# startChunkedConversion method

StringConversionSink startChunkedConversion (Sink<List<int>> sink)

Starts a chunked conversion.

The converter works more efficiently if the given `sink` is a ByteConversionSink.

## Implementation

    StringConversionSink startChunkedConversion(Sink<List<int>> sink) {
      if (sink is! ByteConversionSink) {
        sink = new ByteConversionSink.from(sink);
      }
      return new _UnicodeSubsetEncoderSink(_subsetMask, sink);
    }
