我试图声明一个priority_queue of nodes,bool Compare(Node a, Node b)用作比较器函数(在节点类之外).
我现在拥有的是:
priority_queue<Node, vector<Node>, Compare> openSet;
出于某种原因,我得到了 Error: "Compare" is not a type name
将声明更改为 priority_queue <Node, vector<Node>, bool Compare>
给我 Error: expected a '>'
我也尝试过:
priority_queue<Node, vector<Node>, Compare()> openSet;
priority_queue<Node, vector<Node>, bool Compare()> openSet;
priority_queue<Node, vector<Node>, Compare<Node, Node>> openSet;
我应该如何正确地宣布我的priority_queue？
