-/**
- * Basic input stream which supplies binary data.
- *
- * Input streams are used to read data sequentially from some data
- * source. All input streams are non-blocking. They each have a number
- * of read calls which will always return without any IO related
- * blocking. If the requested data is not available a read call will
- * return `null`. All input streams have one or more handlers which
- * will trigger when data is available.
- *
- * The following example shows a data handler in an ordinary input
- * stream which will be called when some data is available and a call
- * to read will not return `null`.
- *
- *     InputStream input = ...
- *     input.onData = () {
- *       var data = input.read();
- *       ...
- *     };
- *
- * If for some reason the data from an input stream cannot be handled
- * by the application immediately setting the data handler to `null`
- * will avoid further callbacks until it is set to a function
- * again. While the data handler is not active system flow control
- * will be used to avoid buffering more data than needed.
- *
- * Always set up appropriate handlers when using input streams.
- *
