Class CircularArcBy3PointsAbstract

Circular-arc-by-3-points interface. A circular-arc-by-3-points is a Shape that represents a circular arc defined by 3 points in the 2D space.

The circular-arc-by-3-points is defined by:

A circular-arc-by-3-points cannot be instantiated directly. It must be instantiated using createCircularArcBy3Points.

Accessors

Abstract bounds

  • get bounds(): Bounds

  • The bounds of this shape. This property is to be treated in a read only manner. An error will be thrown when trying to assign to this property. Note that the bounds property is not immutable. Modifying properties of the bounds property may corrupt your data.

    Returns Bounds

Abstract center

  • get center(): Point

  • The center point of the circle defining the circular arc. This field is read-only.

    Please use move2DToCoordinates or move2DToPoint to move the center point to a new position.

    Returns Point

Abstract coordinateType

  • get coordinateType(): CoordinateType

  • The coordinate type this shape. This property is read only. An Error will be thrown when trying to assign to this property.

    Returns CoordinateType

Abstract endPoint

  • get endPoint(): Point

  • The end point of this circular arc. This is one of the three points defined in a circular-arc-by-3-points. This field is read-only.

    Returns Point

Abstract focusPoint

  • get focusPoint(): Point

  • The focus point of this shape. This property is read only. An error will be thrown when trying to assign to this property. This property contains an object but should be treated with value semantics: changes to the shape will not be reflected in the focusPoint that was retrieved from this Polygon before the modification.

    Returns Point

Abstract intermediatePoint

Abstract radius

  • get radius(): number

  • The radius of the circle defining the circular arc.

    Returns number

reference

  • get reference(): null | CoordinateReference

  • The spatial reference of this shape. This property is read only. An Error will be thrown when trying to assign to this property.

    Returns null | CoordinateReference

Abstract startAzimuth

  • get startAzimuth(): number

  • The start angle. It is defined as an azimuth: in degrees, positive clockwise, starting up/north.

    Returns number

Abstract startPoint

  • get startPoint(): Point

  • The start point of this circular arc. This is one of the three points defined in a circular-arc-by-3-points. This field is read-only.

    Returns Point

Abstract sweepAngle

  • get sweepAngle(): number

  • The angle over which the arc extends. It is defined in degrees, positive clockwise.

    Returns number

type

Methods

contains2D

  • Determines whether a given point is inside this shape. This method checks containment only in two dimensions: on the (x,y)-axis or the (lon,lat)-axis (depending on the spatial reference of the shape).

    Parameters

    • x: number | Point | Bounds

      The point for which containment must be checked. If a 3D point is passed to this function, it will be treated as a 2D point: the z coordinate (height) will be ignored. The reference of this point must be the same reference as this Shape

    • Optional y: number

    Returns boolean

    true when the given point is contained in this shape

    Throws

    Point with another spatial reference

    Deprecated

    Please use contains2DPoint instead.

Abstract contains2DCoordinates

  • Determines whether the given point is inside this shape. This method checks containment only in two dimensions: on the (x,y)-axis or the (lon,lat)-axis (depending on the spatial reference of the shape).

    Parameters

    • x: number

      The x coordinate of the point for which containment must be checked

    • y: number

      The y coordinate of the point for which containment must be checked

    Returns boolean

    true when the given point is contained in this shape

    Throws

    Point with another spatial reference

contains2DPoint

  • Determines whether the given point is inside this shape. This method checks containment only in two dimensions: on the (x,y)-axis or the (lon,lat)-axis (depending on the spatial reference of the shape).

    Parameters

    • point: Point

      The point for which containment must be checked.

    Returns boolean

    true when the given point is contained in this shape

    Throws

    Point with another spatial reference

Abstract copy

equals

  • Indicates whether this shape is equal to another.

    Parameters

    • aArc: Shape

      the other shape this shape is compared with.

    Returns boolean

    true if both shapes are equal, false otherwise.
