Class Curve

Curve class

A Curve is a sequence of points.

public abstract class Curve : Geometry, ICurve

Properties

NameDescription
CoordinateDimension { get; }Gets the number of coordinate dimensions for this Geometry.
Dimension { get; }Gets the topological dimension of this Geometry.
abstract EndPoint { get; }Returns a copy of the end point of the curve.
abstract GeometryType { get; }Gets the type of the geometry.
virtual HasCurveGeometry { get; }Gets a value indicating whether this geometry is or contains curve (not linear) geometry.
virtual HasM { get; set; }Gets a value indicating whether this instance has M coordinate.
virtual 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.
virtual 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.
abstract SpatialReferenceSystem { get; set; }Gets SpatialReferenceSystem of this instance. This property can be null, is SpatialReferenceSystem is unknown. Assigning new SpatialReferenceSystem will not perform any coordinate transformation, only reference will change.
abstract StartPoint { get; }Returns a copy of the starting point of the curve.
