Overview

StatisticsCalculator provides comprehensive statistics about a UML repository

Calculates detailed metrics including:

  • Package statistics (depth distribution, sizes)

  • Class statistics (by stereotype, complexity)

  • Attribute statistics (type distribution, multiplicity)

  • Association statistics

  • Diagram statistics

  • Model quality metrics

Examples:

Getting repository statistics

calculator = StatisticsCalculator.new(document, indexes)
stats = calculator.calculate
puts "Total packages: #{stats[:total_packages]}"
puts "Most complex class: #{stats[:most_complex_classes].first[:name]}"
