java.lang.Object

cloud.opencode.base.feature.strategy.EnvironmentStrategy

All Implemented Interfaces:

public class EnvironmentStrategy
extends Object
implements EnableStrategy

Environment-Based Enable Strategy 基于环境的启用策略

Strategy that enables/disables features based on the deployment environment.

根据部署环境启用/禁用功能的策略。

Environment Resolution Order | 环境解析顺序:

1. Context attribute "environment" - 上下文属性 "environment"
2. System property "app.environment" - 系统属性 "app.environment"
3. Environment variable "APP_ENVIRONMENT" - 环境变量 "APP_ENVIRONMENT"
4. Default: "default" - 默认: "default"

Usage Examples | 使用示例:

EnvironmentStrategy strategy = EnvironmentStrategy.builder()
    .dev(true)
    .staging(true)
    .prod(false)
    .defaultState(false)
    .build();

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

Security | 安全性:

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

Since:

JDK 25, opencode-base-feature V1.0.3
