Class 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.

    • 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
