  org.problets.domain.model.expression.node.NodeView
      org.problets.domain.model.expression.node.student.StudentNodeView
          org.problets.domain.model.expression.node.student.ParenthesizedStudentNodeView

All Implemented Interfaces:

java.lang.Cloneable

public class ParenthesizedStudentNodeView
extends StudentNodeView

To hold intermediate node in the student's evaluation tree that is a parenthesized subexpression - expect that the operatorsCovered will contain the parenthesis and the root of the enclosed sub-expression.

Constructor Detail

ParenthesizedStudentNodeView

public ParenthesizedStudentNodeView(ParenthesisView inOperator)

This constructor is called by BailedOutStudentNodeView when constructing the right hand side expression short circuited by the student. As such, it will use the leftX and rightX values of the original operator, since the StudentNodeView is synthetically constructed rather than specified by the student drawing an underbrace. The operator being passed as a parameter is the root of the expression embedded within the parenthesis.

ParenthesizedStudentNodeView

public ParenthesizedStudentNodeView(NodeView inOperator,
                                    java.util.Vector inOperandsCovered,
                                    int inLeftX,
                                    int inRightX,
                                    int inOrder)

This constructor is called by StudentNodeView when Parenthesis.isSeparateStep

Method Detail

setCenter

public void setCenter(NodeView inCenter)

Called by ParenthesisView.getCopyIfExists() when constructing the subexpression what the student "bailed over" in Logical.BAILOUT mode

isResultLocallyCorrect

public boolean isResultLocallyCorrect()

Called by ExpressionProblemView ONLY when Parenthesis.isSeparateStep. Returns true if the value of the parenthesized expression is the same as the only operand enclosed by the parenthesis and false otherwise

Overrides:

isResultLocallyCorrect in class StudentNodeView

main

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