+ * @fileoverview `FileEnumerator` class.
+ *
+ * `FileEnumerator` class has two responsibilities:
+ *
+ * 1. Find target files by processing glob patterns.
+ * 2. Tie each target file and appropriate configuration.
+ *
+ * It provides a method:
+ *
+ * - `iterateFiles(patterns)`
+ *     Iterate files which are matched by given patterns together with the
+ *     corresponded configuration. This is for `CLIEngine#executeOnFiles()`.
+ *     While iterating files, it loads the configuration file of each directory
+ *     before iterate files on the directory, so we can use the configuration
+ *     files to determine target files.
+ *
+ * @example
+ * const enumerator = new FileEnumerator();
+ * const linter = new Linter();
+ *
+ * for (const { config, filePath } of enumerator.iterateFiles(["*.js"])) {
+ *     const code = fs.readFileSync(filePath, "utf8");
+ *     const messages = linter.verify(code, config, filePath);
+ *
+ *     console.log(messages);
+ * }
