Examples of mondrian.rolap.agg.SegmentCacheManager$PeekCommand

mondrian.rolap.agg.SegmentCacheManager
Locates segments in the cache that satisfy a given request.
The result consists of (a) a list of segment headers, (b) a list of futures for segment bodies that are currently being loaded, (c) converters to convert headers into {@link SegmentWithData}.

For (a), the client should call the cache to get the body for each segment header; it is possible that there is no body in the cache. For (b), the client will have to wait for the segment to arrive.

    {
        final List<RolapStar> starList = getStarList(region);
        for (RolapStar star : starList) {
            star.print(pw, "", false);
        }
        final SegmentCacheManager manager =
            MondrianServer.forConnection(connection)
                .getAggregationManager().cacheMgr;
        Locus.execute(
            connection,
            "CacheControlImpl.printCacheState",
            new Locus.Action<Void>() {
                public Void execute() {
                    manager.printCacheState(region, pw, Locus.peek());
                    return null;
                }
            });
