const { MetadataStorage } = require('../../lib/metadata');
const { Collection, ReferenceType } = require('../../lib');

/**
 * @property {number} id

      if ([ReferenceType.ONE_TO_MANY, ReferenceType.MANY_TO_MANY].includes(props[prop].reference)) {
        this[prop] = new Collection(this);
      }
    });
  }

}

const schema = {

      primary: true,
      type: 'number',
