public abstract class ParseableGPNode
extends ec.gp.GPNode
implements ParseableNode

An abstract class which allows us to save a node and run it again at a later time. It is able to interface the GP node class with the parseableNode class. The only code that your GP code needs to make is to add the "getJavaCode()" function to your class and implement this abstract class.
