| /** |
| * @fileoverview The factory of `ConfigArray` objects. |
| * |
| * This class provides methods to create `ConfigArray` instance. |
| * |
| * - `create(configData, options)` |
| * Create a `ConfigArray` instance from a config data. This is to handle CLI |
| * options except `--config`. |
| * - `loadFile(filePath, options)` |
| * Create a `ConfigArray` instance from a config file. This is to handle |
| * `--config` option. If the file was not found, throws the following error: |
| * - If the filename was `*.js`, a `MODULE_NOT_FOUND` error. |
| * - If the filename was `package.json`, an IO error or an |
| * `ESLINT_CONFIG_FIELD_NOT_FOUND` error. |
| * - Otherwise, an IO error such as `ENOENT`. |
| * - `loadInDirectory(directoryPath, options)` |
| * Create a `ConfigArray` instance from a config file which is on a given |
| * directory. This tries to load `.eslintrc.*` or `package.json`. If not |
| * found, returns an empty `ConfigArray`. |
| * - `loadESLintIgnore(filePath)` |
| * Create a `ConfigArray` instance from a config file that is `.eslintignore` |
| * format. This is to handle `--ignore-path` option. |
| * - `loadDefaultESLintIgnore()` |
| * Create a `ConfigArray` instance from `.eslintignore` or `package.json` in |
| * the current working directory. |
| * |
| * `ConfigArrayFactory` class has the responsibility that loads configuration |
| * files, including loading `extends`, `parser`, and `plugins`. The created |
| * `ConfigArray` instance has the loaded `extends`, `parser`, and `plugins`. |
| * |
| * But this class doesn't handle cascading. `CascadingConfigArrayFactory` class |
| * handles cascading and hierarchy. |
