Class "Gap"

Abstract class Gap is not meant to be instantiated directly; instead, it serves as a base for derived classes such as NumericGap, TextGap, TextGapOpal and InlineChoice.

Slots

response_identifier

A character value representing an identifier for the answer. By default, it is generated as 'id_gap_dddd', where dddd represents random digits.

points

A numeric value, optional, representing the number of points for this gap. Default is 1.

incorrect

Score for an incorrect nonempty response, in points. Default 0. Numeric/text gaps allow a finite non-positive score; omitted or whitespace-only text responses receive zero.

expected_length

A numeric value, optional, used to set the size of the text input field in the content delivery engine.
