class Configuration
# Define a class instance variable (acts as our static property).
# This variable belongs directly to the Configuration class object,
# not to any instance of the class.
@environment = "production"
# Class method to safely read the static property (acting as a static getter)
def self.environment
@environment
end
# Class method to safely modify the static property with validation (acting as a static setter)
def self.environment=(new_env)
if new_env.is_a?(String) && !new_env.strip.empty?
@environment = new_env
end
end
# A class method that utilizes the static property
def self.get_environment_details()
"Active environment status: #{@environment}"
end
end
# --- Example Usage ---
# 1. Accessing the static property/method directly via the Class Name (Best Practice)
puts "Current Environment: #{Configuration.environment}"
puts Configuration.get_environment_details()
# 2. Modifying the static property using the class setter method
Configuration.environment = "staging"
puts "Updated Environment: #{Configuration.environment}"
# Note on Instances:
# config_instance = Configuration.new
# config_instance.environment # Raises a NoMethodError!
# Instances cannot access class-level static properties directly.
# run:
#
# Current Environment: production
# Active environment status: production
# Updated Environment: staging
