## 1. Role

### KKW22101SF03DBean.loadModelData()

This method is a **data-type routing dispatcher** for the "EO Smart Link" (EOスマートリンク) view-screen data model. It receives a business-level item name (`key`) and a data-type accessor (`subkey`), then routes the request to the appropriate getter method on this bean. It implements the **routing/dispatch pattern** (a form of the Mediator pattern at the view layer) to provide a uniform interface for reading structured data from a dynamically-typed view bean hierarchy. This is the X33 framework's `loadModelData` contract implementation — it is the primary entry point that the framework calls when any screen component needs to resolve a typed data property (value, enabled state, or UI state) by its human-readable label.

The method handles **8 distinct data types**, each representing a different aspect of an EO Smart Link contract item: machine provision service contract number, model number, pro-rated billing month, terminal purchase method, settlement total amount, settlement monthly amount, settlement remaining month, and pro-rated sales form code. For each data type, three accessors are supported via the `subkey` parameter: `value` (returns the actual data), `enable` (returns the UI enabled/disabled flag), and `state` (returns the UI state, e.g., displayed/hidden). If no matching key or subkey is found, the method returns `null`, indicating the request is not recognized.

**Block classification:** This method implements a **double-dispatch routing** pattern. The first dispatch level matches the `key` string against one of 8 data type labels (case-sensitive). The second dispatch level matches the `subkey` string (`"value"`, `"enable"`, `"state"` — case-insensitive) against three accessor prefixes. This two-level routing enables a uniform typed-data interface used by the X33V framework's dynamic view bean system.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `key` | `String` | The business item label identifying which EO Smart Link data type to access. Represents one of 8 contract item categories displayed on the EO Smart Link details list screen. Values include "EO Smart Link - Machine Provision Service Contract Number" (item ID: `smtlnk_kktk_svc_kei_no`), "EO Smart Link - Model" (`smtlnk_kiki_model`), "EO Smart Link - Pro-rated Billing Month" (`smtlnk_kap_kisan_ym`), "EO Smart Link - Terminal Purchase Method" (`smtlnk_tnmt_buy_way`), "EO Smart Link - Settlement Total Amount" (`smtlnk_ssn_kin_all_amnt`), "EO Smart Link - Settlement Monthly Amount" (`smtlnk_ssn_kin_gtgk`), "EO Smart Link - Settlement Remaining Month" (`smtlnk_ssn_kin_zan_getu`), or "EO Smart Link - Pro-rated Sales Form Code" (`smtlnk_kap_hambai_form_cd`). Case-sensitive match. |
| 2 | `subkey` | `String` | The data accessor type indicating which property of the selected item to return. Accepts `"value"` (the actual data value), `"enable"` (whether the UI element is enabled/disabled), or `"state"` (the UI state, e.g., displayed or hidden). Case-insensitive comparison via `equalsIgnoreCase`. |

**Instance fields read by this method:**

The method delegates to 24 getter methods that each read one of 24 protected instance fields. These fields represent the three accessors (value, enabled, state) for each of the 8 data types:

This method performs **pure read operations** — it contains no Create, Update, or Delete operations. It does not call any SC (Service Component) or CBS (Common Business Service) methods, nor does it access any database tables directly. All 24 calls are to simple getter methods that return instance field values. The data itself was previously populated by other screen processing methods (not part of this method). The `indexOf('/')` call on line 363 serves only to parse the key string for potential nesting but its return value is unused in this method.

## 5. Dependency Trace

This method is invoked by the X33V framework's dynamic data binding system. The framework resolves item data by calling `loadModelData(key, subkey)` on list bean components (e.g., `X33VDataTypeList` items) during screen initialization and data display.

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Screen:KKSV22101 (inferred) | `KKW22101SFBean.getSmtlnk_info_list_list` -> `X33VDataTypeList` item -> `KKW22101SF03DBean.loadModelData(key, subkey)` | `getSmtlnk_*_value/state/enable [R] instance fields` |

The call chain:
1. `KKW22101SFBean` (parent screen bean) constructs `smtlnk_info_list_list` as an `X33VDataTypeList` where each item is instantiated as a `KKW22101SF03DBean` (see KKW22101SFBean.java ~L4268: `KKW22101SF03DBean tmpBean = new KKW22101SF03DBean();`)
2. The X33V framework calls `loadModelData("EO Smart Link - <data type>", "value"/"enable"/"state")` on each list item to retrieve typed data for rendering
3. The `KKW22101SFBean.loadModelData()` method also delegates to this bean's implementation when the key matches "EO Smart Link Details List" (EOスマートリンク明細一覧リスト)
