325N/A/**
325N/A * This class has HA information
325N/A * <p>
325N/A *
325N/A * This would help a loadbalancer to put the request(in case of a fail-over)
325N/A * on a replica instance that has all the related data. Even if there is no
325N/A * loadbalancer, a backing store could locate the information by directly
325N/A * going to the correct replica instance. This would also help any part of
325N/A * the runtime to know about failover case(and in-turn may invalidate
325N/A * local caches).
325N/A *
325N/A * <p>
325N/A * To achieve this functionality, it carries two pieces of information:
325N/A * <ol>
325N/A * <li>key - Related {@link com.sun.org.glassfish.ha.store.api.BackingStore} keys can
325N/A * use this info for their HashableKey impl. First store creates this object,
325N/A * and subsequent related stores use the same key.
325N/A * <li>replicaInstance - where the related info is replicated
325N/A * </ol>
325N/A *
325N/A * <p>
325N/A * This can be accessed from {@link Packet} using {@link Packet#HA_INFO}
325N/A * property by the runtime. This object is created typically
325N/A * <ul>
325N/A * <li> When a store happens for the first time
325N/A * <li> A subsequent inbound transport creates from cookies
325N/A * <li> A fail-over request stores the data to a different replica
325N/A * </ul>
