AlphaNumericComparator (Stardog-10.2.1 API)

java.lang.Object
- com.complexible.common.util.AlphaNumericComparator<T>

All Implemented Interfaces:

java.util.Comparator<T>
```
public class AlphaNumericComparator<T>
extends java.lang.Object
implements java.util.Comparator<T>
```
This is a comparator to perform a mix of alphabetical+numeric comparison. For example, if there is a list {"test10", "test2", "test150", "test25", "test1"} then what we generally expect from the ordering is the result {"test1", "test2", "test10", "test25", "test150"}. However, standard lexigraphic ordering does not do that and "test10" comes before "test2". This class is provided to overcome that problem. This functionality is useful to sort the benchmark files (like the ones in in DL-benchmark-suite) from smallest to the largest. Comparisons are done on the String values returned by toString() so care should be taken when this comparator is used to sort arbitrary Java objects.
