public class TLcdLonLatFloatPolylineCache extends TLcdLonLatFloatPolyline implements ILcdCache
ILcd2DEditablePolyline in
the geodetic space.
Calculations are based on a spherical approximation.
It uses an array of floats instead of a TLcd2DEditablePointList
of ILcd2DEditablePoint objects. A single array of floats
stores the 2D coordinates. The points are stored as (x,y) pairs.
The boolean indicates whether the last 4 places in the array can be used
to store the bounds of the ILcd2DEditablePolyline.
This class is thread-hostile, even for read-only access, since point instances are being reused from an internal pool.

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 TLcdLonLatFloatPolylineObject.clone()
