@Deprecated public interface SocketFactory
|Modifier and Type||Method and Description|
Connects a socket to the given host.
Creates a new, unconnected socket.
Checks whether a socket provides a secure connection.
java.net.Socket createSocket() throws java.io.IOException
java.io.IOException- if an I/O error occurs while creating the socket
java.net.Socket connectSocket(java.net.Socket sock, java.lang.String host, int port, java.net.InetAddress localAddress, int localPort, HttpParams params) throws java.io.IOException, java.net.UnknownHostException, ConnectTimeoutException
sock- the socket to connect, as obtained from
nullindicates 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
localPort- the port on the local machine, 0 or a negative number for any
sockargument if this factory supports a layered protocol.
java.io.IOException- if an I/O error occurs
java.net.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
boolean isSecure(java.net.Socket sock) throws java.lang.IllegalArgumentException
connectedby 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.
sock- the connected socket to check
trueif the connection of the socket should be considered secure, or
falseif it should not
java.lang.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.
