Proxy Design Pattern: Code Bouncer for VIP Access

Hey code party planners! Ever wished your code could have a bouncer at the entrance, controlling access to the main event? The Proxy Design Pattern is like having a reliable bouncer – it acts as a placeholder, controlling access to an object. It's the ultimate VIP pass for your code, ensuring only the right guests get in. Let's explore this exclusive coding party together!

Concept:

• Subject: Your main event, the object you want to control access to.
• Proxy: The trusty bouncer, acting as a middleman between the client and the subject.
• RealSubject: The actual main event, accessible through the proxy.
• Client: You, the party planner, orchestrating this coding soirée.

Ruby Code Soirée:

Let's dive into a Ruby adventure that's as exclusive as a VIP party and as entertaining as a red carpet event.

Subject:

# Your main event - the Subject
class CodingParty
  def enter
    puts 'Everyone is welcome at the coding party!'
  end
end

Proxy:

# The trusty bouncer - the Proxy
class CodeBouncer
  def initialize(subject)
    @real_subject = subject
  end

  def enter
    check_access
    @real_subject.enter
  end

  private

  def check_access
    puts 'Bouncer checking VIP passes...'
    # Additional access control logic could go here
  end
end

Client:

# The party planner's script
coding_party = CodingParty.new
vip_party = CodeBouncer.new(coding_party)

# Let the coding soirée begin!
puts 'Regular Coding Party:'
coding_party.enter

puts "\nVIP Coding Party:"
vip_party.enter
