Detailed Description

Representing the analysis of each of the sub parts of each variant of the question.

• There is a separate data structure for each question or sub question's analysis core_question::statistics::responses::analysis_for_question or core_question::statistics::responses::analysis_for_question_all_tries.
• There are separate analysis for each variant in this top level instance.
• Then there are class instances representing the analysis of each of the sub parts of each variant of the question. core_question::statistics::responses::analysis_for_subpart.
• Then within the sub part analysis there are response class analysis core_question::statistics::responses::analysis_for_class.
• Then within each class analysis there are analysis for each actual response core_question::statistics::responses::analysis_for_actual_response.

__construct()

core_question\statistics\responses\analysis_for_subpart::__construct

(

array

$responseclasses

as returned from question_type::get_possible_responses().

Member Function Documentation

cache()

core_question\statistics\responses\analysis_for_subpart::cache	(		$qubaids,
			$whichtries,
			$questionid,
			$variantno,
			$subpartid,
			$calculationtime = null )

Cache analysis for sub part.

Parameters

qubaid_condition	$qubaids	which question usages have been analysed.
string	$whichtries	which tries have been analysed?
int	$questionid	which question.
int	$variantno	which variant.
string	$subpartid	which sub part.
int | null	$calculationtime	time when the analysis was done. (Defaults to time()).

count_response()

core_question\statistics\responses\analysis_for_subpart::count_response	(		$subpart,
			$try = 0 )

Count a part of a response.

Parameters

question_classified_response	$subpart
int	$try	the try number or zero if not keeping track of try number

get_maximum_tries()

core_question\statistics\responses\analysis_for_subpart::get_maximum_tries

(

Return values

int

max tries

get_response_class()

core_question\statistics\responses\analysis_for_subpart::get_response_class

(

$classid

)
