Method Summary

Value	evaluate() Method to detect any errors before subclasses evaluate expressions Not to be used by client Checks if LHS variable has been properly assigned
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 Tries to round up all the errors while also explaining any correct expression
void	getLocalLearningObjectives(java.util.Vector learnObjVector) Overrides Operator.getLocalLearningObjectives()
java.lang.String	getQualifiedLearningObject() Method returns the name of the operator, disambiguated enough so that it can be easily credited in the student model.

Overrides Operator.getLocalLearningObjectives()

Overrides:

getLocalLearningObjectives in class Operator

getQualifiedLearningObject

public java.lang.String getQualifiedLearningObject()

Method returns the name of the operator, disambiguated enough so that it can be easily credited in the student model.

Overrides:

getQualifiedLearningObject in class Operator

public Value evaluate()

Method to detect any errors before subclasses evaluate expressions Not to be used by client Checks if LHS variable has been properly assigned

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 Tries to round up all the errors while also explaining any correct expression

Overrides:

explain in class Operator
