## com.vividsolutions.jts.planargraph
Class DirectedEdgeStar

    java.lang.Object
      com.vividsolutions.jts.planargraph.DirectedEdgeStar

public class DirectedEdgeStar
extends java.lang.Object

A sorted collection of `DirectedEdge`s which leave a `Node` in a `PlanarGraph`.

Version:
  1.7

Field Summary
`protected java.util.List` | `outEdges` The underlying list of outgoing DirectedEdges

Constructor Summary
`DirectedEdgeStar()` Constructs a DirectedEdgeStar with no edges.

Method Summary
`void` | `add(DirectedEdge de)` Adds a new member to this DirectedEdgeStar.
`Coordinate` | `getCoordinate()` Returns the coordinate for the node at wich this star is based
`int` | `getDegree()` Returns the number of edges around the Node associated with this DirectedEdgeStar.
`java.util.List` | `getEdges()` Returns the DirectedEdges, in ascending order by angle with the positive x-axis.
`int` | `getIndex(DirectedEdge dirEdge)` Returns the zero-based index of the given DirectedEdge, after sorting in ascending order by angle with the positive x-axis.
`int` | `getIndex(Edge edge)` Returns the zero-based index of the given Edge, after sorting in ascending order by angle with the positive x-axis.
`int` | `getIndex(int i)` Returns the remainder when i is divided by the number of edges in this DirectedEdgeStar.
`DirectedEdge` | `getNextEdge(DirectedEdge dirEdge)` Returns the DirectedEdge on the left-hand side of the given DirectedEdge (which must be a member of this DirectedEdgeStar).
`java.util.Iterator` | `iterator()` Returns an Iterator over the DirectedEdges, in ascending order by angle with the positive x-axis.
`void` | `remove(DirectedEdge de)` Drops a member of this DirectedEdgeStar.
