Member Function Documentation

◆ CreateAnother()

Question* mitk::Forms::ShortAnswerQuestion::CreateAnother ( ) const
overridevirtual

Create a new instance of the derived question class type.

This method is mainly used by IQuestionFactory to create new instances from registered prototype instances based on a type string.

Question* RhetoricalQuestion::CreateAnother() const
{
return new RhetoricalQuestion;
}

GetType()

Implements mitk::Forms::Question.

◆ FromJSON()

void mitk::Forms::ShortAnswerQuestion::FromJSON ( const nlohmann::ordered_json &  j)
overridevirtual

Deserialize from JSON.

Polymorphism and the use of base class pointers make it necessary to implement serialization through member functions. Using the pure native approach of the "JSON for Modern C++" library via free functions would lead to partially serialized instances of derived classes.

The actual implementation can and should still be located in a corresponding from_json() free function but we also need the indirection through this member function.

void RhetoricalQuestion::FromJSON(const nlohmann::ordered_json& j)
{
from_json(j, *this);
}
See also
from_json(const nlohmann::ordered_json& j, Question& q)

Implements mitk::Forms::Question.

◆ GetType()

std::string mitk::Forms::ShortAnswerQuestion::GetType ( ) const
overridevirtual

Return the type of a question as string, e.g. "Multiple choice" or "Drop-down".

This method is essential for the deserialization of questions into their correct type, resp. derived class. The type string is used by IQuestionFactory to look up a registered prototype instance of a certain type to create another instance of it.

The type string does not have to match the class name or follow any other convention except for it must be unique amongst all question types. Prefer natural language like in the examples above in case it is used in a user interface to display a question's type.

std::string RhetoricalQuestion::GetType() const
{
return "Rhetorical";
}

CreateAnother()

Implements mitk::Forms::Question.

◆ ToJSON()

void mitk::Forms::ShortAnswerQuestion::ToJSON ( nlohmann::ordered_json &  j) const
overridevirtual

Serialize to JSON.

Polymorphism and the use of base class pointers make it necessary to implement serialization through member functions. Using the pure native approach of the "JSON for Modern C++" library via free functions would lead to partially serialized instances of derived classes.

The actual implementation can and should still be located in a corresponding to_json() free function but we also need the indirection through this member function.

void RhetoricalQuestion::ToJSON(nlohmann::ordered_json& j) const
{
to_json(j, *this);
}

Implements mitk::Forms::Question.
