ProxyAllocator::GetStats

const Stats& GetStats() const;

返回详细的统计信息结构体引用。包含累计分配、累计释放、峰值分配、分配次数和额外开销。返回 const 引用,无锁开销(内部已有互斥保护)。

参数:

返回: Stats 结构体 const 引用

复杂度: O(1)

示例:

#include <XCEngine/Memory/MemoryManager.h>
#include <XCEngine/Memory/ProxyAllocator.h>

IAllocator* sysAlloc = MemoryManager::Get().GetSystemAllocator();
ProxyAllocator proxy(sysAlloc, "FrameData");

proxy.Allocate(1024);
proxy.Allocate(512);
proxy.Free(proxy.Allocate(256));

const ProxyAllocator::Stats& stats = proxy.GetStats();
printf("Total allocated: %zu bytes\n", stats.totalAllocated);
printf("Total freed: %zu times\n", stats.totalFreed);
printf("Peak allocated: %zu bytes\n", stats.peakAllocated);
printf("Allocation count: %zu\n", stats.allocationCount);
printf("Memory overhead: %zu bytes\n", stats.memoryOverhead);
printf("Current in use: %zu bytes\n",
    stats.totalAllocated - stats.allocationCount * sizeof(/* typical block */ size_t));
