public class TLcdGXYSinglePlacementLabelingAlgorithm
extends TLcdGXYLabelPainterLocationLabelingAlgorithm

This labeling algorithm is a greedy labeling algorithm that only tries one placement per label. It tries to place all labels at location index 0, unless a label is sticky or edited by a label editor.

This algorithm also uses a forced painting threshold priority to force labels to be placed, even if they overlap with other labels, see TLcdGXYLabelPainterLocationLabelingAlgorithm.setForcedPaintingThresholdPriority(int).

The implementation of this labeling algorithm is thread-safe if the set label priority provider is thread-safe.

Method Detail

clone

public TLcdGXYSinglePlacementLabelingAlgorithm 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 TLcdGXYLabelPainterLocationLabelingAlgorithm
