Method Detail

join

MulticastMessageChannel.Key join(InetAddress group,
                                 NetworkInterface iface)
                          throws IOException

Join a multicast group to begin receiving all datagrams sent to the group. A multicast channel may join several multicast groups, including the same group on more than one interface. An implementation may impose a limit on the number of groups that may be joined at the same time.

Parameters:

group - the multicast address to join

iface - the network interface to join on

Returns:

a new key

Throws:

IOException - if an I/O error occurs

IllegalStateException - if the channel is already a member of the group on this interface

IllegalArgumentException - if the group parameters is not a multicast address, or is an unsupported address type

SecurityException - if a security manager is set, and its SecurityManager.checkMulticast(InetAddress) method denies access to the group

join

MulticastMessageChannel.Key join(InetAddress group,
                                 NetworkInterface iface,
                                 InetAddress source)
                          throws IOException

Join a multicast group to begin receiving all datagrams sent to the group from a given source address. A multicast channel may join several multicast groups, including the same group on more than one interface. An implementation may impose a limit on the number of groups that may be joined at the same time.

Parameters:

group - the multicast address to join

iface - the network interface to join on

source - the source address to listen for

Returns:

a new key

Throws:

IOException - if an I/O error occurs

IllegalStateException - if the channel is already a member of the group on this interface

IllegalArgumentException - if the group parameters is not a multicast address, or is an unsupported address type

SecurityException - if a security manager is set, and its SecurityManager.checkMulticast(InetAddress) method denies access to the group

UnsupportedOperationException - if the implementation does not support source filtering
