Field Detail

### coord

    protected Coordinate coord

### edges

    protected EdgeEndStar edges

Constructor Detail

### Node

    public Node(Coordinate coord,
                EdgeEndStar edges)

Method Detail

### getCoordinate

    public Coordinate getCoordinate()

  Specified by:
    `getCoordinate` in class `GraphComponent`
  Returns:
    a coordinate in this component (or null, if there are none)

### getEdges

    public EdgeEndStar getEdges()

### isIncidentEdgeInResult

    public boolean isIncidentEdgeInResult()

  Tests whether any incident edge is flagged as being in the result. This test can be used to determine if the node is in the result, since if any incident edge is in the result, the node must be in the result as well.

  Returns:
    `true` if any indicident edge in the in the result

### isIsolated

    public boolean isIsolated()

  Description copied from class: `GraphComponent`
  An isolated component is one that does not intersect or touch any other component. This is the case if the label has valid locations for only a single Geometry.

  Specified by:
    `isIsolated` in class `GraphComponent`
  Returns:
    true if this component is isolated

### computeIM

    protected void computeIM(IntersectionMatrix im)

  Basic nodes do not compute IMs

  Specified by:
    `computeIM` in class `GraphComponent`

### add

    public void add(EdgeEnd e)

  Add the edge to the list of edges at this node

### mergeLabel

    public void mergeLabel(Node n)

### mergeLabel

    public void mergeLabel(Label label2)

  To merge labels for two nodes, the merged location for each LabelElement is computed. The location for the corresponding node LabelElement is set to the result, as long as the location is non-null.

### setLabel

    public void setLabel(int argIndex,
                         int onLocation)

### setLabelBoundary

    public void setLabelBoundary(int argIndex)

  Updates the label of a node to BOUNDARY, obeying the mod-2 boundaryDetermination rule.

### print

    public void print(java.io.PrintStream out)
