encodeTextInteraction method

Uint8List encodeTextInteraction(RitoTextInteractionRequest request)

Encodes a RITOTIQ1 text interaction request.

Implementation

Uint8List encodeTextInteraction(RitoTextInteractionRequest request) {
  final writer = _Writer.message(ascii.encode('RITOTIQ1'), 1);
  writer.externalId(request.sessionId, 'session id');
  writer.externalId(request.artifactId, 'artifact id');
  switch (request.query) {
    case RitoCaretQuery(:final point):
      writer.uint8(0);
      _textPoint(writer, point);
    case RitoRangeQuery(:final anchor, :final focus):
      writer.uint8(1);
      _caretAddress(writer, anchor);
      _caretAddress(writer, focus);
    case RitoRangeToPointQuery(:final anchor, :final focus):
      writer.uint8(2);
      _caretAddress(writer, anchor);
      _textPoint(writer, focus);
    case RitoRangeFromPointsQuery(
      :final anchor,
      :final focus,
      :final granularity,
    ):
      writer.uint8(3);
      _textPoint(writer, anchor);
