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()
