Class SiteGraph

java.lang.Object
  org.apache.struts2.sitegraph.SiteGraph

public class SiteGraph
extends java.lang.Object

// START SNIPPET: javadocs-intro SiteGraph is a tool that renders out GraphViz-generated images depicting your Struts-powered web application's flow. SiteGraph requires GraphViz be installed and that the "dot" executable be in your command path. You can find GraphViz at http://www.graphviz.org. // END SNIPPET: javadocs-intro

// START SNIPPET: javadocs-api If you wish to use SiteGraph through its API rather than through the command line, you can do that as well. All you need to do is create a new SiteGraph instance, optionally specify a Writer to output the dot content to, and then call prepare(). // END SNIPPET: javadocs-api
