Copy full snippet

namespace TraceServices {     template<typename ItemType, typename PageType>     FInt32Interval TraceServices&58;&58;GetElementRangeOverlappingGivenRange     &40;         const TPagedArray< ItemType, PageType > & PagedArray,         double StartTime,         double EndTime,         TFunctionRef< double(const ItemType &)> ItemStartProjection,         TFunctionRef< double(const ItemType &)> ItemEndProjection     &41; }

Remarks

Use binary search to find the first and last element inside a TPagedArray that overlaps a given input interval. This requires the elements in the array to be sorted by the value returned from the Projection. Example usage for Timeline events would require a projection that returns Item.StartTime and the resulting range.Min will point to the last element where Item.End > StartTime and range.Max to the last element where Item.StartTime < EndTime.
