lengthUntilZero method

int lengthUntilZero({
  1. int? maxLength,
})

Returns the number of bytes before the next zero byte.

If maxLength is null, throws RawReaderException if zero is not found. Otherwise returns `maxLength if zero is not found.

Implementation

int lengthUntilZero({int? maxLength}) {
  final byteData = this._byteData;
  final start = this.index;
  int end;
  if (maxLength == null) {
    end = _byteData.lengthInBytes;
  } else {
    end = start + maxLength;
  }
  for (var i = start; i < end; i++) {
    if (byteData.getUint8(i) == 0) {
      return i - start;
    }
  }
  if (maxLength != null) {
    return maxLength;
  }
  throw _eofException(start, "sequence of bytes terminated by zero");
}
