    public class BuildingDependencyNodeVisitor
extends java.lang.Object
implements org.apache.maven.shared.dependency.graph.traversal.DependencyNodeVisitor
    A dependency node visitor that clones visited nodes into a new dependency tree. This can be used in conjunction with a dependency node filter to construct subtrees.
