Description

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

Use HierarchyFrameDataView to retrieve Profiler samples structured as a hierarchy.
This is used in the Hierachy mode of the CPU Usage Profiler, for example.

The HierarchyFrameDataView aggregates the data with time and memory information. Each hierarchy item includes accumulated data of its children.

using System;
using System.Collections.Generic;
using UnityEditor.Profiling;
using UnityEditorInternal;

public class Example { List<int> parentsCacheList = new List<int>(); List<int> childrenCacheList = new List<int>();

public void ProcessFrameData(int frame) { using (var frameData = ProfilerDriver.GetHierarchyFrameDataView(frame, 0, HierarchyFrameDataView.ViewModes.Default, HierarchyFrameDataView.columnGcMemory, false)) { int rootId = frameData.GetRootItemID(); frameData.GetItemDescendantsThatHaveChildren(rootId, parentsCacheList); foreach (int parentId in parentsCacheList) { frameData.GetItemChildren(parentId, childrenCacheList); // Process further records } } } }

Static Properties

columnCallsThe Calls column.
columnDontSortThe column identifier that indicates whether sorting is disabled.
columnGcMemoryThe amount of managed allocations within a sample.
columnNameThe Profiler Sample Name column.
columnObjectNameThe Object Name column.
columnSelfPercentThe percentage of the CPU time Unity spends in a sample itself, excluding the time from child samples.
columnSelfTimeThe CPU time in milliseconds that Unity spends in a sample itself, excluding the time from child samples.
columnStartTimeThe start time of a call in milliseconds.
columnTotalPercentThe percentage of the CPU time Unity spends in a sample, including the time from child samples.
columnTotalTimeThe CPU time in milliseconds that Unity spends in a sample, including the time from child samples.
columnWarningCountThe amount of samples that are inside a code execution path that is suboptimal for performance.
invalidSampleIdIndex of the invalid item.

Properties

sortColumnThe column identifier that defines the sort column.
sortColumnAscendingWhether the sorting order is ascending, true, or descending, false.
viewModeThe view mode which defines how data is aggregated.
