Class NumericComparer11
java.lang.Object
net.sf.saxon.expr.sort.NumericComparer
net.sf.saxon.expr.sort.NumericComparer11
- All Implemented Interfaces:
- Serializable, AtomicComparer
public class NumericComparer11
- extends NumericComparer
A Comparer used for comparing sort keys when data-type="number". The items to be
compared are converted to numbers, and the numbers are then compared directly. NaN values
compare equal to each other, and equal to an empty sequence, but less than anything else.
This class is used in XSLT only, so there is no need to handle XQuery's "empty least" vs
"empty greatest" options.
