ResourceDependencyGraph::HasCircularDependency

bool HasCircularDependency(ResourceGUID guid, Containers::Array<ResourceGUID>& outCycle) const

检测是否存在以指定节点为起点的循环依赖。使用 DFS 遍历依赖图,检测回路。

参数:

  • guid - 起始节点
  • outCycle - 输出参数,检测到的循环路径(包含形成环的节点 GUID

返回: 如果存在循环依赖则返回 true否则返回 false

复杂度: O(n + e)

示例:

Containers::Array<ResourceGUID> cycle;
if (graph.HasCircularDependency(guid, cycle)) {
    printf("Circular dependency detected: ");
    for (const auto& g : cycle) {
        printf("%llu ", g.value);
    }
}
