All Implemented Interfaces:

DependencyVisitor

public class PreorderNodeListGenerator
extends AbstractDepthFirstNodeListGenerator

Generates a sequence of dependency nodes from a dependeny graph by traversing the graph in preorder. This visitor visits each node exactly once regardless how many paths within the dependency graph lead to the node such that the resulting node sequence is free of duplicates.
