Interface SocketFactory

All Known Subinterfaces:
LayeredSocketFactory
All Known Implementing Classes:
MultihomePlainSocketFactory, PlainSocketFactory, SSLSocketFactory

Deprecated. (4.1) use SchemeSocketFactory

@Deprecated
public interface SocketFactory

A factory for creating, initializing and connecting sockets. The factory encapsulates the logic for establishing a socket connection.

Since:
4.0

Method Summary
 Socket connectSocket(Socket sock, String host, int port, InetAddress localAddress, int localPort, HttpParams params)
          Deprecated. Connects a socket to the given host.
 Socket createSocket()
          Deprecated. Creates a new, unconnected socket.
 boolean isSecure(Socket sock)
          Deprecated. Checks whether a socket provides a secure connection.
 

Method Detail

createSocket

Socket createSocket()
                    throws IOException
Deprecated. 
Creates a new, unconnected socket. The socket should subsequently be passed to connectSocket.

Returns:
a new socket
Throws:
IOException - if an I/O error occurs while creating the socket

connectSocket

Socket connectSocket(Socket sock,
                     String host,
                     int port,
                     InetAddress localAddress,
                     int localPort,
                     HttpParams params)
                     throws IOException,
                            UnknownHostException,
                            ConnectTimeoutException
Deprecated. 
Connects a socket to the given host.

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

boolean isSecure(Socket sock)
                 throws IllegalArgumentException
Deprecated. 
Checks whether a socket provides a secure connection. The socket must be connected by this factory. The factory will not perform I/O operations in this method.

As a rule of thumb, plain sockets are not secure and TLS/SSL sockets are secure. However, there may be application specific deviations. For example, a plain socket to a host in the same intranet ("trusted zone") could be considered secure. On the other hand, a TLS/SSL socket could be considered insecure based on the cipher suite chosen for the connection.

Parameters:
sock - the connected socket to check
Returns:
true if the connection of the socket should be considered secure, or false if it should not
Throws:
IllegalArgumentException - if the argument is invalid, for example because it is not a connected socket or was created by a different socket factory. Note that socket factories are not required to check these conditions, they may simply return a default value when called with an invalid socket argument.
