# Repository Overview

Welcome! If you're reading this, you're about to dive into a Java-based codebase that models business data structures through three interrelated classes. This repository appears to implement a lightweight domain model — possibly for a workflow or processing system — where patterns are organized into hierarchical categories. Below you'll find everything you need to orient yourself quickly.

## Overview

This repository contains a small Java project composed of three classes. Based on the naming and field conventions (including Japanese comments), this appears to model business processing entities — likely supporting a service interface layer where processing categories, service identifiers, and classification codes are managed. The classes form a directed dependency graph suggesting that the `Mixed` class acts as a central entry point referencing the other two pattern classes.

## Technology Stack

This project is written in **Java** and appears to use a minimal dependency footprint — no well-known frameworks (such as Spring, Hibernate, or Jackson) were detected from import analysis. The codebase is kept deliberately lean, with plain POJOs (Plain Old Java Objects) and no detected external libraries.

## Architecture

The project follows a simple class-based structure with three top-level classes in the default package. The dependency graph shows `Mixed` as a central class that depends on both `PatternA` and `PatternB`, while `PatternA` in turn depends on `PatternB`, forming a directed chain.

    Root --> PatternB["PatternB"]
    Mixed --> PatternA
    Mixed --> PatternB
    PatternA --> PatternB
```

**Dependency relationships:**

- **Mixed** references both `PatternA` and `PatternB` — it appears to be the primary integration point or context class.
- **PatternA** references `PatternB` — suggesting a hierarchical or composed relationship where processing classification logic builds upon service identification logic.
- **PatternB** is a leaf class with no outgoing dependencies, containing the foundational service-level identifiers.

## Module Guide

Since this repository uses the default (unnamed) package rather than a multi-module structure, the "modules" here correspond to the three source classes, each serving a distinct role:

- **`Mixed`** — This class appears to serve as the central or aggregation class, combining fields from multiple patterns. It holds an `englishOnly` string (intended for English-language content) and an unlabeled field. It acts as the main entry point referencing both `PatternA` and `PatternB`.

- **`PatternA`** — This class defines a processing classification field (`syoriDiv`, translated from the comment as "processing category" or "processing division"). It depends on `PatternB`, suggesting that processing logic is built on top of service-level identifiers.

- **`PatternB`** — This class holds foundational identifiers: a `templateID` (service interface ID) and an `identifyCD` (identification code). As a leaf dependency, it provides the base data contract that both `PatternA` and `Mixed` build upon.

## Getting Started

If you're new to this codebase, here's a recommended reading order:

1. **Start with `PatternB.java`** — it's the smallest class and defines the foundational data contract (service interface ID and identification code). Understanding this gives you the base vocabulary.
2. **Read `PatternA.java` next** — it builds on `PatternB` and introduces the processing classification concept. This shows how the patterns compose.
3. **Then examine `Mixed.java`** — as the class that references both patterns, this gives you the full picture of how the pieces fit together at the application level.

All three classes are in the default package under `src/main/java/`, so there's no package-level nesting to navigate. The code is intentionally lightweight — each class contains only field declarations, making it straightforward to scan the full codebase in a single pass.

From here, you may want to explore the [Mixed](src\main\java\Mixed.java), [PatternA](src\main\java\PatternA.java), and [PatternB](src\main\java\PatternB.java) class reference pages for detailed field documentation.
