Enum Class GraphErrorCode

java.lang.Object
java.lang.Enum<GraphErrorCode>
cloud.opencode.base.graph.exception.GraphErrorCode
All Implemented Interfaces:
Serializable, Comparable<GraphErrorCode>, Constable
public enum GraphErrorCode extends Enum<GraphErrorCode>
Graph Error Code 图错误码

Error codes for graph operations.

图操作的错误码。

Features | 主要功能:

  • Categorized error codes (1xxx structure, 2xxx algorithm, 3xxx validation, 4xxx resource) - 分类错误码
  • Numeric code and description for each error - 每个错误的数字代码和描述

Usage Examples | 使用示例:

GraphErrorCode code = GraphErrorCode.CYCLE_DETECTED;
int numericCode = code.getCode();          // 2001
String desc = code.getDescription();       // "Cycle detected"

Security | 安全性:

  • Thread-safe: Yes (immutable enum) - 线程安全: 是（不可变枚举）
  • Null-safe: Yes - 空值安全: 是
Since:
JDK 25, opencode-base-graph V1.0.0
