LuciadLightspeedClass TLcd2DEditablePointListXYFloatArray

java.lang.Object

com.luciad.shape.shape2D.TLcd2DEditablePointListXYFloatArray

All Implemented Interfaces:

ILcdPointList, ILcd2DEditablePointList, ILcdCloneable, Serializable, Cloneable

public class TLcd2DEditablePointListXYFloatArray
extends Object
implements ILcd2DEditablePointList, ILcdCloneable

This class provides an implementation of ILcd2DEditablePointList. This implementation uses an array of the right size to store the coordinates of the points, which is memory efficient, but inefficient for adding and removing points.

This class is thread-safe for read-only access.

Constructor Detail

TLcd2DEditablePointListXYFloatArray

public TLcd2DEditablePointListXYFloatArray()

Constructs a new empty TLcd2DEditablePointList.

TLcd2DEditablePointListXYFloatArray

public TLcd2DEditablePointListXYFloatArray(float[] aPoints,
                                           boolean aDeepCopy)

Constructs a new TLcd2DEditablePointList that is a copy of the given ILcd2DEditablePointList.

Parameters:

aPoints - an array of x/y coordinates. The n'th point is specified by the values aPoints[2n] (the x) and aPoints[2n+1] (the y).

aDeepCopy - a boolean indicating whether the individual points in the list should be cloned or just referenced.

Method Detail

getPointCount

public final int getPointCount()

Description copied from interface: ILcdPointList

Returns the number of ILcdPoint objects in the list.

Specified by:

getPointCount in interface ILcdPointList

Returns:

the number of ILcdPoint objects in the list.

getPoint

public final ILcdPoint getPoint(int aIndex)

Description copied from interface: ILcdPointList

Returns the ILcdPoint at a given index.

Specified by:

getPoint in interface ILcdPointList

Parameters:

aIndex - a valid index in the list of ILcdPoint objects.

Returns:

the ILcdPoint at the given index.

translate2D

public void translate2D(double aDeltaX,
                        double aDeltaY)

Description copied from interface: ILcd2DEditablePointList

Translates all the points of this ILcd2DEditablePointList from their current positions over the given translation vector in the 2D space. Only the first two dimensions of the points are considered. The third dimension is left unchanged.

                        double aY)

Description copied from interface: ILcd2DEditablePointList

Moves the specified point of this ILcd2DEditablePointList to the given point in the 2D space. Only the first two dimensions of the ILcdShape are considered. The third dimension is left unchanged.

Specified by:

move2DPoint in interface ILcd2DEditablePointList

Parameters:

aIndex - a valid index in the list of points.

aX - the x coordinate of the point.

aY - the y coordinate of the point.

translate2DPoint

public void translate2DPoint(int aIndex,
                             double aDeltaX,
                             double aDeltaY)

Description copied from interface: ILcd2DEditablePointList

Translates the specified point of this ILcd2DEditablePointList from its current position over the given translation vector in the 2D space. Only the first two dimensions of the points are considered. The third dimension is left unchanged.

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

clone

public Object clone()

Description copied from interface: ILcdCloneable

Makes Object.clone() public.

When for example extending from java.lang.Object, it can be implemented like this:

 public Object clone() {
   try {
     return super.clone();
   } catch ( CloneNotSupportedException e ) {
     // Cannot happen: extends from Object and implements Cloneable (see also Object.clone)
     throw new RuntimeException( e );
   }
 }
 

Specified by:

clone in interface ILcdCloneable

Overrides:

clone in class Object
