public class TLcdXYZFloatPolypoint
extends ALcd3DEditableFloatPolypoint
implements ILcd3DEditablePolypoint

This class provides an implementation of ILcd3DEditablePolypoint 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 polypoint in 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 Details

TLcdXYZFloatPolypoint

public TLcdXYZFloatPolypoint()

Constructs an empty polypoint, containing zero points. No space is reserved to store the bounds of the polypoint.

TLcdXYZFloatPolypoint

public TLcdXYZFloatPolypoint(float[] aCoordinates,
 boolean aHasBounds,
 boolean aBoundsInitialized,
 boolean aClone)

Constructs an XYZ polypoint with the points as given in the array. If aHasBounds is true, the last 6 entries of the array will be used to store the bounds of the polypoint.

Parameters:

aCoordinates - an array containing the coordinates of the points and possibly the bounds of the polypoint.

aHasBounds - whether to reserve the last 6 entries of the array for the bounds of the polypoint or not.

aBoundsInitialized - whether the last 6 entries of the array passed represent the calculated values of the bounds of the polypoint or not. This is only of importance when aHasBounds is true.

aClone - whether the array containing the coordinates (and possibly the bounds) should be cloned.

TLcdXYZFloatPolypoint

public TLcdXYZFloatPolypoint(TLcdXYZFloatPolypoint aXYZFloatPolypoint)

Clones the array of the polypoint passed and interprets the its values alike (containing bounds or not).

Parameters:

aXYZFloatPolypoint - the polypoint to assume all values from.

Method Details

clone

public Object clone()

Description copied from class: ALcdShape

Creates and returns a copy of this object, by delegating to Object.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.

Specified by:

clone in interface ILcdCloneable

Overrides:

clone in class ALcd3DEditableFloatPolypoint

createPoint

protected ILcd3DEditablePoint createPoint()

Description copied from class: ALcd3DEditableFloatPolypoint

Creates an uninitialized ILcd3DEditablePoint point of a type compatible with the concrete implementation of this class (geodesic/cartesian). The created point will be updated and returned by the ALcd3DEditableFloatPolypoint.getPoint(int) and ALcd3DEditableFloatPolypoint.getFocusPoint() methods.

Specified by:

createPoint in class ALcd3DEditableFloatPolypoint

createBounds

protected ILcd3DEditableBounds createBounds()

Description copied from class: ALcd3DEditableFloatPolypoint

Creates an uninitialized ILcd3DEditableBounds object of a type compatible with the concrete implementation of this class. This bounds object will be updated and returned by the ALcd3DEditableFloatPolypoint.getBounds() method.

Specified by:

createBounds in class ALcd3DEditableFloatPolypoint
