connect static method
Creates a new socket connection to the host and port.
Returns a Future that will complete with either a RawSocket once connected, or an error if the host-lookup or connection failed.
The host
can either be a String or an InternetAddress. If host
is a
String, connect will perform a InternetAddress.lookup and try
all returned InternetAddresses, until connected. If IPv4 and IPv6
addresses are both available then connections over IPv4 are preferred. If
no connection can be established then the error from the first failing
connection is returned.
The argument sourceAddress
can be used to specify the local
address to bind when making the connection. The sourceAddress
can either
be a String or an InternetAddress. If a String is passed it must
hold a numeric IP address.
The sourcePort
defines the local port to bind to. If sourcePort
is
not specified or zero, a port will be chosen.
The argument timeout
is used to specify the maximum allowed time to wait
for a connection to be established. If timeout
is longer than the system
level timeout duration, a timeout may occur sooner than specified in
timeout
. On timeout, a SocketException is thrown and all ongoing
connection attempts to host
are cancelled.
