      • PathRecordingDependencyVisitor

        public PathRecordingDependencyVisitor​(org.eclipse.aether.graph.DependencyFilter filter)
        Creates a new visitor that uses the specified filter to identify terminal nodes of interesting paths. The visitor will not search for paths going beyond an already matched node.
        Parameters:
        filter - The filter used to select terminal nodes of paths to record, may be null to match any node.
      • PathRecordingDependencyVisitor

        public PathRecordingDependencyVisitor​(org.eclipse.aether.graph.DependencyFilter filter,
                                              boolean excludeChildrenOfMatches)
        Creates a new visitor that uses the specified filter to identify terminal nodes of interesting paths.
        Parameters:
        filter - The filter used to select terminal nodes of paths to record, may be null to match any node.
        excludeChildrenOfMatches - Flag controlling whether children of matched nodes should be excluded from the traversal, thereby ignoring any potential paths to other matching nodes beneath a matching ancestor node. If true, all recorded paths will have only one matching node (namely the terminal node), if false a recorded path can consist of multiple matching nodes.

      • getFilter

        public org.eclipse.aether.graph.DependencyFilter getFilter()
        Gets the filter being used to select terminal nodes.
        Returns:
        The filter being used or null if none.
      • getPaths

        public java.util.List<java.util.List<org.eclipse.aether.graph.DependencyNode>> getPaths()
        Gets the paths leading to nodes matching the filter that have been recorded during the graph visit. A path is given as a sequence of nodes, starting with the root node of the graph and ending with a node that matched the filter.
        Returns:
        The recorded paths, never null.
      • visitEnter

        public boolean visitEnter​(org.eclipse.aether.graph.DependencyNode node)
        Specified by:
        visitEnter in interface org.eclipse.aether.graph.DependencyVisitor
      • visitLeave

        public boolean visitLeave​(org.eclipse.aether.graph.DependencyNode node)
        Specified by:
        visitLeave in interface org.eclipse.aether.graph.DependencyVisitor
