constructor - Java - Parameter declaration -


i'm studying piece of code, constructor several parameters. declaration of last parameter ... mean?

    /**  * public constructor.  * @param serviceport service port  * @param nodeaddresses node addresses  * @param sessionaware true if server aware of sessions, false otherwise  * @throws nullpointerexception if given socket-addresses array null  * @throws illegalargumentexception if given service port outside range [0, 0xffff],  *    or given socket-addresses array empty  * @throws ioexception if given port in use, or cannot bound  */ public tcpswitch(final int serviceport, final boolean sessionaware, final inetsocketaddress... nodeaddresses) throws ioexception {     super();     if (nodeaddresses.length == 0) throw new illegalargumentexception();      this.servicesocket = new serversocket(serviceport);     this.executorservice = executors.newcachedthreadpool();     this.nodeaddresses = nodeaddresses;     this.sessionaware = sessionaware;      // start acceptor thread     final thread thread = new thread(this, "tcp-acceptor");     thread.setdaemon(true);     thread.start(); }

it called varargs, here more http://docs.oracle.com/javase/1.5.0/docs/guide/language/varargs.html

the 3 periods after final parameter's type indicate final argument may passed array or sequence of arguments. varargs can used in final argument position.

as can see in code in case array.
