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_state_class()

question_state_invalid::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.

Return values

string

which category this state falls into.
