 public static final int IN

 private static char hexchars_[]
o dataTypes 
 public static String dataTypes[]

o data_ 
 private String data_[]
o defaults 
 public static Node defaults
The default node. Created nodes are initialized with the fields of this node. Default attributes can be changed by modifying it, in the same way those attributes are changed for other nodes.

For Example: If Node.defaults.setPosition(1.0, 1.0) is called, (1.0, 1.0) becomes the default position for all Nodes created thereafter.

Do not assign defaults to null, but it can be assigned to another Node.

Constructors

o Node 
 private Node(int unused)
o Node 
 public Node()
Create a Node with default attributes.

o Node 
 public Node(boolean dummy)
Create a Node with default attributes, that may be a dummy node. Graph.dummysToEdgePaths() will convert the dummy nodes to edge paths.
