Class CompositeStrategy

java.lang.Object
cloud.opencode.base.feature.strategy.CompositeStrategy
All Implemented Interfaces:
EnableStrategy
public class CompositeStrategy extends Object implements EnableStrategy
Composite Strategy 组合策略

Strategy that combines multiple strategies with AND/OR logic.

使用AND/OR逻辑组合多个策略的策略。

Features | 主要功能:

  • AND logic (allOf) - AND逻辑（全部满足）
  • OR logic (anyOf) - OR逻辑（任一满足）
  • Complex conditions - 复杂条件

Usage Examples | 使用示例:

// AND: must be VIP user AND within date range
EnableStrategy strategy = CompositeStrategy.allOf(
    new UserListStrategy(Set.of("vip1", "vip2")),
    new DateRangeStrategy(start, end)
);

// OR: VIP user OR 50% rollout
EnableStrategy strategy = CompositeStrategy.anyOf(
    new UserListStrategy(Set.of("vip1")),
    new PercentageStrategy(50)
);

Security | 安全性:

  • Thread-safe: Yes - 线程安全: 是
  • Null-safe: Partial (validates inputs) - 空值安全: 部分（验证输入）
