 /**
  * 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.dataHandler = () {
+ *    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.
