DoublePredicate

public static class DoublePredicate.MergeRowsOr
extends java.lang.Object

In case of an AND between two conditions, the views have to be merged so that the result view contains the union of the rows indices of the views. This is accomplished: 1) copying to the result view all the indices of the first view 2) copying to the result view the indices of the second view that are not in the first view
