runZoned<R> method

R runZoned <R>(R body(), { Directory createDirectory(String), Directory getCurrentDirectory(), void setCurrentDirectory(String), Directory getSystemTempDirectory(), File createFile(String), Future<FileStat> stat(String), FileStat statSync(String), Future<bool> fseIdentical(String, String), bool fseIdenticalSync(String, String), Future<FileSystemEntityType> fseGetType(String, bool), FileSystemEntityType fseGetTypeSync(String, bool), Stream<FileSystemEvent> fsWatch(String, int, bool), bool fsWatchIsSupported(), Link createLink(String), Future<Socket> socketConnect(dynamic, int, { dynamic sourceAddress, Duration timeout }), Future<ConnectionTask<Socket>> socketStartConnect(dynamic, int, { dynamic sourceAddress }), ZoneSpecification zoneSpecification, Function onError })

Runs body in a fresh Zone using the provided overrides.

See the documentation on the corresponding methods of IOOverrides for information about what the optional arguments do.
