Methods

boolean BindLocalPort(in long port)

long GetLocalPort()

boolean JoinMulticastGroup(in DOMString group)

boolean SendTo(in DOMString dest, in long port, in ArrayBufferView data)

boolean SendTo(in DOMString dest, in long port, in DOMString data)

void Close()

Shuts down the instance, preventing it from further consuming resources. If this method is not called, garbage collection determines when the instance will be destroyed.
