描述

提供对特定帧和线程的性能分析器数据的访问。

Use RawFrameDataView to retrieve unstructured Profiler samples data for the particular frame.
The order of samples is determined by the order they are generated in the code.

RawFrameDataView can quickly iterate over all samples in the frame without any internal allocations.

public class Example { public static long GetGCAllocs(int frameIndex) { long totalGcAllocSize = 0;

int gcAllocMarkerId = FrameDataView.invalidMarkerId;

for (int threadIndex = 0;; ++threadIndex) { using (RawFrameDataView frameData = ProfilerDriver.GetRawFrameDataView(frameIndex, threadIndex)) { if (!frameData.valid) break;

if (gcAllocMarkerId == FrameDataView.invalidMarkerId) { gcAllocMarkerId = frameData.GetMarkerId("GC.Alloc"); if (gcAllocMarkerId == FrameDataView.invalidMarkerId) break; }

int sampleCount = frameData.sampleCount; for (int i = 0; i < sampleCount; ++i) { if (gcAllocMarkerId != frameData.GetSampleMarkerId(i)) continue;

long gcAllocSize = frameData.GetSampleMetadataAsLong(i, 0); totalGcAllocSize += gcAllocSize; } } }

return totalGcAllocSize; } }
