Method Details

createSocket

public Socket createSocket(String host,
 int port,
 InetAddress localAddress,
 int localPort)
                    throws IOException,
UnknownHostException

Description copied from interface: ProtocolSocketFactory

Gets a new socket connection to the given host.

Specified by:

createSocket in interface ProtocolSocketFactory

Parameters:

host - the host name/IP

port - the port on the host

localAddress - the local host name/IP to bind the socket to

localPort - the port on the local machine

Returns:

Socket a new socket

Throws:

IOException - if an I/O error occurs while creating the socket

UnknownHostException - if the IP address of the host cannot be determined

createSocket

public Socket createSocket(String host,
 int port,
 InetAddress localAddress,
 int localPort,
 HttpConnectionParams params)
                    throws IOException,
UnknownHostException,
ConnectTimeoutException

Attempts to get a new socket connection to the given host within the given time limit.

This method employs several techniques to circumvent the limitations of older JREs that do not support connect timeout. When running in JRE 1.4 or above reflection is used to call Socket#connect(SocketAddress endpoint, int timeout) method. When executing in older JREs a controller thread is executed. The controller thread attempts to create a new socket within the given limit of time. If socket constructor does not return until the timeout expires, the controller terminates and throws an ConnectTimeoutException

Specified by:

createSocket in interface ProtocolSocketFactory

Parameters:

host - the host name/IP

port - the port on the host

localAddress - the local host name/IP to bind the socket to

localPort - the port on the local machine

params - Http connection parameters

Returns:

Socket a new socket

Throws:

IOException - if an I/O error occurs while creating the socket

UnknownHostException - if the IP address of the host cannot be determined

ConnectTimeoutException - if socket cannot be connected within the given time limit

Since:

3.0
