public class TLcdASTERIXTrajectory extends Object implements ILcdPointList,ILcdPointList2, ILcdPolyline, ILcdBounded,ILcdFeatured, ILcdCache, ILcdTimeBounded, ILcdDataObject, ILcdCurve
TLcdASTERIXTrajectory models the path of a track (for example an aircraft) flying
from one point to another. The path is discretized, and for every time stamp it contains
the location, heading and additional information of the track.
The number of steps in the discretization can be retrieved using getPointCount().
The locations can be retrieved using getPoint(int), the headings using getTrackHeading(int)
and the additional information is accessible through the getTrackFeature(int, int) method.INTERPOLATION_CIRCLE_BY_3POINTS, INTERPOLATION_CIRCLE_BY_CENTERPOINT, INTERPOLATION_CIRCULARARC_BY_3POINTS, INTERPOLATION_CIRCULARARC_BY_BULGE, INTERPOLATION_CIRCULARARC_BY_CENTERPOINT, INTERPOLATION_ELLIPTICAL, INTERPOLATION_GEODESIC, INTERPOLATION_LINEAR, INTERPOLATION_MIXED, INTERPOLATION_RHUMB| Modifier and Type | Method and Description |

public ILcdBounds getBounds()
ILcdBoundedILcdBounds by which the geometry of this ILcdBounded object
is bounded.
If the geometry does not allow retrieving valid bounds (for example a polyline with 0 points)
the return value is unspecified.
It is highly recommended to return an undefined bounds.
You can create undefined bounds using the default constructors
of TLcdLonLatBounds
or TLcdXYBounds.

ILcdCurve
A set of predefined constants are defined in this interface,
which are used by the default ILcdCurve implementations
provided by LuciadLightspeed.
Custom implementations can define their own constants, and use them to interpret the interpolation of the curve.

ILcdCurveThis information can be used to perform containment calculations, if this curve is closed or if this curve is part of a composite closed curve. By determining the number of intersections between this curve and a line segment starting from a given point in a fixed direction, one can determine whether a point is located within the closed curve by using the even-odd rule.
