Constructor Detail

AbstractLoopModel

public AbstractLoopModel(java.lang.String inTemplate)

public AbstractLoopModel(int startingIteration); This is the contstructor for the AbstractLoopModel. It will initialize the number of iterations present in the loop, as well as set all flags to false and all Strings to "";

Parameters:

startingIteration - - the number of times the loop has iterated

Method Detail

getPossibleErrors

public java.lang.String[] getPossibleErrors()

Method to return errors for variables May want to post-process based on Student Model

Overrides:

getPossibleErrors in class ConditionControl

getLoopValues

public void getLoopValues(java.util.Vector condVarVector,
                          java.util.Vector condValueVector)

public void getLoopValues(Vector condVarVector, Vector condValueVector) This function determines whether or not a condition has left/right hand sides or not. If so, it places the value from the lhs into condVarVector and the rhs value int condValueVector. If there are no sides, we take the value of the statement and place in both vectors

Parameters:

condVarVector - - a vector holding the left hand side Value object

condValueVector - - a vector holding the right hand side Value object

main

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