Hey fellow code architects! Ever felt like your system is carrying unnecessary baggage? The Flyweight Design Pattern is like having a squadron of code butterflies – it minimizes memory usage and improves performance by sharing as much as possible. It's the ultimate lightweight champion for your code, ensuring your system can flutter through tasks with the grace of a butterfly!

Concept:

• Flyweight: Your code butterfly, representing a shared object that can be used in multiple contexts.
• FlyweightFactory: The butterfly breeder, managing and creating flyweights.
• Client: You, the maestro orchestrating this coding ballet.

Ruby Butterfly Ballet:

Let's twirl into a Ruby adventure that's as graceful as a ballet and as efficient as a well-choreographed dance.

Flyweight:

# Your code butterfly - the Flyweight
class CodeButterfly
  attr_reader :color

  def initialize(color)
    @color = color
  end

  def dance
    puts "Fluttering in a graceful dance, painted in #{@color}..."
  end
end

FlyweightFactory:

# The butterfly breeder - the FlyweightFactory
class ButterflyFactory
  def initialize
    @butterflies = {}
  end

  def get_butterfly(color)
    @butterflies[color] ||= CodeButterfly.new(color)
  end

  def total_butterflies
    @butterflies.size
  end
end

Butterfly Ballet Code:

# The maestro's ballet
butterfly_factory = ButterflyFactory.new

# Dancers enter the stage
blue_butterfly = butterfly_factory.get_butterfly('blue')
red_butterfly = butterfly_factory.get_butterfly('red')
green_butterfly = butterfly_factory.get_butterfly('green')

# Let the dance begin!
blue_butterfly.dance
red_butterfly.dance
green_butterfly.dance

# Adding a new dancer
yellow_butterfly = butterfly_factory.get_butterfly('yellow')
yellow_butterfly.dance

# Checking the butterfly count
puts "Total butterflies in the ballet: #{butterfly_factory.total_butterflies}"

Why It's a Butterfly Ballet:

The Flyweight Design Pattern is like choreographing a ballet with code butterflies. It minimizes memory usage by sharing common elements, making your system dance through tasks with feather-light efficiency. So, whether you're orchestrating a coding ballet or just want your code to flutter gracefully, the Flyweight Pattern is your dance instructor. Twirl on, code architects, twirl on! 🦋✨
