/**
 * A timeout stream is triggered by a timer, the {@link io.vertx.core.Handler} will be call when the timer is fired,
 * it can be once or several times depending on the nature of the timer related to this stream. The
 * {@link ReadStream#endHandler(Handler)} will be called after the timer handler has been called.
 * <p>
 * Pausing the timer inhibits the timer shots until the stream is resumed. Setting a null handler callback cancels
 * the timer.
