CASE ANALYSIS
Scenario
A software team needs to design an object-oriented implementation of Dijkstra's shortest path algorithm, clarifying responsibilities of graph storage, node/edge representation, and result computation.
Key decisions
- Model Graph as an interface with an abstract base class and AdjacencyListGraph concrete implementation
- Encapsulate shortest path results in a dedicated ShortestPathResult class holding distances and predecessors
- Represent nodes and edges as explicit classes, with edge associations to source and target nodes
When to reuse this
Use this diagram when designing graph algorithm libraries, pathfinding engines, or teaching object-oriented structure of graph traversal algorithms.
