/**
 * A selectable channel for message-oriented SCTP sockets.
 *
 * <P> An SCTP multi channel supports many associations on a single socket.
 * An {@code SctpMultiChannel} is created by invoking the
 * {@link #open open} method of this class. A newly-created channel is open but
 * not yet bound. An attempt to invoke the {@link #receive receive} method of an
 * unbound channel will cause the {@link NotYetBoundException}
 * to be thrown. An attempt to invoke the {@link #send send} method of an
 * unbound channel will cause it to first invoke the {@link #bind bind} method.
 * The address(es) that the channel's socket is bound to can be retrieved by
 * calling {@link #getAllLocalAddresses getAllLocalAddresses}.
 *
 * <P> Messages may be sent and received without explicitly setting up an
 * association with the remote peer. The channel will implicitly setup
 * a new association whenever it sends or receives a message from a remote
 * peer if there is not already an association with that peer. Upon successful
 * association setup, an {@link AssociationChangeNotification
 * association changed} notification will be put to the SCTP stack with its
 * {@code event} parameter set to {@link
 * AssociationChangeNotification.AssocChangeEvent#COMM_UP
 * COMM_UP}. This notification can be received by invoking {@link #receive
 * receive}.
 *
 * <P> Socket options are configured using the
 * {@link #setOption(SctpSocketOption,Object,Association) setOption} method. An
 * {@code SctpMultiChannel} supports the following options:

     *
     * <P> If this method receives a message it is copied into the given byte
     * buffer and an {@link MessageInfo} is returned.
     * The message is transferred into the given byte buffer starting at its
     * current position and the buffers position is incremented by the number of
     * bytes read. If there are fewer bytes remaining in the buffer than are
     * required to hold the message, or the underlying input buffer does not

     * MessageInfo#isComplete isComplete} on the returned {@code
     * MessageInfo} will return {@code false}, and more invocations of this

     * one message at a time will be partially delivered in any stream. The
     * socket option {@link SctpStandardSocketOptions#SCTP_FRAGMENT_INTERLEAVE
     * SCTP_FRAGMENT_INTERLEAVE} controls various aspects of what interlacing of
     * messages occurs.
     *
     * <P> If this method receives a notification then the appropriate method of
     * the given handler, if there is one, is invoked. If the handler returns {@link
     * HandlerResult#CONTINUE CONTINUE} then this method will try to receive another
     * message/notification, otherwise, if {@link HandlerResult#RETURN RETURN} is returned
     * this method will return {@code null}. If an uncaught exception is thrown by the
     * handler it will be propagated up the stack through this method.
     *
     * <P> If a security manager has been installed then for each new association
     * setup this method verifies that the associations source address and port
     * number are permitted by the security manager's {@link

     * to enforce the above synchronization policy, that way handlers
     * will not stall other threads from receiving. A handler should not invoke
     * the {@code receive} method of this channel, if it does an
