Class NodeMap

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

public class NodeMap
extends java.lang.Object

A map of `Node`s, indexed by the coordinate of the node.

Version:
  1.7

Constructor Summary
`NodeMap()` Constructs a NodeMap without any Nodes.

Method Summary
`Node` | `add(Node n)` Adds a node to the map, replacing any that is already at that location.
`Node` | `find(Coordinate coord)` Returns the Node at the given location, or null if no Node was there.
`java.util.Iterator` | `iterator()` Returns an Iterator over the Nodes in this NodeMap, sorted in ascending order by angle with the positive x-axis.
`Node` | `remove(Coordinate pt)` Removes the Node at the given location, and returns it (or null if no Node was there).
`java.util.Collection` | `values()` Returns the Nodes in this NodeMap, sorted in ascending order by angle with the positive x-axis.
