org.apache.http.conn.scheme.SocketFactory |
Known Indirect Subclasses |
A factory for creating and connecting sockets.
The factory encapsulates the logic for establishing a socket connection.
Both
Object.equals()
and
Object.hashCode()
must be overridden for the correct operation of some connection managers.

Connects a socket to the given host.

Connects a socket to the given host.
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 |

argument if this factory supports
a layered protocol.
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
|
Creates a new, unconnected socket.
The socket should subsequently be passed to
connectSocket
.
IOException | if an I/O error occurs while creating the socket |
---|
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 cypher suite chosen for the connection.
sock | the connected socket to check |
---|
true
if the connection of the socket
should be considered secure, or
false
if it should not
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. |
