IntComparatorChain (tablesaw-core 0.44.1 API)

java.lang.Object
- tech.tablesaw.sorting.comparators.IntComparatorChain

All Implemented Interfaces:

it.unimi.dsi.fastutil.ints.IntComparator, Serializable, Comparator<Integer>
```
public class IntComparatorChain
extends Object
implements it.unimi.dsi.fastutil.ints.IntComparator, Serializable
```
An IntComparator that wraps one or more Comparators in sequence. The ComparatorChain calls each Comparator in sequence until either 1) any single Comparator returns a non-zero result (and that result is then returned), or 2) the ComparatorChain is exhausted (and zero is returned)
The implementation is based on Apache Commons Collections
