public class EvaluationException

extends java.lang.RuntimeException

This is an exception which is thrown when evaluating an expression or function causes an exception to be thrown in Java. Rather than showing the stack trace for the JVM, we want to provide the user with a stack trace of the expression evaluation. This involves functions, expressions being potentially deeply nested. The information should be available using the tree structure of the expressions.
