## 1. Role

### KKW03201SFLogic.searchList()

This method implements the **telephone number reservation list search and display** screen processing for the KKW03201SF module. It is the core entry point that retrieves a paginated list of telephone number reservation records (050-number / telephone number reservations) and prepares them for screen rendering. The method performs a **service dispatch pattern**: it gathers input data from the parameter DataBean, maps it via a DB mapper into an input map, invokes a backend service component (`KKSV010001SC`) through `invokeService`, then maps the output map back into the DataBean for display.

Within the larger system, this method represents a **read-heavy search workflow** — it does not create, update, or delete any database records. Instead, it queries an existing service for telephone number reservation data, applies pagination controls, populates error/success messages based on result count, and formats the result set for UI rendering (including alternating row stripe flags, default first-row selection, and display code-name resolution).

The method handles several conditional branches: page reset behavior (when called from paging vs. initial load), search result count thresholds (zero results, over maximum, no data flag), and the primary result loop (assigning row numbers, stripe display flags, and default first-item selection).

## 3. Parameter Analysis

| No | Parameter Name | Type | Business Description |
|----|---------------|------|---------------------|
| 1 | `paramBean` | `X31SDataBeanAccess[]` | Array of DataBean accessors carrying the search screen state. `paramBean[0]` holds both input parameters (search criteria, display settings) and output results (telephone number reservation list, display flags). Contains usage start date (year/month/day), telephone number reservation codes, and the result list array (`LIST_050_NO_INFO`). |
| 2 | `pageReset` | `boolean` | Controls whether pagination state should be reset. When `true`, the page link information is cleared via `clearPageLinkInfo`, typically triggered on initial screen load or when the user initiates a new search from scratch. When `false`, pagination context is preserved, typically during paging operations (`actionPaging`) or trigger-based re-searches (`actionTelnoHtb`). |

**Instance fields / external state read:**

| Source | Description |
|--------|-------------|
| `super.getCommonInfoBean()` | Retrieves the shared screen context bean that carries cross-screen navigation metadata (next screen ID, next screen name). |
| `super.getServiceFormBean()` | Accessed indirectly via `setClear()` to clear the service form bean's list array and telephone number display field. |
| `this` (instance reference) | Passed to `clearPageLinkInfo`, `upmapperPageLinkInfo`, `downmapperPageLinkInfo`, `setSearchCommand`, and `setMessageInfo` as the request scope context. |

## 4. CRUD Operations / Called Services

| CRUD | SC / CBS | SC Code | Entity / DB | Operation Description |

| R | `KKSV0100_KKSV0100OPDBMapper.getKKSV010001SC` | KKSV010001SC | - | Maps output results from outputMap back into paramBean for display rendering. |
| R | `JCCBatCommon.invokeService` | KKSV010001SC | - | Invokes the backend service component to execute the telephone number reservation search query. UCID=UCID_KKSV0100, OperationID=OPID_KKSV0100OP. |
| R | `JCCWebCommon.getSearchErrFlg` | KKSV010001SC | - | Retrieves the search error flag from the output map to determine result count status. |
| R | `JCCWebCommon.getSearchConst` | - | - | Retrieves system constants for max search count (`KKW03201_MAX_SHOW_CNT`) and rows per page (`KKW03201_ROW_PER_PAGE`). |
| - | `JCCWebCommon.clearPageLinkInfo` | - | - | Clears pagination link state when pageReset is true. |
| - | `JCCWebCommon.upmapperPageLinkInfo` | - | - | Maps pagination parameters from the request into the input map before service invocation. |
| - | `JCCWebCommon.downmapperPageLinkInfo` | - | - | Maps pagination results from the output map back after service invocation. |
| - | `JCCWebCommon.setSearchCommand` | - | - | Sets the search command context to "paging" for the calling screen. |
| - | `JCCWebCommon.setMessageInfo` | - | - | Sets user-facing error/success messages based on search result count. |
| C | `setClear` | - | - | Clears the telephone number reservation list array (`LIST_050_NO_INFO`) and the display field (`HRADSI_050_NO`) from the service form bean. |

**CRUD Summary:** This method is **Read-only** from a database perspective. It invokes a single read service component (`KKSV010001SC`) and performs no Create, Update, or Delete operations on persistent data. The `setClear()` helper only clears in-memory display state, not database records.
