|
||
|
|
|
||
|
|
```cpp
|
||
|
|
size_t GetBlockSize() const;
|
||
|
|
```
|
||
|
|
|
||
|
|
返回内存池中每个内存块的大小。此值在构造时确定，之后保持不变。
|
||
|
|
|
||

**参数：** 无
|
||
|
|
|
||
|
|
**返回：** 每个内存块的字节大小
|
||
|
|
|
||
|
|
**复杂度：** O(1)

|
|
|
||

```cpp
|
||
|
|
#include <XCEngine/Memory/PoolAllocator.h>
|
||
|
|
|
||
|
|
PoolAllocator pool(sizeof(int) * 100, 50);
|
||
|
|
|
||
|
|
size_t blockSize = pool.GetBlockSize(); // 400 字节
|
||
|
|
|
||
|
|
void* block = pool.Allocate();
|
||
|
|
int* arr = static_cast<int*>(block);
|
||
|
|
// arr 指向的大小为 blockSize 字节的内存块
|
||
|
|
```
