Method Detail

getLocalLearningObjectives

public void getLocalLearningObjectives(java.util.Vector learnObjVector)

Overrides Operator.getLocalLearningObjectives()

Overrides:

getLocalLearningObjectives in class Operator

evaluate

public Value evaluate()

Description copied from class: Assignment

Method to detect any errors before subclasses evaluate expressions Not to be used by client. Checks if LHS is a variable, and RHS evaluates correctly

Overrides:

evaluate in class Assignment

explain

public void explain(java.util.Vector explanation,
                    java.util.Vector errors)

Textually explains the evaluation of the tree - as opposed to graphical explanation by the view

Overrides:

explain in class Operator

main

public static void main(java.lang.String[] args)
