# Repository Overview

Welcome to this repository. This appears to be a very small Java codebase focused on a few example classes that demonstrate different field and comment patterns. It does not appear to use a major framework or application runtime, so the code is likely meant as a simple reference, sample, or test fixture. The main things to notice are the naming patterns, inline comments, and how fields are declared across the classes.

## Overview

This project appears to contain a minimal set of Java source files under a single root module. The classes `Mixed`, `PatternA`, and `PatternB` suggest the repository is demonstrating or comparing different code patterns rather than implementing a full business application. Because there are only a few files, a new reader should be able to understand the entire codebase quickly by starting with the class declarations and the comments inside each file.

## Technology Stack

- Java source files
- No well-known frameworks detected from import analysis
- Plain class definitions and constants/fields
- Comment annotations in both English and Japanese

## Architecture

This repository appears to have a flat structure with one root documentation module and three Java classes beneath it. There are no visible package-level dependencies, service layers, or external libraries in the indexed files, so the architecture is best understood as a small set of independent examples.

## Module Guide

### root

The `root` module appears to be the top-level documentation container for the repository. It does not define classes itself, but it provides the entry point for understanding the codebase and its structure. The three visible Java files seem to be the main contents worth reading first.

### Mixed

`Mixed.java` appears to define a simple `Mixed` class with two string fields: one clearly labeled `englishOnly` and one `unlabeled`. This file seems useful as a minimal example of field naming and inline commentary. If you are looking for the simplest class in the repository, this is probably the one to start with.

### PatternA

`PatternA.java` appears to show a class with a tagged comment block and a field named `syoriDiv`, which is annotated with a Japanese comment meaning “processing division.” The `ANK-0001 ADD START` and `ANK-0001 ADD END` markers suggest the file is demonstrating a specific modification pattern or code-generation convention. This class is likely important if you need to understand how the repository marks inserted or managed code sections.

### PatternB

`PatternB.java` appears to define a `FIELD_MAP` constant as a two-dimensional array of field-name/type pairs. The entries include `templateID` and `identifyCD`, each with a `String` type and Japanese comments describing their meaning. This class seems to demonstrate structured metadata mapping, possibly for field configuration or template-driven processing.

## Getting Started

A good reading order for a new developer is:

1. Start with `Mixed.java` to get a feel for the simplest class structure in the repository.
2. Read `PatternA.java` next to understand the tagged comment block pattern.
3. Finish with `PatternB.java` to see how field metadata is represented in a compact mapping table.
4. Review `.codewiki/root.md` for the higher-level documentation context.

If you are trying to understand the repository quickly, focus on the field declarations and comments rather than looking for framework setup or runtime wiring. This codebase appears small enough that the entire structure can be grasped from just these three source files.
