Method: FoodAbstract#initialize

Defined in:
lib/food/food_class.rb

#initialize(name, protein_energy_pair, glucid_energy_pair, lipid_energy_pair) ⇒ FoodAbstract

Constructor of Abstract Food for allowing the childs to call it.

Parameters:

  • name (String) —

    the name for the food.

  • protein_energy_pair (pair) —

    pair of protein number and energy.

  • glucid_energy_pair (pair) —

    pair of glucid number and energy

  • lipid_energy_pair (pair) —

    pair of lipid number and energy

  • lipid_energy_pair (pair) —

    pair of lipid number and energy
