resolveByProperty method

Future<List<LSLStreamInfo>> resolveByProperty({ required LSLStreamProperty property, required String value, double waitTime = 5.0, int minStreamCount = 0, })

Resolves streams by a specific property. The property parameter is the property to filter by, such as name, type, channel count, etc. The value parameter is the value to filter by. The waitTime parameter determines how long to wait for streams to resolve, if the value is 0, the default of forever will be used, and will only return when the minStreamCount is met. The minStreamCount parameter is the minimum number of streams to resolve, it must be greater than 0. Returns a list of LSLStreamInfo objects that match the filter. Throws an LSLException if the resolver is not created or if there is an error resolving streams. You may get less streams than the minStreamCount if there are not enough streams available AND you have set a waitTime > 0.

Implementation

Future<List<LSLStreamInfo>> resolveByProperty({
  required LSLStreamProperty property,
  required String value,
  double waitTime = 5.0,
  int minStreamCount = 0,
}) async {
  if (!created) {
    throw LSLException('Resolver not created');
  }

  final streamCount = lsl_resolve_byprop(
    _streamInfoBuffer!,
    maxStreams,
    property.lslName.toNativeUtf8(allocator: allocate).cast<Char>(),
    value.toNativeUtf8(allocator: allocate).cast<Char>(),
    minStreamCount,
    waitTime,
  );
  if (streamCount < 0) {
    throw LSLException('Error resolving streams by property: $streamCount');
  }

  final streams = <LSLStreamInfo>[];
  for (var i = 0; i < streamCount; i++) {
    final streamInfo = LSLStreamInfo.fromStreamInfo(_streamInfoBuffer![i]);
    streams.add(streamInfo);
  }
  return streams;
}
