hyper_storage library

Classes

BaseStorage

A base class for storage implementations that use a StorageBackend.

HyperStorage

The main entry point for the HyperStorage library, providing centralized storage management with a singleton pattern.

HyperStorageContainer

A concrete implementation of StorageContainer for storing key-value pairs.

InMemoryBackend

A volatile storage backend that stores all data in memory.

ItemHolder<E extends Object>

A basic implementation of ItemHolderApi for simple types.

ItemHolderApi<E extends Object>

Defines the interface for a holder of a single item of type E.

JsonItemHolder<E extends Object>

A JSON-based item holder for managing serialized items.

JsonStorageContainer<E extends Object>

A final implementation of SerializableStorageContainer for JSON-serializable objects.

SerializableItemHolder<E extends Object>

A base class for item holders that manage serialization and deserialization.

SerializableStorageContainer<E extends Object>

An abstract class that provides a container for storing serializable objects of type E.

SerializableStorageOperationsApi<E>

Defines the interface for storage operations on serializable objects of type E.

StorageBackend

An abstract class that defines the contract for a storage backend.

StorageOperationsApi

Defines the interface for basic storage operations.

Mixins

BaseListenable

A mixin that provides functionality for listening..

ItemHolderMixin

A mixin that provides item holder creation methods for a storage and containers.

Typedefs

DeserializeCallback<E> = E Function(String value)

A function that deserializes a string back to an object of type E.

FromJson<E> = E Function(Map<String, dynamic> json)

A function that converts a JSON map to an object of type E.

IdGetter<E> = String Function(E object)

A function that takes an object of type E and returns its ID as a string.

ItemGetter<E extends Object> = Future<E?> Function(StorageBackend backend, String key)

Function type definition for getting an item from the storage backend.

ItemSetter<E extends Object> = Future<void> Function(StorageBackend backend, String key, E value)

Function type definition for setting an item in the storage backend.

ListenableCallback = void Function()

A callback function that takes no arguments and returns no data.

SerializeCallback<E> = String Function(E value)

A function that serializes an object of type E to a string.

ToJson<E> = Map<String, dynamic> Function(E object)

A function that converts an object of type E to a JSON map.
