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.

Greeter constructor

Source

Welcomes a user through the configured logger. It implements IGreeter.

The logger dependency is injected as Logger and stored read-only (the application logger, injected when resolved).

Receive fields: injected logger. Explanation.

Greeter.greet

Source

Prints a personalized greeting.

It takes name as a string. It gets console (Console) from dependency injection.

It can call Console.write.
