* This file was auto generated 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)
|
|
*
|
|
* Note: Not all tables are designed appropriately to fit functionality with all base methods
|
|
*
|
|
* InsertOne
|
|
* UpdateOne
|
|
* DeleteOne
|
|
* FindOne
|
|
* GetWhere(std::string where_filter)
|
|
* DeleteWhere(std::string where_filter)
|
|
* InsertMany
|
|
* All
|
|
*
|
|
* Example custom methods in a repository
|
|
*
|
|
* ParcelsRepository::GetByZoneAndVersion(int zone_id, int zone_version)
|
|
* ParcelsRepository::GetWhereNeverExpires()
|
|
* ParcelsRepository::GetWhereXAndY()
|
|
* ParcelsRepository::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
