PathRecordingDependencyVisitor
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 benull
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 benull
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. Iftrue
, all recorded paths will have only one matching node (namely the terminal node), iffalse
a recorded path can consist of multiple matching nodes.

Method Details
-
getFilter
Gets the filter being used to select terminal nodes.- Returns:
- The filter being used or
null
if none.
-
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
.
