IEnumPointAndDistance Interface

Provides access to members that iterate over the points on a geometry that are closest to an input point, as returned by QueryPointsAndDistances.

Description

The IEnumPointAndDistance enumerator is used with the ICurve3::QueryPointsAndDistances method.

Members

	Name	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_Attribute	Sets attribute values at the current vertex.
	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.
