Description

Provides access to the Profiler data for a specific frame and thread.

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; } }

Static Properties

invalidSampleIndexThis constant defines a sample index that does not match any valid Profiler Sample.
