Returns:

compareTo

public int compareTo(Node arg)

Lexicographic sort order based on (x,y) coordinates

Specified by:

compareTo in interface java.lang.Comparable<Node>

setUserData

public <T> void setUserData(T data)

Store a value of an arbitrary type in this node. This value has no significance for the Node class, but may be convenient for your use.

Type Parameters:

T - The type of data being stored.

Parameters:

data -

getUserData

public <T> T getUserData()

Retrieve the previously stored userData value. Returns null if no value has been stored.

Type Parameters:

T - Type of userData. Must be the same as what was originally stored (or a superclass).
