Class GraphNode

java.lang.Object
  com.iotabits.revisitor.BasicVisitable
      com.iotabits.examples.revisitor.GraphNode

All Implemented Interfaces:

iVisitable

public class GraphNode

extends BasicVisitable

This class provides an example of using the revisitor with a passback. These nodes can be used to represent a directed acyclic graph (DAG).

Nested Class Summary

static class

GraphNode.GraphPrinter Our simple visitor.

Constructor Summary

GraphNode(java.lang.Object data, GraphNode[] children)
ctor

Method Summary

void	accept(iReflectiveVisitor visitor) Graph traversal
GraphNode[]	getChildren() Return all the directly accessible adjacent nodes.
static void	main(java.lang.String[] args) This is a simple test program that constructs a simple graph and then iterates over it using the GraphPrinter visitor class.
void	traverse(iReflectiveVisitor visitor) If we could make the accept private, we would.

Method Detail

getChildren

public GraphNode[] getChildren()

Return all the directly accessible adjacent nodes.

Returns:

accept

public void accept(iReflectiveVisitor visitor)
            throws java.lang.Exception

Graph traversal

Specified by:

accept in interface iVisitable

Overrides:

accept in class BasicVisitable

Parameters:

visitor -

Throws:

java.lang.Exception

traverse

public void traverse(iReflectiveVisitor visitor)
              throws java.lang.Exception

If we could make the accept private, we would. Okay, we could if the reflective visitor where to look up the accept method on the visitable objects and setAccessible to true and so on... but that't too much because we wouldn't do that (or be able to) in the static visitor pattern. This is the method to call to start traversing.

Parameters:

visitor -

Throws:

java.lang.Exception

main

public static void main(java.lang.String[] args)

This is a simple test program that constructs a simple graph and then iterates over it using the GraphPrinter visitor class.

Parameters:

args -
