| /** |
| * A class that represents an SCTP association. |
| * |
| * <P> An association exists between two SCTP endpoints. Each endpoint is |
| * represented by a list of transport addresses through which that endpoint can |
| * be reached and from which it will originate SCTP messages. The association |
| * spans over all of the possible source/destination combinations which may be |
| * generated from each endpoint's lists of addresses. |
| * |
| * <P> Associations are identified by their Association ID. |
| * Association ID's are guaranteed to be unique for the lifetime of the |
| * association. An association ID may be reused after the association has been |
| * shutdown. An association ID is not unique across multiple SCTP channels. |
| * An Association's local and remote addresses may change if the SCTP |
| * implementation supports <I>Dynamic Address Reconfiguration</I> as defined by |
| * <A HREF="http://tools.ietf.org/html/rfc5061">RFC5061</A>, see the |
| * {@code bindAddress} and {@code unbindAddress} methods of {@link SctpChannel}, |
| * {@link SctpServerChannel}, and {@link SctpMultiChannel}. |
| * |
| * <P> An {@code Association} is returned from an {@link |
| * SctpChannel#association SctpChannel} or an {@link |
| * SctpMultiChannel#associations SctpMultiChannel}, as well |
| * as being given as a parameter to {@link NotificationHandler |
