Method Detail

getLocalLearningObjectives

public void getLocalLearningObjectives(java.util.Vector learnObjVector)

Description copied from class: Bitwise

Overrides Operator.getLocalLearningObjectives(). The answer being correct is a learning objective applicable to all bitwise operators. Not using integer operands is an error that applies to all bitwise operators. This is used by &, |, ^, <<, >>, ~. But, ~ uses its own function and does not call this version.

Overrides:

getLocalLearningObjectives in class Bitwise

evaluate

public Value evaluate()

Description copied from class: Bitwise

Evaluates a binary bitwise operator

Overrides:

evaluate in class Bitwise

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:
