enter

public final TreeVisit.ETreeVisitResult enter(Node node,
                                              List<TreeVisit.TreePathFragment<Node>> path)

Description copied from interface: TreeVisit.ITreeVisitor

Enters a tree node. This is called when the node is first reached, before any visitor methods are called on child nodes. See TreeVisit for an example of the call order.

Specified by:

enter in interface TreeVisit.ITreeVisitor<Node>

Parameters:

node - A tree node.

path - The path of the node, i.e. all parents of the node. This is always an empty list when includePath is set to false

Returns:

How to proceed with the tree visit.

exit

public final boolean exit(Node node,
                          List<TreeVisit.TreePathFragment<Node>> path)

Description copied from interface: TreeVisit.ITreeVisitor

Exists a tree node. This is called at the end, after all children were visited. No more visitor methods will be called on any children of the node. See TreeVisit for an example of the call order.

Specified by:

exit in interface TreeVisit.ITreeVisitor<Node>

Parameters:

node - A tree node.

path - The path of the node, i.e. all parents of the node. This is always an empty list when includePath is set to false

Returns:

true to continue with the tree visit, false to exit the visit (see TreeVisit.ETreeVisitResult.QUIT).

visit

public final boolean visit(Node node,
                           List<TreeVisit.TreePathFragment<Node>> path)

Description copied from interface: TreeVisit.ITreeVisitor

Visits a tree node. This is called between enter and exit. See TreeVisit for an example of the call order.

Specified by:

visit in interface TreeVisit.ITreeVisitor<Node>

Parameters:

node - A tree node.

path - The path of the node, i.e. all parents of the node. This is always an empty list when includePath is set to false
