+# ProxyAllocator::GetStats
+
+```cpp
+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：** 无
+
+**返回：** Stats 结构体 const 引用
+
+**复杂度：** O(1)
+
+**示例：**
+
+```cpp
+#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));
+```
