public class TLcdXYZFloatPolyline extends ALcd3DEditableFloatPolypoint implements ILcd3DEditablePolyline
ILcd3DEditablePolyline in
the cartesian space with a reduced memory footprint.
It uses an array of floats instead of a TLcd3DEditablePointList
of ILcd3DEditablePoint objects. A single array of floats
stores the 3D coordinates. The points are stored as (x,y,z) triplets.
The array can also contain the bounds of the polyline in the the last 6 places. Whether or not this is the case is controlled by a boolean passed at construction time. These bounds are then stored as (x,y,z)(width,height,depth).
This class is thread-hostile, even for read-only access, since point instances are being reused from an internal pool.
| Constructor and Description |
|---|
TLcdXYZFloatPolyline()
Constructs an empty polyline, containing zero points.
|
TLcdXYZFloatPolyline(float[] aCoordinates,
boolean aHasBounds,
boolean aBoundsInitialized,
boolean aClone)
Constructs an XYZ polyline with the points as given in the array.
|
TLcdXYZFloatPolyline(TLcdXYZFloatPolyline aXYZFloatPolyline)
Clones the array of the polyline passed and interprets the its values alike (containing bounds or not).

ALcdShapeObject.clone(). Extensions should delegate to this implementation
with super.clone(), in order to create an object instance of
the right type, with all fields copied. They then should explicitly
clone any non-primitive fields for which a deeper clone is required.clone in interface ILcdCloneableclone in class ALcd3DEditableFloatPolypointObject.clone()protected ILcd3DEditablePoint createPoint()
