public class CircularString : Curve, ICircularString
Constructors
| Name | Description |
|---|---|
| CircularString() | Initializes a new instance of the CircularString class. |
| CircularString(ICircularString) | Initializes a new instance of the CircularString class. |
| CircularString(IEnumerable<IPoint>) | Initializes a new instance of the CircularString class. |
Properties
| Name | Description |
|---|---|
| CoordinateDimension { get; } | Gets the number of coordinate dimensions for this Geometry. |
| Count { get; } | Gets the number of points in the CircularString. |
| Dimension { get; } | Gets the topological dimension of this Geometry. |
| override EndPoint { get; } | Returns a copy of the end point of the curve. |
| override GeometryType { get; } | Gets the type of the geometry. |
| override HasCurveGeometry { get; } | Gets a value indicating whether this geometry is or contains curve (not linear) geometry. |
| HasM { get; set; } | Gets a value indicating whether this instance has M coordinate. |
| HasZ { get; set; } | Gets a value indicating whether this instance has Z coordinate. |
| IsClosed { get; } | Gets a values indicating whether a curve is closed. A curve is closed if its start point is equal to its end point. |
| override IsEmpty { get; } | Gets a value indicating whether this instance is empty. |
| IsSimple { get; } | Gets a value indicating whether this instance is simple from SFA point of view. |
| IsValid { get; } | Gets a value indicating whether this instance is valid. |
| Item { get; set; } | Gets or sets the IPoint at the specified index. |
| SpatialReferenceSystem { get; set; } | Gets SpatialReferenceSystem of this instance. This property can be null, if SpatialReferenceSystem is unset. Assigning new SpatialReferenceSystem will not perform any coordinate transformation, only reference will change. |
| override StartPoint { get; } | Returns a copy of the starting point of the curve. |

Remarks
The CircularString consists of one or more circular arc segments connected end to end. The first three points define the first segment. The first point is the start point of the arc. The second point is any intermediate point on the arc other than the start or end point. The third point is the end of the arc. Subsequent arcs are defined by their intermediate and end points only, as the start point is implicitly defined as the previous segment’s end point.
