CASE ANALYSIS

Scenario

A software team needs to document the object-oriented design of a topological sort library that supports multiple graph traversal strategies and detects cycles in directed graphs.

Key decisions

  • Modeled the sorting strategy as an interface with Kahn's and DFS as interchangeable implementations
  • Composed Graph from Vertex and DirectedEdge with multiplicity to enforce graph invariants
  • Included CycleDetector as a dependency for algorithms that need cycle validation

When to reuse this

Use this diagram when designing or documenting graph algorithm libraries, educational materials on topological sorting, or dependency resolution systems that operate on directed acyclic graphs.
