Classes
-
BaseCacheStrategy<P extends RequestParams, R>
-
A base implementation of a cache strategy that integrates a Cache
with a request/response stream mechanism.
-
BaseDataSource<P extends RequestParams, R>
-
Base implementation of the DataSource interface that integrates
with a CacheStrategy to manage fetching, caching, and streaming
of request states.
-
BaseExternalStreamDataSource<P extends RequestParams, R>
-
A base implementation of DataSource that integrates with an
external Stream of values instead of performing direct requests.
-
BaseKeyValueCache<R>
-
Base implementation of a key-value cache
that uses a KeyValueStoreInterface for persistence.
-
BaseRepo<P extends RequestParams, E>
-
A base implementation of the Repo interface.
-
Cache<R>
-
A generic cache interface for storing and retrieving values by key.
-
CacheFirstStrategy<P extends RequestParams, R>
-
A cache strategy that always attempts to serve data from cache first.
-
CacheStrategy<P extends RequestParams, R>
-
Defines a strategy for handling requests with caching support.
-
CacheThenRefreshStrategy<P extends RequestParams, R>
-
A cache strategy that delivers cached data immediately (if available),
then refreshes it with a newly fetched value.
-
ChainedSourcesRepo<P1 extends RequestParams, P2 extends RequestParams, R1, R2, E>
-
A repository implementation that chains two DataSources,
where the second source depends on the result of the first.
-
DataError<E>
-
Indicates that an error occurred while loading data.
-
DataInitial<E>
-
Indicates that the repository's data has been explicitly cleared
via a flush operation, and no data is currently available.
-
DataLoading<E>
-
Indicates that data is currently being loaded.
-
DataSource<P extends RequestParams, R>
-
A generic data source interface for executing requests,
managing lifecycle, and exposing request states.
-
DataState<E>
-
Represents the state of data in a repository or request flow.
-
DataSuccess<E>
-
Indicates that data has been successfully loaded.
-
KeyValueStoreInterface
-
A simple interface for key-value storage systems.
-
NoOpCacheStrategy<P extends RequestParams, R>
-
A no-op cache strategy that performs no caching at all.
-
PeriodicRepo<P extends RequestParams, R, E>
-
A repository implementation that periodically fetches data from
a DataSource at a fixed
interval.
-
Repo<P extends RequestParams, E>
-
A generic repository interface for managing data fetching,
state streaming, and lifecycle control.
-
RequestError<P extends RequestParams, R>
-
Indicates that a request has failed.
-
RequestInitial<P extends RequestParams, R>
-
Indicates the initial state before any request has been made.
-
RequestLoading<P extends RequestParams, R>
-
Indicates that a request is currently in progress.
-
RequestParams
-
Base interface for defining request parameters.
-
RequestPayload<P extends RequestParams, R>
-
Represents the base class for all request states.
-
RequestSuccess<P extends RequestParams, R>
-
Indicates that a request has successfully completed.
-
RequestVersion
-
A simple counter used to track request versions.
-
SingleSourceRepo<P extends RequestParams, R, E>
-
A repository implementation that consumes a single DataSource
and exposes mapped entities of type
E.
-
StreamBoxErrorObserver
-
Interface for observing errors emitted by repositories.
-
StreamBoxErrorObservers
-
Singleton manager for global error observers.
Typedefs
-
ValueFetcher<R>
= Future<R> Function()
-
A function type that defines an asynchronous value fetcher.
