LineSegmentContainer (Macrofocus TreeMap API for Swing SpecificationA good and efficient starting point is the use of the SwingTreeMap component. It contains all the information to get started within minutes!To use this API, please make sure you have at least (this is the absolute minimum) the macrofocus-treemap-swing.jar, macrofocus-treemap.jar, macrofocus-common.jar, macrofocus-visualization.jar, and macrofocus-slider.jar libraries in your class path.)

java.lang.Object
- com.macrofocus.treemap.voronoi.smoothing.LineSegmentContainer

```
public class LineSegmentContainer
extends java.lang.Object
```
This class is a container for LineSegments. LineSegments are smooth connecting splines between corners (or vertexes) of voronoi cell outline shapes. If a LineSegment in the opposite direction (exchanged start and end points) already exists in the container it will not be added again.

  - addIfNotContained
```
public SegmentDirection addIfNotContained(LineSegment lineSegmentToAdd)
```
    Adds a line segment only if a line segment in the opposite direction (exchanged start and end points) not already exists in the container.
    
    Parameters:
    
    lineSegmentToAdd - the line segment to be added
    
    Returns:
    
    the dorection with which the segement further can be used. Forward if the segent has not yet existed or already exists in the same direction as the line segment to add. Reverse if the segment already exist in the opposite direction.
  - getReference
```
public LineSegment getReference(LineSegment currentSegment)
```
    Returns the reference to the corresponding line segment in the container. If it has to be use forward or backwards tells the addIfNotContained() method. Can but does not have to be the same object as the currentSegment parameter.
    
    Parameters:
    
    currentSegment - segment of which a reference from the container is returned.
    
    Returns:
    
    the reference to the corresponding line segment in the container. If it has to be use forward or backwards tells the addIfNotContained() method. Can but does not have to be the same object as the currentSegment parameter.
