- Constructor Detail
  - PolygonizeDirectedEdge
```
public PolygonizeDirectedEdge(Node from,
                              Node to,
                              Coordinate directionPt,
                              boolean edgeDirection)
```
    Constructs a directed edge connecting the from node to the to node.
    
    Parameters:
    
    directionPt - specifies this DirectedEdge's direction (given by an imaginary line from the from node to directionPt)
    
    edgeDirection - whether this DirectedEdge's direction is the same as or opposite to that of the parent Edge (if any)
