Class AlphaNumericComparator
java.lang.Object
org.mindswap.pellet.utils.AlphaNumericComparator
- All Implemented Interfaces:
- java.util.Comparator<java.lang.Object>
public class AlphaNumericComparator
- extends java.lang.Object
- implements java.util.Comparator<java.lang.Object>
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 lexicographic
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.
