bind method Null safety
Listens on a given address and port.
When the returned future completes the server socket is bound
to the given address
and port
and has started listening on it.
The address
can either be a String or an
InternetAddress. If address
is a String, bind will
perform a InternetAddress.lookup and use the first value in the
list. To listen on the loopback adapter, which will allow only
incoming connections from the local host, use the value
InternetAddress.loopbackIPv4 or
InternetAddress.loopbackIPv6. To allow for incoming
connection from the network use either one of the values
InternetAddress.anyIPv4 or InternetAddress.anyIPv6 to
bind to all interfaces or the IP address of a specific interface.
If an IP version 6 (IPv6) address is used, both IP version 6
(IPv6) and version 4 (IPv4) connections will be accepted. To
restrict this to version 6 (IPv6) only, use v6Only
to set
version 6 only.
If port
has the value 0
an ephemeral port will
be chosen by the system. The actual port used can be retrieved
using the port
getter.
The optional argument backlog
can be used to specify the listen
backlog for the underlying OS listen setup. If backlog
has the
value of 0
(the default) a reasonable value will be chosen by
the system.
The optional argument shared
specifies whether additional RawServerSocket
objects can bind to the same combination of address
, port
and v6Only
.
If shared
is true
and more RawServerSocket
s from this isolate or
other isolates are bound to the port, then the incoming connections will be
distributed among all the bound RawServerSocket
s. Connections can be
distributed over multiple isolates this way.
Implementation
external static Future<RawServerSocket> bind(address, int port,
{int backlog = 0, bool v6Only = false, bool shared = false});
