CellComparator
public final class DefaultCellComparator extends AbstractCellComparator
A default cell comparator.Verifies that the objects being compared are the same class. Looks to see if the objects being compared implement comparable and, if so, delegates to that; otherwise, implements a lexicographical compare function (i.e. string sorting). Uses the objects' toString() method and then compares the resulting strings. Note that null values are acceptable and are considered "smaller" than any non-null value.
