identify
Identifies all the elements in the GeometryEditor, at the given screen point.
As locations from user gestures are not always accurate to the exact pixel, you can define a tolerance for the identify operation. The tolerance parameter sets the radius of a circle, centered at the specified coordinates, in device-independent pixels (DIP). If the tolerance value is 0, identify performs the test at the specified coordinate. If it is greater than 0, identify tests completely within the circle. For touch displays a value of 22 is recommended to cover an average finger tap. The maximum allowed value is 100 DIPs.
The default tolerance values used by the geometry editor for each input type are:
Mouse device - 5 DIPs.
Stylus device - 10 DIPs.
Touch - 15 DIPs.
Reticle tool - 5 DIPs.
This operation will fail if:
No GeometryEditor is attached to the MapView.
The attached GeometryEditor is stopped.
Return
A Result of IdentifyGeometryEditorResult containing an array of GeometryEditorElement or failure if there is no GeometryEditor. Results are returned in the same order as the draw order of GeometryEditorElements on the GeometryEditor display; that is top-first order, with GeometryEditorVertex appearing drawn on-top of other elements.

Parameters
