Constructor Detail

• PathRecordingDependencyVisitor

  public PathRecordingDependencyVisitor(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(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.

Method Detail

• getFilter

  public DependencyFilter getFilter()

  Gets the filter being used to select terminal nodes.

  Returns:

  The filter being used or null if none.

• getPaths

  public List<List<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(DependencyNode node)

  Description copied from interface: DependencyVisitor
  Notifies the visitor of a node visit before its children have been processed.

  Specified by:

  visitEnter in interface DependencyVisitor

  Parameters:

  node - The dependency node being visited, must not be null.

  Returns:

  true to visit child nodes of the specified node as well, false to skip children.

• visitLeave

  public boolean visitLeave(DependencyNode node)

  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 interface DependencyVisitor

  Parameters:

  node - The dependency node being visited, must not be null.

  Returns:

  true to visit siblings nodes of the specified node as well, false to skip siblings.
