LinearAllocator::GetTotalAllocated

size_t GetTotalAllocated() const override;

返回自分配器创建以来的累计分配字节数。对于线性分配器,这等于当前已使用的字节数(m_offset)。

参数:

返回: 累计已分配的字节数

复杂度: O(1)

示例:

#include <XCEngine/Memory/LinearAllocator.h>

LinearAllocator allocator(1024);

size_t total1 = allocator.GetTotalAllocated(); // 0

allocator.Allocate(256);
allocator.Allocate(128);

size_t total2 = allocator.GetTotalAllocated(); // 384

allocator.Clear();

size_t total3 = allocator.GetTotalAllocated(); // 0Clear 后重置)
