Member Function Documentation

◆ __toString()

question_state::__toString ( )

inherited

Return values

string convert this state to a string.

◆ corresponding_commented_state()

question_state::corresponding_commented_state ( $fraction )

inherited

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

Parameters

number $fraction the manual grade (if any) on the fraction scale.

Return values

int	the new state.

Reimplemented in question_state_finished, question_state_gaveup, question_state_graded, and question_state_needsgrading.

◆ default_string()

question_state::default_string ( $showcorrectness )

inherited

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

Parameters

bool $showcorrectness Whether right/partial/wrong states should be distinguised.

Return values

string a string from the lang pack that can be used in the UI.

◆ get()

static question_state::get ( string $name )

staticinherited

Get the instance of this class for a given state name.

Parameters

string $name a state name.

Return values

question_state|null the state with that name. (Null only in an exceptional case.)

◆ get_all()

static question_state::get_all ( )

staticinherited

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 )

staticinherited

Get all the states in an array.

Parameters

string $summarystate one of the four summary states inprogress, needsgrading, manuallygraded or autograded.

Return values

array of the corresponding states.

◆ get_feedback_class()

question_state::get_feedback_class ( )

inherited

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

Return values

string

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

◆ get_state_class()

question_state_notstarted::get_state_class ( $showcorrectness )

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 $showcorrectness Whether right/partial/wrong states should be distinguised, or just treated as 'complete'.

Return values

string the name of a string that can be looked up in the 'question' lang pack, or used as a CSS class name, etc.

Reimplemented from question_state.

◆ get_summary_state()

question_state::get_summary_state ( )

inherited

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

Return values

string which category this state falls into.

◆ graded_state_for_fraction()

static question_state::graded_state_for_fraction ( $fraction )

staticinherited

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 $fraction the grade, on the fraction scale.

Return values

question_state one of the state constants.

◆ is_active()

question_state::is_active ( )

inherited

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_complete, question_state_invalid, and question_state_todo.

◆ 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 ( )

inherited

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.

static question_state::manually_graded_state_for_fraction ( $fraction )

staticinherited

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 $fraction the grade, on the fraction scale.

Return values

int	one of the state constants.
