Feature Store Interface 功能存储接口

Interface for storing and retrieving feature definitions.

用于存储和检索功能定义的接口。

Implementations | 实现:

• InMemoryFeatureStore - In-memory storage | 内存存储
• FileFeatureStore - File-based storage | 文件存储
• LruFeatureStore - LRU cache storage | LRU缓存存储

Usage Examples | 使用示例:

FeatureStore store = new InMemoryFeatureStore();
store.save(Feature.builder("feature-1").alwaysOn().build());

Optional<Feature> feature = store.find("feature-1");
List<Feature> all = store.findAll();

Features | 主要功能:

• CRUD operations for feature flag persistence - 功能标志持久化的CRUD操作
• Listener support for change notification - 变更通知的监听器支持

Security | 安全性:

• Thread-safe: Implementation-dependent - 线程安全: 取决于实现
• Null-safe: No - 空值安全: 否

Since:

JDK 25, opencode-base-feature V1.0.0
