当然可以!我可以帮你实现一个简单的 UML 状态图,使用 C++ 的面向对象方法。首先,我们需要定义状态(State)和转移(Transition)两个类。状态类表示一个状态节点,转移类表示状态之间的转换。
以下是一个简单的实现示例:
```cpp
#include <iostream>
#include <vector>
// 状态类
class State {
public:
State(const std::string& name) : name(name) {}
std::string getName() const {
return name;
}
private:
std::string name;
};
// 转移类
class Transition {
public:
Transition(State* from, State* to, const std::string& event)
: from(from), to(to), event(event) {}
State* getFromState() const {
return from;
}
State* getToState() const {
return to;
}
std::string getEvent() const {
return event;
}
private:
State* from;
State* to;
std::string event;
};
int main() {
// 创建状态
State* state1 = new State("State 1");
State* state2 = new State("State 2");
State* state3 = new State("State 3");
// 创建转移
Transition* transition1 = new Transition(state1, state2, "Event 1");
Transition* transition2 = new Transition(state2, state3, "Event 2");
Transition* transition3 = new Transition(state3, state1, "Event 3");
// 存储所有状态和转移
std::vector<State*> states = {state1, state2, state3};
std::vector<Transition*> transitions = {transition1, transition2, transition3};
// 输出状态和转移信息
for (const auto& state : states) {
std::cout << "State: " << state->getName() << std::endl;
}
for (const auto& transition : transitions) {
std::cout << "Transition: " << transition->getEvent() << std::endl;
std::cout << "From: " << transition->getFromState()->getName() << std::endl;
std::cout << "To: " << transition->getToState()->getName() << std::endl;
}
// 释放内存
for (const auto& state : states) {
delete state;
}
for (const auto& transition : transitions) {
delete transition;
}
return 0;
}
```
这个示例创建了三个状态(State)对象:State 1、State 2 和 State 3,并创建了三个转移(Transition)对象,分别表示从一个状态到另一个状态的转换。最后,我们打印出所有的状态和转移信息。
当然,这只是一个简单的示例,你可以根据实际需求进行扩展和修改。希望对你有所帮助!
