Description copied from class: TeacherAnswerValue

Determines whether a student's response matches this answer value.

A matching response does not imply the given response is correct.

Your subclass can implement this method by calling the default method #isMatchDefault(StudentResponseValue).

The semantics of your problem type might prevent your AnswerValue subclass from calling the isMatchDefault(StudentResponseValue) method.

One case is when the problem type does not implement a 1:1 matching of answer value parts to response value parts.

For example: A range problem is not going to match the student's response (with a single value part) to the answer value parts (which represent a lower- and upper-limit). Rather the range problem must provide an isMatch() implementation that checks if the student's response, a single-part answer value, falls between the two limits.

Specified by:

isMatch in class TeacherAnswerValue<PlusMinusRangeAnswerValuePart,PlusMinusRangeResponseValue>

Parameters:

response - The response to compare to this answer value.

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

Returns:

true if response matches this answer value; otherwise false
