void	explain(java.util.Vector explanation) Graphically explains the evaluation of the expression as opposed to textual explanation by the model
int	getContentWidth()
NodeView	getCopyIfExists(java.util.Vector availableViews, java.lang.String presumedValue) If actualNodeView exists in availableViews, return a copy of it, else return null actualNodeView is part of the actual answer, an OperatorView or OperandView object.

OperatorView

public OperatorView(NodeModel inOperator)

Method Detail

getContentWidth

public int getContentWidth()

Overrides:

getContentWidth in class NodeView

getCopyIfExists

public NodeView getCopyIfExists(java.util.Vector availableViews,
                                java.lang.String presumedValue)

If actualNodeView exists in availableViews, return a copy of it, else return null actualNodeView is part of the actual answer, an OperatorView or OperandView object. availableViews consists of OperandViews and StudentNodeViews/BailedOutStudentNodeViews. Short-circuits any newly constructed operator nodes

Overrides:

getCopyIfExists in class NodeView

explain

public void explain(java.util.Vector explanation)

Graphically explains the evaluation of the expression as opposed to textual explanation by the model

Overrides:

explain in class NodeView
