All Implemented Interfaces:

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

Enclosing class:

FrameTestUtil

public static class FrameTestUtil.CountIntValueRows
extends water.MRTask<FrameTestUtil.CountIntValueRows>

Look for the number of times a particular value (integer) appears in a column of a dataframel. The columnInd is where you expect your value to be found and columnIndRowValue is the column ID which identifies your actual data row number where that value is found.
