org.sonatype.aether.util.graph.PreorderNodeListGenerator
- 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.
