Class PreorderDependencyNodeConsumerVisitor

java.lang.Object
org.eclipse.aether.util.graph.visitor.PreorderDependencyNodeConsumerVisitor
All Implemented Interfaces:
org.eclipse.aether.graph.DependencyVisitor
public final class PreorderDependencyNodeConsumerVisitor extends Object
Processes dependency 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.

Instances of this class cannot be embedded into FilteringDependencyVisitor, pass in the filter DependencyFilter into constructor instead.

Since:
2.0.0
