compare
public int compare(java.lang.Object a,
java.lang.Object b)
Compare two AtomicValue objects according to the rules for their data type. UntypedAtomic
values are compared as if they were strings; if different semantics are wanted, the conversion
must be done by the caller.
- Specified by:
compare
in interface java.util.Comparator
- Parameters:
a
- the first object to be compared. It is intended that this should normally be an instance
of AtomicValue, though this restriction is not enforced. If it is a StringValue, the
collator is used to compare the values, otherwise the value must implement the java.util.Comparable
interface.
b
- the second object to be compared. This must be comparable with the first object: for
example, if one is a string, they must both be strings.
- Returns:
- <0 if a0 if a>b
- Throws:
java.lang.ClassCastException
- if the objects are not comparable
