Direct Known Subclasses:

DirectedEdgeStar, EdgeEndBundleStar
```
public abstract class EdgeEndStar
extends java.lang.Object
```
A EdgeEndStar is an ordered list of EdgeEnds around a node. They are maintained in CCW order (starting with the positive x-axis) around the node for efficient lookup and topology building.

- Method Detail
  - insert
```
public abstract void insert(EdgeEnd e)
```
    Insert a EdgeEnd into this EdgeEndStar
    
    Parameters:
    
    e - EdgeEnd
  - getCoordinate
```
public Coordinate getCoordinate()
```
    Returns:
    
    the coordinate for the node this star is based at
  - getDegree
```
public int getDegree()
```
  - iterator
```
public java.util.Iterator iterator()
```
    Iterator access to the ordered list of edges is optimized by copying the map collection to a list. (This assumes that once an iterator is requested, it is likely that insertion into the map is complete).
    
    Returns:
    
    access to ordered list of edges
