Examples of AtomicComparer

client.net.sf.saxon.ce.expr.sort.AtomicComparer
Interface representing an object that can be used to compare two XPath atomic values for equality or for ordering.
net.sf.saxon.sort.AtomicComparer
A Comparator used for comparing atomic values of arbitrary item types. It encapsulates a Collator that is used when the values to be compared are strings. It also supports a separate method for testing equality of items, which can be used for data types that are not ordered. @author Michael H. Kay
