Methods

map<TResult extends Object?>({required TResult getItem(ReadOperation<T> value), required TResult getItems(ReadListOperation<T> value), required TResult getByIds(ReadByIdsOperation<T> value), required TResult setItem(WriteOperation<T> value), required TResult setItems(WriteListOperation<T> value), required TResult delete(DeleteOperation<T> value)}) → TResult

Available on Operation<T>, provided by the OperationPatterns extension

A switch-like method, using callbacks.

mapOrNull<TResult extends Object?>({TResult? getItem(ReadOperation<T> value)?, TResult? getItems(ReadListOperation<T> value)?, TResult? getByIds(ReadByIdsOperation<T> value)?, TResult? setItem(WriteOperation<T> value)?, TResult? setItems(WriteListOperation<T> value)?, TResult? delete(DeleteOperation<T> value)?}) → TResult?

Available on Operation<T>, provided by the OperationPatterns extension

A variant of map that fallback to returning null.

maybeMap<TResult extends Object?>({TResult getItem(ReadOperation<T> value)?, TResult getItems(ReadListOperation<T> value)?, TResult getByIds(ReadByIdsOperation<T> value)?, TResult setItem(WriteOperation<T> value)?, TResult setItems(WriteListOperation<T> value)?, TResult delete(DeleteOperation<T> value)?, required TResult orElse()}) → TResult

Available on Operation<T>, provided by the OperationPatterns extension

A variant of map that fallback to returning orElse.

maybeWhen<TResult extends Object?>({TResult getItem(String operationId, String itemId, RequestDetails details, DateTime createdAt, int attemptNumber)?, TResult getItems(String operationId, RequestDetails details, DateTime createdAt, int attemptNumber)?, TResult getByIds(String operationId, Set<String> itemIds, RequestDetails details, DateTime createdAt, int attemptNumber)?, TResult setItem(String operationId, RequestDetails details, T item, DateTime createdAt, int attemptNumber)?, TResult setItems(String operationId, RequestDetails details, Iterable<T> items, DateTime createdAt, int attemptNumber)?, TResult delete(String operationId, String itemId, RequestDetails details, DateTime createdAt, int attemptNumber)?, required TResult orElse()}) → TResult

Available on Operation<T>, provided by the OperationPatterns extension

A variant of when that fallback to an orElse callback.

when<TResult extends Object?>({required TResult getItem(String operationId, String itemId, RequestDetails details, DateTime createdAt, int attemptNumber), required TResult getItems(String operationId, RequestDetails details, DateTime createdAt, int attemptNumber), required TResult getByIds(String operationId, Set<String> itemIds, RequestDetails details, DateTime createdAt, int attemptNumber), required TResult setItem(String operationId, RequestDetails details, T item, DateTime createdAt, int attemptNumber), required TResult setItems(String operationId, RequestDetails details, Iterable<T> items, DateTime createdAt, int attemptNumber), required TResult delete(String operationId, String itemId, RequestDetails details, DateTime createdAt, int attemptNumber)}) → TResult
