Interface SchemaComparable

All Superinterfaces:

java.lang.Comparable<SchemaComparable>

public interface SchemaComparable
extends java.lang.Comparable<SchemaComparable>

A Comparable value that implements the XML Schema ordering comparison semantics for this value.

In the case of data types that are partially ordered, the returned Comparable extends the standard semantics of the compareTo() method by returning the value SequenceTool.INDETERMINATE_ORDERING when there is no defined order relationship between two given values.

As well as implementing Comparable.compareTo(T), a SchemaComparable must also provide compatible implementations of equals() and hashCode(), to allow XSD uniqueness constraints to be implemented by maintaining a hash table of SchemaComparable objects
