moveCursor method

bool moveCursor(
  1. num dx,
  2. num dy, [
  3. void callback()
])

Moves this stream's cursor relative to its current position.

Returns false if the stream wishes for the calling code to wait for the 'drain' event to be emitted before continuing to write additional data; otherwise true.

Optional callback function is invoked once the operation completes.

Implementation

external bool moveCursor(num dx, num dy, [void Function() callback]);
