LSLStreamInfo.fromStreamInfo constructor

LSLStreamInfo.fromStreamInfo(lsl_streaminfo streamInfo)

Creates a new LSLStreamInfo object from an existing lsl_streaminfo.

When constructing inlets, this creates the LSLStreamInfo object based on an existing lsl_streaminfo object, which can be retrieved from a stream resolver.

Implementation

factory LSLStreamInfo.fromStreamInfo(lsl_streaminfo streamInfo) {
  final Pointer<Utf8> streamName = lsl_get_name(streamInfo) as Pointer<Utf8>;
  final Pointer<Utf8> streamType = lsl_get_type(streamInfo) as Pointer<Utf8>;
  final int channelCount = lsl_get_channel_count(streamInfo);
  final double sampleRate = lsl_get_nominal_srate(streamInfo);
  final lsl_channel_format_t channelFormat = lsl_get_channel_format(
    streamInfo,
  );
  final Pointer<Utf8> sourceId =
      lsl_get_source_id(streamInfo) as Pointer<Utf8>;
  final String streamTypeString = streamType.toDartString();
  final info = LSLStreamInfo(
    streamName: streamName.toDartString(),
    streamType: LSLContentType.values.firstWhere(
      (e) => e.value == streamTypeString,
      orElse: () => LSLContentType.custom(
        streamTypeString,
      ), // Default to custom if not found
    ),
    channelCount: channelCount,
    sampleRate: sampleRate,
    channelFormat: LSLChannelFormat.values.firstWhere(
      (e) => e.lslFormat == channelFormat,
      orElse: () =>
          LSLChannelFormat.float32, // Default to float32 if not found
    ),
    sourceId: sourceId.toDartString(),
    streamInfo: streamInfo,
