/**
|
|
* @fileoverview `CascadingConfigArrayFactory` class.
|
|
*
|
|
* `CascadingConfigArrayFactory` class has a responsibility:
|
|
*
|
|
* 1. Handles cascading of config files.
|
|
*
|
|
* It provides two methods:
|
|
*
|
|
* - `getConfigArrayForFile(filePath)`
|
|
* Get the corresponded configuration of a given file. This method doesn't
|
|
* throw even if the given file didn't exist.
|
|
* - `clearCache()`
|
|
* Clear the internal cache. You have to call this method when
|
|
* `additionalPluginPool` was updated if `baseConfig` or `cliConfig` depends
|
|
* on the additional plugins. (`CLIEngine#addPlugin()` method calls this.)
