Implementation

@override
Future open(String? correlationId) async {
  if (references != null) {
    var err = InvalidStateException(
        correlationId, 'ALREADY_OPENED', 'Container was already opened');
    throw err;
  }

  try {
    logger.trace(correlationId, 'Starting container.');

    // Create references with configured components
    references = ContainerReferences([]);
    _initReferences(references!);
    if (config != null) references!.putFromConfig(config!);
    setReferences(references!);

    // Get custom description if available
    var infoDescriptor = Descriptor('*', 'context-info', '*', '*', '*');
    info = references!.getOneOptional<ContextInfo>(infoDescriptor);
    try {
      await references!.open(correlationId);

      // Get reference to logger
      logger = CompositeLogger(references);
      logger.info(correlationId, 'Container %s started.', [info?.name]);
      return null;
    } catch (err) {
      logger.fatal(
          correlationId, err as Exception, 'Failed to start container');
      await close(correlationId);
    }
  } catch (ex) {
    logger.fatal(correlationId, ex as Exception, 'Failed to start container');

    await close(correlationId);
  }
