CacheHandler是一个C++模板类,用于实现缓存管理的功能。它可以根据给定的函数,参数,超时时间和最大容量,自动缓存函数的返回值,并在需要时更新缓存。
- 需要包含CacheHandler.h头文件
#include "CacheHandler.h"
// Define a function that takes two integers and returns their sum
double add(int a, int b) {
return a + b;
}
int main() {
// Create a CacheHandler object with add function, 10 seconds timeout and 5 items max size
CacheHandler<double, int, int> cache(add, 10000, 5);
// You can use lambda too
CacheHandler<double, int, int> cache1([](int a, int b) -> double {
return a + b;
}, 10000, 5);
// Get the value of add(1, 2) and cache it
int result = cache.value(1, 2);
std::cout << result << std::endl;
result = cache.value(1, 2);
std::cout << result << std::endl;
return 0;
}
