Constructor & Destructor Documentation

__construct()

assAnswerCloze::__construct	(		$answertext = "",
			$points = 0.0,
			$order = 0
	)

assAnswerCloze constructor

The constructor takes possible arguments an creates an instance of the assAnswerCloze object.

Parameters

string	$answertext	A string defining the answer text
double	$points	The number of points given for the selected answer
integer	$order	A nonnegative value representing a possible display or sort order

Returns

assAnswerCloze See if the initialization of the bounds to null can be avoided to have them string/numeric at all times.
