io.deephaven.base.stats.Value

io.deephaven.base.stats.Composite

public class Composite
extends Value

A statistic that represents the composite or rolled-up value of a set of child statistics, as best as possible. This statistic cannot be sample(long)d or Value.increment(long)ed. Currently, calls to update(io.deephaven.base.stats.Item, io.deephaven.base.stats.ItemUpdateListener, long, long, long) are silently ignored, which also means that Composites are not logged. Thus a Composite is currently only useful for summaries in web/JMX displays.
