Public Constructors
public Line ()
Creates a line segment.
Public Methods
public void applyTransformation (Transformation2D transform)
Applies 2D affine transformation in XY plane.
Parameters
| transform | The affine transformation to be applied to this geometry. |
|---|
public double calculateLength2D ()
Calculates the length of the geometry. If the spatial reference is a Geographic
Coordinate System (a system where coordinates are defined using angular units such
as longitude and latitude) then the 2D distance calculation is returned
in angular units. In cases where length must be calculated on a Geographic Coordinate
System consider the using the geodeticLength method in GeometryEngine.
Returns
- A double value representing the 2D length of the geometry.
public int intersectionWithAxis2D (boolean bAxisX, double ordinate, double[] resultOrdinates, double[] parameters)
Calculates intersection points of this segment with an infinite line, parallel to one of the axes.
Parameters
| bAxisX | TRUE if the function works with the line parallel to the axis X. |
|---|---|
| ordinate | The ordinate value of the line (x for axis Y, y for axis X). |
| resultOrdinates | The value of ordinate in the intersection points One ordinate is equal to the ordinate parameter. This parameter can be NULL. |
| parameters | The value of the parameter in the intersection points (between 0 and 1). This parameter can be NULL. |
Returns
- The number of intersection points, 0 when no intersection points exist, -1 when the segment coincides with the line (infinite number of intersection points).
public boolean isCurve ()
Indicates if the line segment is a curve.
public void queryEnvelope (Envelope env)
Gets the axis aligned bounding box of the geometry.
Parameters
| env | The envelope to return the result in. |
