All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.concurrent.Future<java.lang.Void>, jsr166y.ForkJoinPool.ManagedBlocker, water.Freezable<MetaCollector.DynamicHisto>

Enclosing class:

MetaCollector

public static final class MetaCollector.DynamicHisto
extends water.MRTask<MetaCollector.DynamicHisto>

A wrapper class around DHistogram. NB: _sums and _ssqs are not the same as those found in DHistogram instances. The difference being that these are compounded over the column data, rather than over the target column.
