RAII: Initializing data member in const method
- by Thomas Matthews
In RAII, resources are not initialized until they are accessed. However, many access methods are declared constant. I need to call a mutable (non-const) function to initialize a data member.
Example: Loading from a data base
struct MyClass
{
int get_value(void) const;
private:
void load_from_database(void); // Loads the data member…
