Examples of com.sun.appserv.ha.util.CompositeMetadata

com.sun.appserv.ha.util.CompositeMetadata
A class to hold a collection of children SessionAttributeMetadata. This class is used mainly to store a collection of AttributeMetaData that are part of a WebSession. The metadata about the web session itself can be obtained directly from the CompositeMetadata itself, while the metadata of its attributes can be obtained from the individual SessionAttributeMetadata that is part of the collection returned by getEntries().

    public static CompositeMetadata createCompositeMetadataFrom(ReplicationState state) {
        if (state == null || state.getState() == null) {
            return null;
        }
        Collection entries = deserializeStatesCollection(state.getState());
        CompositeMetadata result
            = new CompositeMetadata(
                state.getVersion(),  //version
                state.getLastAccess(), //lastAccess
                state.getMaxInactiveInterval(), //maxInactive
                entries,                        //entries
                state.getTrunkState(),          //trunkState
