cloud.opencode.base.cron.exception.OpenCronException

All Implemented Interfaces:

Serializable

public class OpenCronException
extends RuntimeException

Cron Exception - Exception for Cron Expression Errors Cron异常 - Cron表达式错误异常

Thrown when cron expression parsing, validation, or evaluation fails. Carries diagnostic context including the original expression and the problematic field name.

当Cron表达式解析、验证或计算失败时抛出。 携带诊断上下文，包括原始表达式和有问题的字段名称。

Features | 主要功能:

• Diagnostic fields: expression, field name - 诊断字段：表达式、字段名称
• Factory methods for common error types - 常见错误类型的工厂方法
• Serializable - 可序列化

Usage Examples | 使用示例:

throw OpenCronException.parseError("invalid", "expected 5 or 6 fields");
throw OpenCronException.fieldError("hour", 25, 0, 23);

Security | 安全性:

• Thread-safe: Yes (immutable exception) - 线程安全: 是（不可变异常）
• Null-safe: No - 空值安全: 否

Since:

JDK 25, opencode-base-cron V1.0.0
