/**

* This file was auto generated on Apr 5, 2020 and can be modified and extended upon
|
||||
*
|
||||
* Base repository methods are automatically
|
||||
* generated in the "base" version of this repository. The base repository
|
||||
* is immutable and to be left untouched, while methods in this class
|
||||
* are used as extension methods for more specific persistence-layer
|
||||
* accessors or mutators
|
||||
*
|
||||
* Base Methods (Subject to be expanded upon in time)
|
||||
*
|
||||
* InsertOne
|
||||
* UpdateOne
|
||||
* DeleteOne
|
||||
* FindOne
|
||||
* GetWhere(std::string where_filter)
|
||||
* DeleteWhere(std::string where_filter)
|
||||
* InsertMany
|
||||
* All
|
||||
*
|
||||
* Example custom methods in a repository
|
||||
*
|
||||
* BuyerRepository::GetByZoneAndVersion(int zone_id, int zone_version)
|
||||
* BuyerRepository::GetWhereNeverExpires()
|
||||
* BuyerRepository::GetWhereXAndY()
|
||||
* BuyerRepository::DeleteWhereXAndY()
|
||||
*
|
||||
* Most of the above could be covered by base methods, but if you as a developer
|
||||
* find yourself re-using logic for other parts of the code, its best to just make a
|
||||
* method that can be re-used easily elsewhere especially if it can use a base repository
|
||||
* method and encapsulate filters there
