- - org.eclipse.aether.util.graph.visitor.PreorderNodeListGenerator

All Implemented Interfaces:

DependencyVisitor
```
public final 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.

    visitEnter in class AbstractDepthFirstNodeListGenerator
    
    Parameters:
    
    node - The dependency node being visited, must not be null.
    
    Returns:
    
    true to visit child nodes of the specified node as well, false to skip children.
