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).

. 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
