StringComparator (Starjava Datanode API)

java.lang.Object
- uk.ac.starlink.datanode.nodes.StringComparator

All Implemented Interfaces:

java.util.Comparator
```
public class StringComparator
extends java.lang.Object
implements java.util.Comparator
```
A very simple implementation of the Comparator interface. It is suitable for use on any objects for which the toString method provides a suitable basis for object comparison.
You might think that calling java.text.Collator.getInstance ought to provide much the same thing; however that gives you a compare method which casts to String rather than calling the toString method on its arguments, leading to a ClassCastException in most useful cases. I wonder why it does that?
