# Getting Started

## What This Project Does
This repository is a very small Java codebase that appears to document or demonstrate field-declaration patterns rather than implement a full application. The main value is in understanding how the sample classes express labels, comments, and mapping metadata.

## Recommended Reading Order
1. [Overview](../overview.md) — start here for the high-level context.
2. [PatternA](../../src/main/java/PatternA.java) — learn the marker-based field pattern.
3. [PatternB](../../src/main/java/PatternB.java) — learn the mapping-table pattern.
4. [Mixed](../../src/main/java/Mixed.java) — compare the simpler mixed field style.

## Key Entry Points
The repository does not expose highly connected classes, so the best entry points are the three sample classes themselves:

- [PatternA](../../src/main/java/PatternA.java) — shows a field wrapped in explicit add markers.
- [PatternB](../../src/main/java/PatternB.java) — shows a `FIELD_MAP` table that pairs field names with types and comments.
- [Mixed](../../src/main/java/Mixed.java) — shows a minimal class with both labeled and unlabeled fields.

## Project Structure
The indexed source is concentrated in a single top-level area:

- `.codewiki/` — generated documentation for the repository
- `src/main/java/` — the Java examples
  - [Mixed.java](../../src/main/java/Mixed.java)
  - [PatternA.java](../../src/main/java/PatternA.java)
  - [PatternB.java](../../src/main/java/PatternB.java)

There are no visible controllers, services, or framework-specific packages in the current source set.

## Configuration
No application configuration files were detected in the indexed files. There is no visible build, runtime, or environment configuration to tune yet, so new engineers should first confirm whether additional modules or hidden build files exist outside the indexed sample set.

## Common Patterns
A few conventions repeat across the code:

- Small, single-purpose Java classes with no inheritance or interfaces.
- Field definitions are the main point of interest.
- Comments are used to carry metadata or labels, sometimes in Japanese.
- One class uses explicit add markers, while another uses a static field map.
- The code is simple and declarative, suggesting it may be consumed by tooling or used as a template/reference.

## Where to Start
If you just joined the team, read the files in this order:

1. [Overview](../overview.md)
2. [PatternA](../../src/main/java/PatternA.java)
3. [PatternB](../../src/main/java/PatternB.java)
4. [Mixed](../../src/main/java/Mixed.java)

That sequence gives you the repository intent first, then the two main patterns, then the contrast case.
