# Com / Example

## Overview

The `com.example` package serves as the root namespace for example and test code within this project. It does not contain production-facing components. Instead, it hosts minimal fixture classes used to validate tooling behavior — most notably, Java import resolution and language feature handling.

This appears to be a test harness area. Classes here are intentionally thin (no fields, no-op methods) so that consuming code can verify that the build tools, IDE support, or compiler correctly resolve imports across modules.

## Sub-module Guide

The `com.example` package currently contains one child sub-module:

### `bugca002` — Import Resolution Fixture

This sub-module (`com.example.bugca002`) provides a single class, `KnownClass`, whose sole purpose is to act as a resolvable import target. It is referenced by other modules (notably JSP views in the `BugCa002Language` module) to confirm that import resolution and language tooling work correctly.

The naming convention (`bugca002`) suggests it was created as a regression test fixture tied to a specific bug tracking ID. The class and its `execute()` method are intentionally minimal — no state, no side effects — so the test measures tooling behavior rather than application behavior.

**How it relates to other modules:** This sub-module is a leaf dependency. Other code depends on it for validation; it does not depend on anything else in the project. This unidirectional dependency is by design — the fixture must remain self-contained so that import resolution can be tested in isolation.

## Key Patterns and Architecture

The `com.example` package follows a single pattern: **fixture-first design**.

- **Minimal classes.** Every class has no fields and methods with empty bodies. The only meaningful behavior is structural (existence and accessibility).
- **Test-driven naming.** Package names like `bugca002` map to specific bug test case IDs, making it easy for developers to locate the fixture relevant to a given regression test.
- **Cross-module validation.** The value of these classes is realized only when imported and resolved by code in other modules. The sub-modules are designed to be consumed, not to stand alone.

This diagram shows how the `bugca002` fixture is consumed: a JSP view in another module imports `KnownClass` from `com.example.bugca002`, and may call its `execute()` method to verify full resolution (both class-level and method-level).

## Dependencies and Integration

- **Outbound dependencies:** None. No class in `com.example` imports or references code outside `java.lang`.
- **Inbound dependencies:** The `BugCa002Language` module (specifically its JSP views) imports `KnownClass` from this package.
- **Integration role:** This package is a leaf node in the dependency graph. It provides a stable, dependency-free target for import resolution tests without pulling in external libraries or creating circular dependency risk.

## Notes for Developers

- **Do not treat as production code.** Classes in this package are fixtures with intentionally empty implementations. They exist to exercise tooling, not to implement business logic.
- **Adding new fixtures.** When a new test case needs an import target, follow the existing convention: create a package under `com.example.bugcaXXX` with a class containing a public, resolvable method. Keep it minimal — no fields, no side effects.
- **Tooling relevance.** If you are working on import resolution, language support, IDE features, or compiler diagnostics, this is the package to use as a test fixture. References to it can help verify that changes do not break cross-module symbol resolution.
