Sequences

Call arrows identify checked targets; loop and branch frames determine when they run. Open that target’s module to follow its implementation. Branches describe alternatives; loops describe repeated work. Native calls and interface dispatch stop at their declared contracts. Exit notes end that path; enclosing recovery and cleanup remain visible.

Repository.get

Source

It returns T.

Interface contract; implementation selected at runtime. Explanation.

NumberRepository constructor

Source

It implements Repository<int>.

Explanation.

NumberRepository.get

Source

Return 7; required cleanup runs before exit. Explanation.

Program constructor

Source

It implements IProgram.

The repository dependency is injected as Repository<int> and stored read-only.

Receive fields: injected repository. Explanation.

Program.start

Source

It gets console (Console) from dependency injection.

It can call Console.write.
