientConnection conn,
                           HttpHost target,
                           InetAddress local,
                           HttpContext context,
                           HttpParams params)
                    throws IOException

Deprecated.

Description copied from interface: ClientConnectionOperator

Opens a connection to the given target host.

Specified by:

openConnection in interface ClientConnectionOperator

Parameters:

conn - the connection to open

target - the target host to connect to

local - the local address to route from, or null for the default

context - the context for the connection

params - the parameters for the connection

Throws:

IOException - in case of a problem

updateSecureConnection

public void updateSecureConnection(OperatedClientConnection conn,
                                   HttpHost target,
                                   HttpContext context,
                                   HttpParams params)
                            throws IOException

Deprecated.

Description copied from interface: ClientConnectionOperator

Updates a connection with a layered secure connection. The typical use of this method is to update a tunnelled plain connection (HTTP) to a secure TLS/SSL connection (HTTPS).

Specified by:

updateSecureConnection in interface ClientConnectionOperator

Parameters:

conn - the open connection to update

target - the target host for the updated connection. The connection must already be open or tunnelled to the host and port, but the scheme of the target will be used to create a layered connection.

context - the context for the connection

params - the parameters for the updated connection

Throws:

IOException - in case of a problem
