Defined in:
lib/glassfrog/utils/graph.rb

Overview

Encapsulates utilities for building a circle hierarchy based on supporting roles/supported circles.

Class Method Details

.hierarchy(client, circles = nil, roles = nil) ⇒ Glassfrog::Circle

Populates each circle’s sub_circles array with its respective sub circles. This done by finding all of the supporting roles and the circle to which they belong.

      (parent_circle.sub_circles ? parent_circle.sub_circles.push(sub_circle) : parent_circle.sub_circles = [sub_circle]) if parent_circle
  end
  root(circles, roles)
end

.root(circles, roles) ⇒ Glassfrog::Circle

Finds the root of the ‘circle tree’ by finding the role that does not belong to a circle.
