DependencyFilter |
getFilter()
Gets the filter being used to select terminal nodes.
|
List<List<DependencyNode>> |
getPaths()
Gets the paths leading to nodes matching the filter that have been recorded during the graph visit.
|
boolean |
visitEnter(DependencyNode node)
Notifies the visitor of a node visit before its children have been processed.
|
boolean |
visitLeave(DependencyNode node)
Notifies the visitor of a node visit after its children have been processed.

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.public DependencyFilter getFilter()
