/**
|
|
* @fileoverview `ConfigDependency` class.
|
|
*
|
|
* `ConfigDependency` class expresses a loaded parser or plugin.
|
|
*
|
|
* If the parser or plugin was loaded successfully, it has `definition` property
|
|
* and `filePath` property. Otherwise, it has `error` property.
|
|
*
|
|
* When `JSON.stringify()` converted a `ConfigDependency` object to a JSON, it
|
|
* omits `definition` property.
|
|
*
|
|
* `ConfigArrayFactory` creates `ConfigDependency` objects when it loads parsers
|
|
* or plugins.
