override LookupNearest :
values : IEnumerable<'T> *
direction : Direction -> int[] Parameters
- values
- Type: System.Collections.GenericIEnumerableT
A sequence of keys to locate in the index. - direction
- Type: Extreme.DataAnalysisDirection
The direction to look for the key if an exact match is not found.
Return Value
Type:
Int32An array containing the mapped position of the elements of
values.
If a nearest key was found in the index, then the mapped position is the zero-based
position of the first occurance of the value in the index;
otherwise the mapped position is -1.
