Detailed Description

An enumeration representing the states a question can be in after a question_attempt_step.

There are also some useful methods for testing and manipulating states.

Member Function Documentation

◆ __toString()

question_state::__toString ( )
Return values
stringconvert this state to a string.

◆ corresponding_commented_state()

question_state::corresponding_commented_state (   $fraction)

Compute an appropriate state to move to after a manual comment has been added to this state.

Parameters
number$fractionthe manual grade (if any) on the fraction scale.
Return values
intthe new state.

Reimplemented in question_state_needsgrading, question_state_finished, question_state_gaveup, and question_state_graded.

◆ default_string()

question_state::default_string (   $showcorrectness)

The result of doing get_string on the result of get_state_class().

Parameters
bool$showcorrectnessWhether right/partial/wrong states should be distinguised.
Return values
stringa string from the lang pack that can be used in the UI.

◆ get()

static question_state::get (   $name)
static
Parameters
string$namea state name.
Return values
question_statethe state with that name.

◆ get_all()

static question_state::get_all ( )
static

Get all the states in an array.

Return values
question_state[]of question_state objects.

◆ get_all_for_summary_state()

static question_state::get_all_for_summary_state (   $summarystate)
static

Get all the states in an array.

Parameters
string$summarystateone of the four summary states inprogress, needsgrading, manuallygraded or autograded.
Return values
arrayof the corresponding states.

◆ get_feedback_class()

question_state::get_feedback_class ( )

Return an appropriate CSS class name ''/'correct'/'partiallycorrect'/'incorrect', for a state.

Return values
string

Reimplemented in question_state_gaveup, question_state_gradedwrong, question_state_gradedpartial, question_state_gradedright, question_state_mangrwrong, question_state_mangrpartial, and question_state_mangrright.

◆ get_state_class()

question_state::get_state_class (   $showcorrectness)
abstract

Return the name of an appropriate string to look up in the question language pack for a state.

This is used, for example, by question_behaviour::get_state_string(). However, behaviours sometimes change this default string for soemthing more specific.

Parameters
bool$showcorrectnessWhether right/partial/wrong states should be distinguised, or just treated as 'complete'.
Return values
stringthe name of a string that can be looked up in the 'question' lang pack, or used as a CSS class name, etc.

Reimplemented in question_state_notstarted, question_state_unprocessed, question_state_todo, question_state_invalid, question_state_complete, question_state_needsgrading, question_state_finished, question_state_gaveup, and question_state_graded.

◆ get_summary_state()

question_state::get_summary_state ( )

Each state can be categorised into one of four categories: inprogress, needsgrading, manuallygraded or autograded.

Return values
stringwhich category this state falls into.

◆ graded_state_for_fraction()

static question_state::graded_state_for_fraction (   $fraction)
static

Return the appropriate graded state based on a fraction.

That is 0 or less is $graded_incorrect, 1 is $graded_correct, otherwise it is $graded_partcorrect. Appropriate allowance is made for rounding float values.

Parameters
number$fractionthe grade, on the fraction scale.
Return values
question_stateone of the state constants.

◆ is_active()

question_state::is_active ( )

Is this state one of the ones that mean the question attempt is in progress? That is, started, but no finished.

Return values
bool

Reimplemented in question_state_todo, question_state_invalid, and question_state_complete.

◆ is_commented()

question_state::is_commented ( )

Is this state one of the ones that mean the question attempt has had a manual comment added?

Return values
bool

Reimplemented in question_state_manfinished, question_state_mangaveup, and question_state_manuallygraded.

◆ is_correct()

question_state::is_correct ( )

Is this state one of the ones that mean the question attempt has been graded?

Return values
bool

Reimplemented in question_state_gradedright, and question_state_mangrright.

◆ is_finished()

question_state::is_finished ( )

Is this state one of the ones that mean the question attempt is finished? That is, no further interaction possible, apart from manual grading.

Return values
bool

Reimplemented in question_state_notstarted, question_state_unprocessed, question_state_todo, question_state_invalid, and question_state_complete.

◆ is_gave_up()

question_state::is_gave_up ( )

Is this state one of the ones that mean the question attempt has been graded?

Return values
bool

Reimplemented in question_state_gaveup.

◆ is_graded()

question_state::is_graded ( )

Is this state one of the ones that mean the question attempt has been graded?

Return values
bool

Reimplemented in question_state_graded, question_state_gradedpartial, and question_state_gradedright.

◆ is_incorrect()

question_state::is_incorrect ( )

Is this state one of the ones that mean the question attempt has been graded?

Return values
bool

Reimplemented in question_state_gradedwrong, and question_state_mangrwrong.

◆ is_partially_correct()

question_state::is_partially_correct ( )

Is this state one of the ones that mean the question attempt has been graded?

Return values
bool

Reimplemented in question_state_gradedpartial, and question_state_mangrpartial.

◆ manually_graded_state_for_fraction()

static question_state::manually_graded_state_for_fraction (   $fraction)
static

Return the appropriate manually graded state based on a fraction.

That is 0 or less is $manually_graded_incorrect, 1 is $manually_graded_correct, otherwise it is $manually_graded_partcorrect. Appropriate allowance is made for rounding float values.

Parameters
number$fractionthe grade, on the fraction scale.
Return values
intone of the state constants.
