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

com.sun.appserv.ha.util.SessionAttributeMetadata
AttributeMetadata contains the metadata of an attribute that is part of an Http Session. When a container decides to save a session it passes an instance of CompositeMetaData which contains a collection of AttributeMetadata.
The attribute in question could have been deleted, or modified or could be a new attribute inside the HttpSession. getOperation() tells exactly what operation needs to be performed for this attribute
The attribute state/data itself can be obtained with getState(). Since an attribute is part of a session, the attributes must be deleted when the session is removed. The CompositeMetadata contains the last access time and inactive timeout for the session. @see CompositeMetadata

    private CompositeMetadata applyCompositeMetadataDeltas(CompositeMetadata current, CompositeMetadata deltas) {
        Collection<SessionAttributeMetadata> currentCollection = current.getEntries();
        Collection<SessionAttributeMetadata> deltasCollection = deltas.getEntries();
        Iterator deltasIterator = deltasCollection.iterator();
        while(deltasIterator.hasNext()) {
            SessionAttributeMetadata nextAttributeMetadata
                = (SessionAttributeMetadata)deltasIterator.next();
            this.applyCompositeMetadataDelta(nextAttributeMetadata, currentCollection);
        }
        return current;
    }
