  An exception class used for signaling run-time failure of reading and writing operations.

  In addition to a message string, a reference to another `Throwable` (`Error` or `Exception`) is maintained. This reference, if non-`null`, refers to the event that caused this exception to occur. For example, an `IOException` while reading from a `File` would be stored there.
