*
|
* - `toCompatibleObjectAsConfigFileContent()`
|
* Convert this configuration to the compatible object as the content of
|
* config files. It converts the loaded parser and plugins to strings.
|
* `CLIEngine#getConfigForFile(filePath)` method uses this method.
|
*
|
* `ConfigArray#extractConfig(filePath)` creates a `ExtractedConfig` instance.
