# IAllocator::GetTotalAllocated
|
|
|
|
```cpp
|
|
virtual size_t GetTotalAllocated() const = 0;
|
|
```
|
|
|
|
返回此分配器自创建以来累计分配的字节总数。这是一个只读查询操作，不会修改任何内部状态。
|
|
|
|
**参数：** 无
|
|
|
|
**返回：** 累计已分配的字节数
|
|
|
|
**复杂度：** O(1)
|
|
|
|
**示例：**
|
|
|
|
```cpp
|
|
#include <XCEngine/Memory/IAllocator.h>
|
|
|
|
class MyAllocator : public IAllocator {
|
|
size_t m_allocated = 0;
|
|
public:
|
|
void* Allocate(size_t size, size_t alignment = 0) override {
|
|
void* ptr = ::operator new(size);
|
|
m_allocated += size;
|
|
return ptr;
|
|
}
|
|
|
|
void Free(void* ptr) override {
|
|
if (ptr) ::operator delete(ptr);
|
|
}
|
|
|
|
void* Reallocate(void* ptr, size_t newSize) override { /* ... */ }
|
|
|
|
size_t GetTotalAllocated() const override { return m_allocated; }
|
|
size_t GetTotalFreed() const override { return 0; }
|
|
size_t GetPeakAllocated() const override { return m_allocated; }
|
|
size_t GetAllocationCount() const override { return 0; }
|
|
const char* GetName() const override { return "MyAllocator"; }
|
|
};
|
|
|
|
MyAllocator alloc;
|
|
alloc.Allocate(100);
|
|
alloc.Allocate(200);
|
|
size_t total = alloc.GetTotalAllocated(); // 返回 300
|
|
```
