org.apache.jackrabbit.oak.plugins.observation.EventHandler
Handler of content change events. Used to decouple processing of changes from the content diff logic that detects them.
As the content diff recurses down the content tree, it will call the {@link #getChildHandler(String,NodeState,NodeState)} method tospecialize the handler instance for each node under which changes are detected. The other handler methods always apply to the properties and direct children of the node for which that handler instance is specialized. The handler is expected to keep track of contextual information like the path or identifier of the current node based on the sequence of those specialization calls.
All names and paths passed to handler methods use unmapped Oak names.

            @Nonnull Iterable<String> basePaths, @Nonnull EventFilter filter) {

        EventFactory factory = new EventFactory(mapper, info);
        EventHandler handler = new FilteredHandler(
                filter, new QueueingHandler(this, factory, before, after));
        for (String path : basePaths) {
            addHandler(before, after, path, handler, generator);
        }
