ISegmentCollection Interface

Provides access to members that manipulate the segments of a path, ring, polyline, or polygon.

Product Availability

Description

A Segment Collection is a collection of Segments that compose a segment-based geometry.  A Segment Collection can be used to access any segment within a segment-based geometry without regard to the overall geometry that the Segment Collection represents.  As a geometry, the Segment Collection is assumed to be a valid Path.  Although it is possible to access the Segment Collection of an entire Polyline or Polygon, manipulation of Polyline and Polygons is best done with a Geometry Collection.

When To Use

If you are using a development language that does not support C style arrays, use IGeometryBridge instead. The IGeometryBridge interface solves that problem allowing you to pass safe arrays instead.

Members

	Name	Description
	AddSegment	Adds a reference to the input segment at the end, or before or after a specified index.
	AddSegmentCollection	Adds references to the segments from the specified segment collection.
	AddSegments	Adds references to segments. This method is intended for internal use only.
	EnumCurve	A new curve enumerator for this segment collection.
	EnumSegments	A new enumerator for this segment collection.
	HasNonLinearSegments	Indicates if this segment collection contains segments other than lines.
	IndexedEnumSegments	A new indexed segment enumerator for this segment collection.
	InsertSegmentCollection	Inserts references to the segments in the input collectoin.
	InsertSegmentCollectionEx	Inserts references to some of the segments from the input collection.
	InsertSegments	Inserts references to the input segments. This method is intended for internal use only.
	QuerySegments	Returns references to some of the input segments. This method is intended for internal use only.
	RemoveSegments	Removes references to some segments. If closeGap is TRUE, then any remaining internal gap in the path, ring, polyline or polygon is connected with a single line segment.
	ReplaceSegmentCollection	Remove and inserts some segments.
	ReplaceSegments	Removes and inserts from segments. This method is intended for internal use only.
	Segment	A reference to the ith segment.
	SegmentCount	The number of segments.
	SegmentsChanged	Informs the segment collection that any cached values that it may be maintaining (envelope, length, etc.) are invalid. Use this method after editing segments directly.
	SetCircle	Defines this path, ring, polyline or polygon to contain a single circular arc segment that is closed.
	SetRectangle	Defines this path, ring, polyline or polygon to have four line segments in the same positions as the sides of the input envelope.
	SetSegmentCollection	Replaces all segments with references to segments from the input collection.
	SetSegments	Replaces all segments with references to the input segments. This method is intended for internal use only.
	SynchronizeEmptyAttributes	If, at end point shared by two segments, one segment has an empty value for an attribute and the other has a non-empty value, use the non-empty value for both.
