+/**
+ * HasteMap is a JavaScript implementation of Facebook's haste module system.
+ *
+ * This implementation is inspired by https://github.com/facebook/node-haste
+ * and was built with for high-performance in large code repositories with
+ * hundreds of thousands of files. This implementation is scalable and provides
+ * predictable performance.
+ *
+ * Because the haste map creation and synchronization is critical to startup
+ * performance and most tasks are blocked by I/O this class makes heavy use of
+ * synchronous operations. It uses worker processes for parallelizing file
+ * access and metadata extraction.
+ *
+ * The data structures created by `jest-haste-map` can be used directly from the
+ * cache without further processing. The metadata objects in the `files` and
+ * `map` objects contain cross-references: a metadata object from one can look
+ * up the corresponding metadata object in the other map. Note that in most
+ * projects, the number of files will be greater than the number of haste
+ * modules one module can refer to many files based on platform extensions.
+ *
+ * type HasteMap = {
+ *   clocks: WatchmanClocks,
+ *   files: {[filepath: string]: FileMetaData},
+ *   map: {[id: string]: ModuleMapItem},
+ *   mocks: {[id: string]: string},
+ * }
+ *
+ * // Watchman clocks are used for query synchronization and file system deltas.
+ * type WatchmanClocks = {[filepath: string]: string};
+ *
+ * type FileMetaData = {
+ *   id: ?string, // used to look up module metadata objects in `map`.
+ *   mtime: number, // check for outdated files.
+ *   size: number, // size of the file in bytes.
+ *   visited: boolean, // whether the file has been parsed or not.
+ *   dependencies: Array<string>, // all relative dependencies of this file.
+ *   sha1: ?string, // SHA-1 of the file, if requested via options.
+ * };
+ *
+ * // Modules can be targeted to a specific platform based on the file name.
+ * // Example: platform.ios.js and Platform.android.js will both map to the same
+ * // `Platform` module. The platform should be specified during resolution.
+ * type ModuleMapItem = {[platform: string]: ModuleMetaData};
+ *
+ * //
+ * type ModuleMetaData = {
+ *   path: string, // the path to look up the file object in `files`.
+ *   type: string, // the module type (either `package` or `module`).
+ * };
+ *
+ * Note that the data structures described above are conceptual only. The actual
+ * implementation uses arrays and constant keys for metadata storage. Instead of
+ * `{id: 'flatMap', mtime: 3421, size: 42, visited: true, dependencies: []}` the real
+ * representation is similar to `['flatMap', 3421, 42, 1, []]` to save storage space
+ * and reduce parse and write time of a big JSON blob.
+ *
+ * The HasteMap is created as follows:
+ *  1. read data from the cache or create an empty structure.
+ *
+ *  2. crawl the file system.
+ *     * empty cache: crawl the entire file system.
+ *     * cache available:
+ *       * if watchman is available: get file system delta changes.
+ *       * if watchman is unavailable: crawl the entire file system.
+ *     * build metadata objects for every file. This builds the `files` part of
+ *       the `HasteMap`.
+ *
+ *  3. parse and extract metadata from changed files.
+ *     * this is done in parallel over worker processes to improve performance.
+ *     * the worst case is to parse all files.
+ *     * the best case is no file system access and retrieving all data from
+ *       the cache.
+ *     * the average case is a small number of changed files.
+ *
+ *  4. serialize the new `HasteMap` in a cache file.
+ *     Worker processes can directly access the cache through `HasteMap.read()`.
