Constructor Detail

PlusMinusRangeProblem

public PlusMinusRangeProblem(java.lang.String uid)

Constructor For use when calling code directly needs an instance of ProblemFillIn.

Parameters:

uid - UID of this instance.

PlusMinusRangeProblem

protected PlusMinusRangeProblem(java.lang.String classType,
                                java.lang.String uid)

Constructor For use when ProblemFillIn has been subclassed. In that case the subclass will need to use this constructor to specify its classType.

Parameters:

classType - Subclass' class type as a fully specified name. For example: org.assistments.core.domain.FillInWithUnitsProblem.

uid -

Method Detail

getProblemAttributes

public static AnswerableProblemAttributes getProblemAttributes()

Returns the problem type attributes for PlusMinusRangeProblem.

This is a convenience method so that a caller can gain access to the problem type attributes without having to first instantiate an instance of PlusMinusRangeProblem.

See Also:

AnswerableProblem.getProblemTypeAttributes(), AnswerableProblem.getProblemTypeAttributes(String)

getClassName

public static java.lang.String getClassName()

Returns this class' fully specified name.

addAnswer

public PlusMinusRangeAnswer addAnswer(java.lang.String uid,
                                      boolean isCorrect,
                                      AnswerEvalType expectedValueEvalType,
                                      java.lang.String expectedValue,
                                      AnswerEvalType plusMinusEvalType,
                                      java.lang.String plusMinusValue)

addAnswer

public PlusMinusRangeAnswer addAnswer(java.lang.String uid,
                                      boolean isCorrect,
                                      PlusMinusRangeAnswerValuePart... valueParts)

Description copied from class: AnswerableProblem

Given a list of value parts, returns a subclass instance of an Answer containing those values.

It is highly recommended that each AnswerableProblem subclass implements a custom, public version of the addAnswer(...) method which hides from the calling code the variable arguments AnswerValuePart... valueParts.

For example, a fill in problem would implement:

public FillInAnswer addAnswer(String uid, boolean isCorrect, String value)

The implementation of this abstract method would be responsible for obtaining the evaluation type, and the subsequent creation of an AnswerValuePart.

Specified by:

addAnswer in class AnswerableProblem<PlusMinusRangeAnswerValuePart,PlusMinusRangeAnswer,PlusMinusRangeAnswerValue,PlusMinusRangeResponseValue>

Parameters:

uid - Unique identifier for this answer

valueParts - The value parts comprising this answer.

Returns:

For informational purposes, the newly create Answer

See Also:

AnswerableProblem.getAnswerEvalTypes(), AnswerValuePart

makeResponse

public PlusMinusRangeResponseValue makeResponse(java.lang.String studentResponse)

Creates and returns a student response value.

Parameters:

studentResponse - The fill-in value entered by a student.

makeResponse

protected PlusMinusRangeResponseValue makeResponse(java.lang.String... responseParts)

Description copied from class: AnswerableProblem

For the given values entered, returns an AnswerValue containing those parts.

Specified by:

makeResponse in class AnswerableProblem<PlusMinusRangeAnswerValuePart,PlusMinusRangeAnswer,PlusMinusRangeAnswerValue,PlusMinusRangeResponseValue>

Parameters:

responseParts - One or more values entered in response to a question. For example, a fill-in problem expects a single response string. An ordered pair problem expects two response strings.

Returns:

A subclass of AnswerValue. By convention the subclass should be named: <problem name>StudentResponseValue

isCorrect

public boolean isCorrect(PlusMinusRangeResponseValue response,
                         java.util.Map<java.lang.String,java.lang.String> args)

Description copied from class: AnswerableProblem

Determines whether the submitted response to this question is correct.

If your problem type defines correctness as when the student's response matches any one of the answers marked as a correct answer, then your subclass can implement this method to call #isCorrectDefault(StudentResponseValue).

If your problem type requires a different semantic for determining correctness, you must implement that logic yourself in isCorrect(). In this case, your implementation may want (or need) to call AnswerableProblem.setWrongAnswer(Answer) so that a common wrong answer is available later to a caller.

Specified by:

isCorrect in class AnswerableProblem<PlusMinusRangeAnswerValuePart,PlusMinusRangeAnswer,PlusMinusRangeAnswerValue,PlusMinusRangeResponseValue>

Parameters:

response - The student's response to compare to this problem's answer list.

args - Map for problem specific properties that will be used in calculating correctness for the problem.

Returns:

true if the response matches one of the correct answers; otherwise false
