Overview

Selections on an object may apply differently depending on what is actually returned by the resolve function. Find the maximum possible complexity among those combinations.

  max = 0
  @types.each_value do |fields|
    complexity = fields.each_value.inject(:+)
    max = complexity if complexity > max
  end
  max
end

#merge(type_defn, key, complexity) ⇒ Object

Store the complexity for the branch on type_defn. Later we will see if this is the max complexity among branches.
