/**
|
|
* @fileoverview `ConfigArray` class.
|
|
*
|
|
* `ConfigArray` class expresses the full of a configuration. It has the entry
|
|
* config file, base config files that were extended, loaded parsers, and loaded
|
|
* plugins.
|
|
*
|
|
* `ConfigArray` class provides three properties and two methods.
|
|
*
|
|
* - `pluginEnvironments`
|
|
* - `pluginProcessors`
|
|
* - `pluginRules`
|
|
* The `Map` objects that contain the members of all plugins that this
|
|
* config array contains. Those map objects don't have mutation methods.
|
|
* Those keys are the member ID such as `pluginId/memberName`.
|
|
* - `isRoot()`
|
|
* If `true` then this configuration has `root:true` property.
|
|
* - `extractConfig(filePath)`
|
|
* Extract the final configuration for a given file. This means merging
|
|
* every config array element which that `criteria` property matched. The
|
|
* `filePath` argument must be an absolute path.
|
|
*
|
|
* `ConfigArrayFactory` provides the loading logic of config files.
