Examples of GraphGenerator

com.impetus.kundera.graph.GraphGenerator
@author vivek.mishraResponsible for: 1. Do pre-checks a) validation entity b) set id c) check for shared via primary key { on parse relation } d) dirty check { on associated and self entity } 2. Parse through relations and relational objects. 3. Recursively process transitive relations
org.apache.oozie.util.GraphGenerator
Class to generate and plot runtime workflow DAG
org.geotools.graph.build.GraphGenerator
Contructs a graph based on relationships between the entities (objects) modelled by the graph.

The underlying graph is generated by continually adding objects to the generator. The Generator determines the relationships between the objects and decides how to model the relationship and the objects themselves in the graph.

The GraphGenerator is the upper level of the graph construction process. It is a wrapper around the GraphBuilder class that is intended to instruct the builder how to build the underyling graph structure. @see GraphBuilder @author Justin Deoliveira, Refractions Research Inc, jdeolive@refractions.net @source $URL$

Creates/updates the graph containing visualised nodes and edges. Listeners can register themselves with the GraphGenerator so that they are informed about changes to the Graph.
