| id | Hierarchy item identifier. |
| outInstanceIds | List filled with InstanceID values of merged samples as a result of a method call. |
Retrieves the instanceID of the merged samples corresponding to a hierarchy item.
When HierarchyFrameDataView uses ViewMode.MergeSamplesWithTheSameName mode, multiple samples with the same name at the same hierarchy level are merged together and are represented by a single item. Respectively GetItemColumnData in this case represents an aggregated value.
GetItemMergedSamplesColumnData allows to obtain values of individual samples in merged hierarchy.
The result is written to outInstanceIds list which is resized if necessary.
