# 内存池MemoryPool
- 模板类型为class时 使用格式如下
```cpp
struct hi
{
hi() {}
vector a;
~hi() {}
};
qmem::SingleDataTypeMemoryPool sd2;
//allocate 获取内存
//自动调用构造函数
hi* qw = sd2.allocate();
//归还内存
sd2.deallocate(qw);
```
- 不同内存池之间的性能
```cpp
{
//模板类型为class时 使用格式如下
qmem::SingleDataTypeMemoryPool sd2;
//allocate 获取内存
//自动调用构造函数
hi* qw = sd2.allocate();
//归还内存
sd2.deallocate(qw);
}
{
//允许单个类型获取内存的内存池，不允许生成数组
//release 获取内存和释放内存平均耗时 1.597e-08s
qmem::SingleDataTypeMemoryPool sd;
clock_t start = clock();
for (size_t i = 0; i < times; ++i)
{
a[i] = sd.allocate();
}
for (size_t i = 0; i < times; ++i)
{
sd.deallocate(a[i]);
}
cout << "SingleDataTypeMemoryPool：" << static_cast(clock() - start) / CLOCKS_PER_SEC / times << '\n';
}
{
//标准库内存池
//release 获取内存和释放内存平均耗时 9.122e-08s
allocator stdAllocator;
clock_t start = clock();
for (size_t i = 0; i < times; ++i)
{
a[i] = stdAllocator.allocate(1);
}
for (size_t i = 0; i < times; ++i)
{
stdAllocator.deallocate(a[i], 1);
}
cout << "allocator：" << static_cast(clock() - start) / CLOCKS_PER_SEC / times << '\n';
}
```
