Provides access to members that iterate over the points on a geometry that are closest to an input point, as returned by QueryPointsAndDistances.
Product Availability
Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.
Description
The IEnumPointAndDistance enumerator is used with the ICurve3::QueryPointsAndDistances method.
Members
Description | ||
---|---|---|
Clone | Returns a copy of this enumerator positioned at the same vertex. | |
ContinuousSectionAfter | Indicates whether the current point and the next point lie on a circular arc with the query point at its center. | |
ContinuousSectionBefore | Indicates whether the current point and the previous point lie on a circular arc with the query point at its center. | |
DistanceAlongCurve | Gives the distance along the curve from the curve's from point to the current postion. | |
IsLastInPart | Indicates if the current vertex is last in the current part. | |
Next | Returns the next vertex and its location within the geometry. | |
NextInPart | Returns the next vertex in current part, or goes back to the first vertex in the part after last vertex in part is encountered. | |
OnRightSide | Indicates whether the query point is to the right of the curve at the current position. | |
Previous | Returns the previous vertex and its location in the geometry. | |
put_ID | Sets the ID attribute of the current vertex. For segment-based geometries, this will modify a pair of segments. | |
put_M | Sets the M attribute of the current vertex. For segment-based geometries, this will modify a pair of segments. | |
put_X | Sets the X coordinate of the current vertex. For segment-based geometries, this will modify a pair of segments. | |
put_Y | Sets the Y coordinate of the current vertex. For segment-based geometries, this will modify a pair of segments. | |
put_Z | Sets the Z coordinate of the current vertex. For segment-based geometries, this will modify a pair of segments. | |
QueryNext | Copies the next vertex to the input parameter and returns its location in the geometry. | |
QueryNextInPart | Copies the next vertex in the current part to the input parameter and returns its location in current part. Continues with the first vertex in the part if already at the end. | |
QueryPrevious | Copies the previous vertex to the input parameter and returns its location in the geometry. | |
Reset | Starts from the beginning of the geometry the next time Next is called. | |
ResetToEnd | Starts from the end of the geometry the next time Previous is called. | |
SetAt | Resets enumerator to specific location. | |
Skip | Skips forward or backward over a specified number of vertices. |
