ProxySource<T> class

Source whose constructor accepts a value for each operation type.

This is a build-a-source model to adapt an arbitrary data source to the pkg:data_layer system.

Constructors

ProxySource({required Bindings<T>? bindings, required SourceType sourceType, GetById<T>? getByIdHandler, GetByIds<T>? getByIdsHandler, GetItems<T>? getItemsHandler, SetItem<T>? setItemHandler, SetItems<T>? setItemsHandler, DeleteItem<T>? deleteHandler, DeleteItems<T>? deleteItemsHandler, SendMessage<T>? sendMessageHandler})

Source whose constructor accepts a value for each operation type.

Properties

bindings ↔ Bindings<T>

All meta information about T necessary to plug arbitrary data types into a Repository.

Methods

deleteItem(DeleteOperation<T> operation) → Future<DeleteResult<T>>

Clears an item with the given DeleteOperation.itemId if one exists.

override

deleteItems(DeleteListOperation<T> operation) → Future<DeleteResult<T>>

Clears all items matching the given DeleteListOperation.details.

override

getById(ReadOperation<T> operation) → Future<ReadResult<T>>

Loads the instance of T whose primary key is found at ReadOperation.itemId.

override

getByIds(ReadByIdsOperation<T> operation) → Future<ReadListResult<T>>
