Class PostorderNodeListGenerator
java.lang.Object
org.eclipse.aether.util.graph.visitor.PostorderNodeListGenerator
- All Implemented Interfaces:
DependencyVisitor
Generates a sequence of dependency nodes from a dependeny graph by traversing the graph in postorder. 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.

Method Details

visitEnter
Description copied from interface:DependencyVisitor
Notifies the visitor of a node visit before its children have been processed.- Specified by:
visitEnter
in interfaceDependencyVisitor
- Parameters:
node
- The dependency node being visited, must not benull
.- Returns:
true
to visit child nodes of the specified node as well,false
to skip children.
-
visitLeave
Description copied from interface:DependencyVisitor
Notifies the visitor of a node visit after its children have been processed. Note that this method is always invoked regardless whether any children have actually been visited.- Specified by:
visitLeave
in interfaceDependencyVisitor
- Parameters:
node
- The dependency node being visited, must not benull
.- Returns:
true
to visit siblings nodes of the specified node as well,false
to skip siblings.
-
getNodes
Gets the list of dependency nodes that was generated during the graph traversal.- Returns:
- The list of dependency nodes, never
null
.
-
getDependencies
Gets the dependencies seen during the graph traversal.- Parameters:
includeUnresolved
- Whether unresolved dependencies shall be included in the result or not.- Returns:
- The list of dependencies, never
null
.
-
getArtifacts
Gets the artifacts associated with the list of dependency nodes generated during the graph traversal.- Parameters:
includeUnresolved
- Whether unresolved artifacts shall be included in the result or not.- Returns:
- The list of artifacts, never
null
.
-
getFiles
Gets the files of resolved artifacts seen during the graph traversal.- Returns:
- The list of artifact files, never
null
.
-
getClassPath
Gets a class path by concatenating the artifact files of the visited dependency nodes. Nodes with unresolved artifacts are automatically skipped.- Returns:
- The class path, using the platform-specific path separator, never
null
.
-
setVisited
Marks the specified node as being visited and determines whether the node has been visited before.- Parameters:
node
- The node being visited, must not benull
.- Returns:
true
if the node has not been visited before,false
if the node was already visited.
