Flyweight pattern

Here's a pseudocode example of a flyweight pattern. Try to match classes with their types.

class Shape is
  float size
  String line

  constructor of Shape(size, line) is ...



class Creator is
  List(Shape) shapes;

  method getShape(size, line) is
    shape = shapes.contains(size, line)
    if(shape == null)
       shape = new Shape(size, line)
       shapes.add(shape)
    return shape



class Circle is
  String circle
  Shape circleShape

  constructor of Circle(round, circleShape) is ...
