Provides access to members that iterate over collections of segments (obtained from the EnumSegments property on the ISegmentCollection interface).

Description

The methods on IEnumSegment interface can be used to access segments of a segment collection. Those methods are more efficient than the ISegmentCollection methods to access a large number of segments in a sequential order for polyline and polygon. The collection methods transform absolute segment index into a part relative index, enumerators don't.

Members

	All Properties Methods	Description
	Clone	Returns a copy of this enumerator positioned at the same segment.
	IsLastInPart	Indicates if the current segment is last in the current part.
	IsRecycling	Indicates if this enumerator re-uses the same segment each time next is called.
	Next	Returns the next segment, and its location in the collection. If the location does not have parts (i.e. a path or ring) then the part index will always be zero.
	NextEx	Populates a segment info structure with information on the next segment in the collection.
	NextInPart	Returns the next segment in current part, goes back to first segment after last segment in part is encountered.
	NextInPartEx	Returns the next segment info structure in current part, goes back to first segment after last segment in part is encountered.
	Previous	Returns the previous segment in this segment collection.
	Reset	Starts from the beginning of the segment collection the next time Next is called.
	ResetToEnd	Starts from the end of the path, ring, polyline or polygon the next time Previous is called.
	SetAt	Resets enumerator to specific location.
	Skip	Skips forward or backward over a specified number of segments.
