Member Function Documentation

canUseAdvancedRating()

assFormulaQuestionGUI::canUseAdvancedRating (   $result )

Check if advanced rating can be used for a result.

This is only possible if there is exactly one possible correct unit for the result, otherwise it is impossible to determine wheather the unit is correct or the value.

Returns

boolean True if advanced rating could be used, false otherwise
