public class MathlibEvent

extends java.lang.Object

A MathlibEvent is fired whenever a variable is created, deleted or changes it's value. With this mechanism all listeners are notified about a change in the Mathlib scope. The event is usually fired by the Parse class, but exceptionally as well in the jaQuzzi program.
