# Getting Started

## What This Project Does
This repository is a small Java codebase made up of simple domain-style classes and lightweight service/processor examples. There is no obvious framework layer here; most files are plain POJOs, field maps, or tiny methods that demonstrate naming and labeling conventions. If you're new to the team, your goal is to understand the handful of behavior classes first, then skim the data-holder classes that illustrate the project’s field patterns.

## Recommended Reading Order
1. [Overview](../overview.md) — start here for the high-level shape of the repository.
2. [root](../root.md) — this is the only module in the current code map.
3. Read the behavior classes next:
   - [OrderProcessor](../../src/main/java/OrderProcessor.java)
   - [ProductService](../../src/main/java/ProductService.java)
4. Then skim the label-heavy data classes to learn the naming conventions:
   - [LargeFieldMap](../../src/main/java/LargeFieldMap.java)
   - [EucJpClass](../../src/main/java/EucJpClass.java)
   - [MixedLabelClass](../../src/main/java/MixedLabelClass.java)
   - [PartialLabelEntity](../../src/main/java/PartialLabelEntity.java)
   - [MultiPattern](../../src/main/java/MultiPattern.java)
   - [LargeBusinessLabelClass](../../src/main/java/LargeBusinessLabelClass.java)
5. Finish with the placeholder class [A](../../src/main/java/A.java) if you want the full file list.

## Key Entry Points
The codebase does not currently expose highly connected classes, so the best entry points are the small behavior classes:

- [OrderProcessor](../../src/main/java/OrderProcessor.java) — the clearest documented behavior; it includes a `createOrder` method and Javadoc.
- [ProductService](../../src/main/java/ProductService.java) — a minimal service-style class with a simple getter.

After those, the other classes are best understood as examples of field naming and comment labeling patterns rather than as active logic.

## Project Structure
The repository is flat and easy to scan:

- `.codewiki/` — generated documentation and repository map files.
- `src/main/java/` — all visible Java source files in this snapshot.
  - Behavior examples: `OrderProcessor`, `ProductService`
  - Field-label examples: `LargeFieldMap`, `EucJpClass`, `MixedLabelClass`, `PartialLabelEntity`, `MultiPattern`, `LargeBusinessLabelClass`
  - Placeholder: `A`

There are no nested packages shown in the available index, so most of the learning value comes from reading the classes directly.

## Configuration
No build or runtime configuration files were surfaced in the indexed repository snapshot. That usually means one of two things:

- this is a very small sample or test repository, or
- the code generation index only captured source files and not the surrounding build files.

If you need to extend the project, first check for standard Java build files such as `pom.xml`, `build.gradle`, or `settings.gradle` in the repo root. In the current snapshot, the main configuration signal is the source itself: Javadoc, inline comments, and naming conventions.

## Common Patterns
A few conventions show up repeatedly across the source files:

- **Plain Java classes** — no framework annotations or dependency injection patterns are visible.
- **String-backed fields** — most classes are simple containers for string data.
- **Inline field comments** — many properties carry Japanese labels or short descriptive comments.
- **Minimal methods** — the behavior classes return or echo values directly, which keeps examples easy to understand.
- **Naming pattern examples** — several files appear to exist specifically to demonstrate different comment and label styles (`mixed`, `partial`, `multi-pattern`, and large field maps).

## Where To Go Next
If you are onboarding, read [OrderProcessor](../../src/main/java/OrderProcessor.java) and [ProductService](../../src/main/java/ProductService.java) first, then skim the field-heavy classes to learn how the team represents business terms in code comments. After that, you should be able to navigate the repository confidently and recognize whether a new file is meant to hold behavior or simply model data.
