# Business Logic — FUW02301SFLogic.getDispInfo() [197 LOC]

| Field | Value |
|-------|-------|
| Fully Qualified Name | `eo.web.webview.FUW02301SF.FUW02301SFLogic` |

| Module | `FUW02301SF` (Package: `eo.web.webview.FUW02301SF`) |

## 1. Role

### FUW02301SFLogic.getDispInfo()

This method prepares the display-ready information for the **eoWEB Mail self-service settings screen** (FUW02301SF), which allows customers to manage their optional E-Mail service settings. It reads the current customer's optional service contract data, resolves the matching E-Mail service record by POP ID, and computes display values for five configuration areas: **mail alias subscription status**, **settings inheritance status**, **old email forwarding status**, **mail virus check service status**, and **mail password field**. The method implements a **routing/dispatch pattern**: it iterates through optional service contract records to find the one whose POP ID matches the current user's SSO POP ID and whose service code is `B001` (E-Mail), then branches its output based on inbound flags (`MSKM_SETTE_HKTG` and `MSKM_OLD_MAIL_TENSO`) that indicate whether the customer selected "inherit settings" or "forward from old email." This method serves as the **display data transformer** called from both the screen initialization flow (`cfm()`) and the confirmation flow (`mskm()`), ensuring the customer sees consistent, pre-computed values regardless of the entry point.

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `commoninfoBean` | `X31SDataBeanAccess` | Shared form bean carrying the current session's context, including the WEB change information structure. It serves as the top-level container for navigating into nested data trees: WEB Change Info → SSO Info → Current Customer Info → Service Contract Info → Service Contract Details Info → Optional Service Contract Info array. This bean originates from the shared form mechanism and represents the customer's identity and service context for the current page request. |
| 2 | `bean` | `X31SDataBeanAccess` | Output data bean to which the method writes all display values. The method populates this bean's fields with computed results: mailbox capacity (MB or GB), mail alias (actual alias or status message), settings inheritance display text, old mail forwarding display text, mail virus check service status, and mail password placeholder. This bean is the contract output returned to the caller for rendering on the web screen. |

**Instance fields / external state read:**

| Name | Type | Description |
|------|------|-------------|
| `GIGA_BYTE` | `String` | Private constant `"GB"` — unit suffix for gigabyte display |
| `MEGA_BYTE` | `String` | Private constant `"MB"` — unit suffix for megabyte display |
| `KEIYAKU_CHYU` | `String` | Private constant `"契約中"` (Under contract) — display text when mail virus check is active |
| `GORIYOU_NASHI` | `String` | Private constant `"ご利用なし"` (Not in use) — display text when a service is not active |
| `HIKITUGANAI` | `String` | Private constant `"引き継がない"` (Do not inherit) — display text for settings inheritance rejection |
| `MWKML_SETTE_HIKITUGU` | `String` | Private constant `"eoWEBメールで設定されていた場合は引き継ぐ"` (Inherit if set in eoWEB Mail) — display text for settings inheritance acceptance |
| `MWKML_SETTE_HIKITUGANAI` | `String` | Private constant `"eoWEBメールで設定されていても引き継がない"` (Do not inherit even if set in eoWEB Mail) — display text for settings inheritance rejection in the non-inheritance branch |
| `TENSOU_SURU` | `String` | Private constant `"転送する"` (Forward) — display text when forwarding from old email is selected |
| `TENSOU_SHINAI` | `String` | Private constant `"転送しない"` (Do not forward) — display text when forwarding from old email is not selected |
| `ML_PWD_MONGON` | `String` | Private constant `"変更前ののお申し込み内容を引継ぐ"` (Inherit pre-change order details) — placeholder for the mail password field |
| `BIGDECMAL1024` | `BigDecimal` | Constant value `1024` — threshold used to decide whether mailbox capacity should be displayed in GB or MB |

## 4. CRUD Operations / Called Services

### Pre-computed evidence from code analysis graph:

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |
|------|----------|---------|-------------|----------------------|
| R | `CommonInfoCFConst` field access | — | — | Reads nested data bean structures via `getDataBeanArray()` and `getDataBean()` on `commoninfoBean` to extract WEB Change Information, SSO Information, Current Customer Information, Service Contract Information, Service Contract Details Information, and Optional Service Contract Information. No database hit — these are in-memory data bean traversals. |
| R | `sendMessageString` (parameter reads) | — | — | Reads POP ID, optional service code, mailbox capacity, optional service contract numbers, sub-operation service codes, sub-operation service contract status, alias values, and display flags from data bean objects using `sendMessageString(value, X31CWebConst.DATABEAN_GET_VALUE)`. |
| R | `sendMessageBoolean` (parameter reads) | — | — | Reads boolean flags `MSKM_SETTE_HKTG` (Settings Inheritance) and `MSKM_OLD_MAIL_TENSO` (Old Email Forwarding) from the input bean. These flags come from the customer's screen selection. |
| R | `OneStopDataBeanAccessArray.getCount()` | OneStopDataBeanAccessArray | — | Iterates over optional service contract information array entries to find the matching E-Mail service record. |
| R | `OneStopDataBeanAccessArray.getDataBean(int)` | OneStopDataBeanAccessArray | — | Retrieves individual array elements by index during the optional service contract and sub-operation service contract iteration loops. |
| R | `OneStopDataBeanAccess.getDataBeanArray(String)` | OneStopDataBeanAccess | — | Navigates nested data bean hierarchies (e.g., extracting Optional Service Contract Information array from Service Contract Details Information). |
| - | `sendMessageString` (output writes) | — | — | Writes computed display values to the output bean: mailbox capacity, mail alias, settings inheritance text, old mail forwarding text, mail virus check status, and mail password placeholder. |
| - | `sendMessageString` (POP ID reads) | — | — | Reads POP ID from SSO info and from each optional service contract entry. Used for matching the current customer's E-Mail service record. |

**Note:** This method performs **no direct database operations**. All data is retrieved from in-memory data bean structures (`X31SDataBeanAccess` / `X31SDataBeanAccessArray`) that were populated earlier in the request lifecycle by other screen components. The method acts as a **display transformer**, not a data accessor.

## 5. Dependency Trace

| # | Caller (Screen/Batch) | Call Chain (Full Path to this Method) | Terminal (SC / CRUD / Entity) |
|---|----------------------|--------------------------------------|-------------------------------|
| 1 | Method: `FUW02301SFLogic.cfm()` | `cfm()` → `getDispInfo(commoninfoBean, bean)` | `sendMessageString` [-] (writes to output bean) |
| 2 | Method: `FUW02301SFLogic.mskm()` | `mskm()` → `getDispInfo(commoninfoBean, bean)` | `sendMessageString` [-] (writes to output bean) |

**Terminal operations from `getDispInfo`:** The method exclusively writes display values via `sendMessageString()` calls on the output `bean` parameter. It does not invoke any SC (Service Component) or CBS (Composite Business Service) methods, and does not reach any database tables. The terminal operations are all in-memory bean writes.
