java.lang.Objectorg.sonatype.aether.util.graph.AbstractDepthFirstNodeListGenerator
public abstract class AbstractDepthFirstNodeListGenerator
Abstract base class for depth first dependency tree traversers. Subclasses of this visitor will visit 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.
Actual vertex ordering (preorder, inorder, postorder) needs to be defined by subclasses through appropriate
implementations for visitEnter(org.sonatype.aether.graph.DependencyNode)
and
visitLeave(org.sonatype.aether.graph.DependencyNode)

List<Artifact> |
getArtifacts(boolean includeUnresolved)
Gets the artifacts associated with the list of dependency nodes generated during the graph traversal. |
String |
getClassPath()
Gets a class path by concatenating the artifact files of the visited dependency nodes. |
List<Dependency> |
getDependencies(boolean includeUnresolved)
Gets the dependencies seen during the graph traversal. |
List<File> |
getFiles()
Gets the files of resolved artifacts seen during the graph traversal. |
List<DependencyNode> |
getNodes()
Gets the list of dependency nodes that was generated during the graph traversal. |
protected boolean |
setVisited(DependencyNode node)
Marks the specified node as being visited and determines whether the node has been visited before. |
abstract boolean |
visitEnter(DependencyNode node)
Notifies the visitor of a node visit before its children have been processed. |
abstract boolean |
visitLeave(DependencyNode node)
Notifies the visitor of a node visit after its children have been processed. |
