state property

LineScannerState state
override

The scanner's state, including line and column information.

This can be used to efficiently save and restore the state of the scanner when backtracking. A given LineScannerState is only valid for the LineScanner that created it.

This does not include the scanner's match information.

Implementation 

LineScannerState get state => new _SpanScannerState(this, position);
void state= (LineScannerState state)
override

Implementation 

set state(LineScannerState state) {
  if (state is! _SpanScannerState ||
      !identical((state as _SpanScannerState)._scanner, this)) {
    throw new ArgumentError("The given LineScannerState was not returned by "
        "this LineScanner.");
  }

  this.position = state.position;
}
