Constructor Details

DefaultClientConnectionOperator

public DefaultClientConnectionOperator(SchemeRegistry schemes)

Creates a new client connection operator for the given scheme registry.

Parameters:

schemes - the scheme registry

Method Details

createConnection

public OperatedClientConnection createConnection()

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

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

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

prepareSocket

protected void prepareSocket(Socket sock,
HttpContext context,
HttpParams params)
                      throws IOException

Performs standard initializations on a newly created socket.

Parameters:

sock - the socket to prepare

context - the context for the connection

params - the parameters from which to prepare the socket

Throws:

IOException - in case of an IO problem
