public PlainSocketFactory()

Method Detail

getSocketFactory

public static PlainSocketFactory getSocketFactory()

Gets the default factory. Usually there should be no reason for creating multiple instances of this class.

Returns:

the default factory

createSocket

public Socket createSocket()

Description copied from interface: SocketFactory

Creates a new, unconnected socket. The socket should subsequently be passed to connectSocket.

Specified by:

createSocket in interface SocketFactory

Returns:

a new socket

connectSocket

public Socket connectSocket(Socket sock,
                            String host,
                            int port,
                            InetAddress localAddress,
                            int localPort,
                            HttpParams params)
                     throws IOException

Description copied from interface: SocketFactory

Connects a socket to the given host.

Specified by:

connectSocket in interface SocketFactory

Parameters:

sock - the socket to connect, as obtained from createSocket. null indicates that a new socket should be created and connected.

host - the host to connect to

port - the port to connect to on the host

localAddress - the local address to bind the socket to, or null for any

localPort - the port on the local machine, 0 or a negative number for any

params - additional parameters for connecting

Returns:

the connected socket. The returned object may be different from the sock argument if this factory supports a layered protocol.

Throws:

IOException - if an I/O error occurs

UnknownHostException - if the IP address of the target host can not be determined

ConnectTimeoutException - if the socket cannot be connected within the time limit defined in the params

isSecure

public final boolean isSecure(Socket sock)
                       throws IllegalArgumentException

Checks whether a socket connection is secure. This factory creates plain socket connections which are not considered secure.

Specified by:

isSecure in interface SocketFactory

Parameters:

sock - the connected socket

Returns:

false

Throws:

IllegalArgumentException - if the argument is invalid
