Class: qtype_multianswer_question - X-Ref
Represents a multianswer question.A multi-answer question is made of of several subquestions of various types.
You can think of it as an application of the composite pattern to qusetion
types.

| combine_states($overallstate, $newstate) X-Ref |
| Used by grade_response to combine the states of the subquestions. The combined state is accumulates in $overallstate. That will be right if all the separate states are right; and wrong if all the separate states are wrong, otherwise, it will be partially right. param: question_state $overallstate the result so far. param: question_state $newstate the new state to add to the combination. return: question_state the new combined state. |
