PoolAllocator::GetAllocationCount

size_t GetAllocationCount() const override;

返回当前已分配块的数量。计算公式：m_totalBlocks - m_freeBlocks。

参数： 无

返回： 当前已分配块的数量

复杂度： O(1)

示例：

#include <XCEngine/Memory/PoolAllocator.h>

PoolAllocator pool(sizeof(int), 100);

size_t count = pool.GetAllocationCount(); // 0

void* blocks[10];
for (int i = 0; i < 10; ++i) {
    blocks[i] = pool.Allocate();
}

count = pool.GetAllocationCount(); // 10

for (int i = 0; i < 5; ++i) {
    pool.Free(blocks[i]);
}

count = pool.GetAllocationCount(); // 5
