Interface Action

All Known Implementing Classes:
CompositeAction, ConsumerAction
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 Action
Action Interface - Rule Action Abstraction 动作接口 - 规则动作抽象

Represents an action to be executed when a rule fires.

表示规则触发时要执行的动作。

Features | 主要功能:

  • Context modification - 上下文修改
  • Result setting - 结果设置
  • Chainable execution - 可链式执行

Usage Examples | 使用示例:

// Simple action
Action action = ctx -> ctx.setResult("discount", 0.1);

// Chained actions
Action combined = action1.andThen(action2);

Security | 安全性:

  • Thread-safe: Implementation dependent - 线程安全: 取决于实现
  • Null-safe: No (context must not be null) - 空值安全: 否（上下文不能为null）
Since:
JDK 25, opencode-base-rules V1.0.0
