Check(GeoPoint, IGeoObject, SnapPointFinder.DidSnapModes)

The IGeoObject obj offers the point p as a snappoint in the given mode. This method checks whether to use this point as the closest snap point. This method is typically called by GeoObjects from the FindSnapPoint(SnapPointFinder) method.

Declaration

public void Check(GeoPoint p, IGeoObject obj, SnapPointFinder.DidSnapModes mode)

Parameters

Type	Name	Description
GeoPoint	p
IGeoObject	obj
SnapPointFinder.DidSnapModes	mode
