Interface EnableStrategy

All Known Implementing Classes:

AlwaysOffStrategy, AlwaysOnStrategy, CompositeStrategy, ConsistentPercentageStrategy, DateRangeStrategy, EnvironmentStrategy, ExpressionStrategy, PercentageStrategy, TenantAwareStrategy, UserListStrategy

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface EnableStrategy

Enable Strategy Interface 启用策略接口

Interface for feature enablement strategies.

功能启用策略的接口。

Features | 主要功能:

• Feature evaluation - 功能评估
• Context-aware decision - 上下文感知决策
• Composable strategies - 可组合策略

Built-in Strategies | 内置策略:

• AlwaysOnStrategy - Always enabled | 始终启用
• AlwaysOffStrategy - Always disabled | 始终禁用
• PercentageStrategy - Percentage rollout | 百分比灰度
• UserListStrategy - User whitelist | 用户白名单
• DateRangeStrategy - Time-based | 基于时间
• CompositeStrategy - Combined strategies | 组合策略

Usage Examples | 使用示例:

// Custom strategy
EnableStrategy strategy = (feature, context) -> {
    return context.getAttribute("role", "").equals("admin");
};

Feature feature = Feature.builder("admin-feature")
    .strategy(strategy)
    .build();

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
