getCapabilities method

@override Future<CapabilitySnapshot> getCapabilities()

Reports, for every QueryDomain, which operations (read / write / observe / stream) are usable on this device right now. Check this before issuing any request — the unsupported default reports everything as false.

Implementation

@override
Future<CapabilitySnapshot> getCapabilities() async {
  getCapabilitiesCalls += 1;
  return _capabilities;
}
