Class ThrowException

java.lang.Object
cloud.opencode.base.id.snowflake.ThrowException
All Implemented Interfaces:
ClockBackwardStrategy
public final class ThrowException extends Object implements ClockBackwardStrategy
Throw Exception Strategy for Clock Backward Handling 时钟回拨抛异常策略

Immediately throws an exception when clock backward is detected. This is the strictest strategy, suitable for scenarios that cannot tolerate any clock inconsistency.

检测到时钟回拨时立即抛出异常。这是最严格的策略， 适用于不能容忍任何时钟不一致的场景。

Features | 主要功能:

  • Singleton instance - 单例实例
  • Fail-fast behavior - 快速失败行为
  • Zero tolerance for clock backward - 对时钟回拨零容忍

Usage Examples | 使用示例:

ClockBackwardStrategy strategy = ThrowException.getInstance();

SnowflakeGenerator gen = SnowflakeBuilder.create()
    .clockBackwardStrategy(ThrowException.getInstance())
    .build();

Security | 安全性:

  • Thread-safe: Yes - 线程安全: 是
