ORM Interfaces
Maybe it's will base for my custom js-orm, maybe not:), but I think it's a helpful interfaces let see them:
NullObject<T> It's has few simple methods for works with DTO or Entity object, for example:
- isExists - check its empty object or not
- isChanged - check, are you changed original object or not
- isSaved - check, are you saved changed or new object or not
- getDiff - get difference between original object and current his state
- setProperties - it's method for initialization NullObject, you'll can set you properties there
- toSimpleObject - get original object without NullObject abstraction
Selectable<T>It's simple interface for select by search condition (S) and return NullObject or NullObject collection, its has one method
- find - by criteria and optional params - order
Writable<T>It's simple interface for write to your storage with methods:
- bulkUpdate
- bulkSave
- bulkDelete
- save
- delete
And, for comfort ORM interface - combine Selectable and Writable
