# PoolAllocator::GetTotalBlockCount

```cpp
size_t GetTotalBlockCount() const;
```

返回内存池中的总块数。此值在构造时确定，之后保持不变。

**参数：** 无

**返回：** 内存池的总块数

**复杂度：** O(1)

**示例：**

```cpp
#include <XCEngine/Memory/PoolAllocator.h>

PoolAllocator pool(sizeof(int), 100);

size_t total = pool.GetTotalBlockCount(); // 100
size_t free = pool.GetFreeBlockCount();  // 100

void* block = pool.Allocate();
size_t freeAfter = pool.GetFreeBlockCount(); // 99

pool.Free(block);
size_t freeRestored = pool.GetFreeBlockCount(); // 100
```
