$private Modifier on Class Members

∟$private Modifier on Class Members

This section describes the $private modifier on class members (variables and functions).

If you want to stop everyone accessing a class member (a variable or a function) from outside the class definition body, you can use the $private modifier to declare it to be privately accessible only.

Examples of using $private modifier on class members:

$class circle: {

   $private pi = 3.14159;

   $public $function area(radius): {
      return ^.pi*radius**2; 
   };

   $public $function circumference(radius): {
      return ^.pi*radius*2; 
   }
}

write(circle.pi); # gets NullPointer Error

write(circle.area(2.0)); 
write(circle.circumference(2.0));
