ComparisonException (saxon JavaDoc)

java.lang.Object
- java.lang.Throwable
- - java.lang.Exception
  - - java.lang.RuntimeException
    - - java.lang.ClassCastException
      - net.sf.saxon.expr.sort.ComparisonException

All Implemented Interfaces:

Serializable
```
public class ComparisonException
extends ClassCastException
```
A ComparisonException is a ClassCastException that encapsulates an XPathException. It is used because the compareTo method is defined to return ClassCastException when values are not comparable; using a ClassCastException that encapsulates XPath error information enables us to return the correct error code, and to distinguish dynamic errors from type errors.
