cloud.opencode.base.graph.exception.GraphException

cloud.opencode.base.graph.exception.NoPathException

All Implemented Interfaces:

Serializable

public class NoPathException
extends GraphException

No Path Exception 无路径异常

Exception thrown when no path exists between two vertices.

当两个顶点之间不存在路径时抛出的异常。

Features | 主要功能:

• Carries source and target vertex information - 携带源顶点和目标顶点信息
• Extends GraphException with GraphErrorCode.NO_PATH - 使用NO_PATH错误码扩展GraphException

Usage Examples | 使用示例:

try {
    // operation requiring path existence
} catch (NoPathException e) {
    Object source = e.getSource();
    Object target = e.getTarget();
}

Security | 安全性:

• Thread-safe: Yes (immutable after construction) - 线程安全: 是（构造后不可变）
• Null-safe: Yes - 空值安全: 是

Since:

JDK 25, opencode-base-graph V1.0.0
