# Getting Started

This repository is a very small Java codebase with three example classes and no visible framework wiring. It looks like a compact reference set for comparing field declaration styles, comment conventions, and simple mapping patterns rather than a production application.

## What This Project Does

The project demonstrates a few ways to document and structure fields in Java classes. `PatternA` shows a block-annotated field, `PatternB` shows a small field mapping table, and `Mixed` shows a plain class with minimal annotation. If you are onboarding, your goal is to understand these examples and how they relate to the code documentation generated under `.codewiki`.

## Recommended Reading Order

1. [`.codewiki/overview.md`](../overview.md) — start here for the high-level summary of the repository.
2. [`src/main/java/PatternA.java`](../../src/main/java/PatternA.java) — read this first to see the simplest annotated pattern.
3. [`src/main/java/PatternB.java`](../../src/main/java/PatternB.java) — next, compare the mapping-table style.
4. [`src/main/java/Mixed.java`](../../src/main/java/Mixed.java) — finish with the plain example to see the least annotated form.

## Key Entry Points

There are no highly referenced classes in this repository, so the main entry points are the three Java files themselves:

- [`PatternA.java`](../../src/main/java/PatternA.java) — a single field wrapped in start/end comment markers.
- [`PatternB.java`](../../src/main/java/PatternB.java) — a small `FIELD_MAP` constant that pairs field names with types.
- [`Mixed.java`](../../src/main/java/Mixed.java) — a minimal class with one labeled field and one unlabeled field.

## Project Structure

The source tree is flat and intentionally small:

- `.codewiki/` — generated documentation for the repo.
- `src/main/java/` — the only source directory currently present.
- `PatternA.java`, `PatternB.java`, `Mixed.java` — standalone example classes with no visible inheritance or dependency chain.

A simple mental model is:

Root["Repository"] --> Docs[".codewiki"]
Root --> Source["src/main/java"]
Source --> PatternA["PatternA.java"]
Source --> PatternB["PatternB.java"]
Source --> Mixed["Mixed.java"]
```

## Configuration

No build tool, application config, or environment-specific settings are visible in the indexed files. At the moment, the only meaningful configuration-like material is the documentation metadata under `.codewiki/`:

- [`.codewiki/overview.md`](../overview.md) — repository summary and navigation aid.
- [`.codewiki/tree.json`](../tree.json) — generated structure information used by the wiki.

If additional build files exist later, document them here first; right now there is nothing else to configure.

## Common Patterns

A few patterns repeat across the codebase:

- **Very small classes:** each Java file contains a single public class with a tiny surface area.
- **Inline field documentation:** comments are used to describe fields, often in Japanese.
- **Constant-based mapping:** `PatternB` stores name/type pairs in a `String[][]` constant.
- **Minimal abstraction:** there are no services, frameworks, or complex dependencies to learn first.

## Where to Go Next

After you understand the three source files, browse the rest of the `.codewiki` pages for generated context. If you need to change code, start by matching the existing comment and field-style patterns so new code stays consistent with the current examples.
