BloomJsonStorage class

JSON object storage with optional TTL expiration.

Encapsulates serialization and deserialization of typed JSON records with automatic expiration pruning.

Example:

final jsonStorage = BloomJsonStorage(FileStorageAdapter());
await jsonStorage.set('user_profile', {'name': 'Alice', 'role': 'admin'}, ttl: const Duration(hours: 1));
final profile = await jsonStorage.get<Map<String, dynamic>>('user_profile');

inherited

readJson<T>(String key) → Future<T?>

Alias for get to retrieve a stored JSON object.

set<T>(String key, T value, {Duration? ttl, Duration? expiresIn}) → Future<void>

Stores a JSON-encodable value with optional ttl or expiresIn duration.

toString() → String

A string representation of this object.

inherited

writeJson<T>(String key, T value, {Duration? ttl, Duration? expiresIn}) → Future<void>
