socketAddress
- the address of a node as returned by Cassandra. Note that
if the rpc_address
of a node has been configured to 0.0.0.0
server side, then the provided address will be the node listen_address
,
*not* 0.0.0.0
. Also note that the port for InetSocketAddress
will always be the one set at Cluster construction time (9042 by default).address
. If the return is null
, then address
will be used by the driver (it is thus equivalent to returing
address
directly)public void close()
