# LinearAllocator::GetAllocationCount
```cpp
size_t GetAllocationCount() const override;
```
返回自分配器创建以来的累计分配次数。线性分配器不支持单个块释放,始终返回 0。
**参数:** 无
**返回:** 始终返回 `0`
**复杂度:** O(1)
**示例:**
```cpp
#include <XCEngine/Memory/LinearAllocator.h>
LinearAllocator allocator(1024);
allocator.Allocate(256);
allocator.Allocate(128);
allocator.Allocate(64);
size_t count = allocator.GetAllocationCount(); // 0不支持计数
```
