public NodeVisitor begin()

null
is returned, the ast is not traversed.
begin
in class NodeVisitor
NodeVisitor
to traverse the ast with. If
null
is returned, the ast is not traversed.public NodeVisitor enter(Node n)
NodeVisitor
n
. This gives
the visitor the option of changing internal state or returning a new
visitor which will be used to visit the children of n
.
This method is typically called by the method
enter(parent, n)
. If a subclass overrides the
method enter(parent, n)
then this method
may not be called.
enter
in class NodeVisitor
n
- The root of the subtree to be traversed.
NodeVisitor
which should be used to visit the
children of n
.public Node leave(Node old, Node n, NodeVisitor v)
NodeVisitor
n
have been visited. In this case, these children were visited by the
visitor v
. This is the last chance for the visitor to
modify the tree rooted at n
. This method will be called
exactly the same number of times as entry
is called.
That is, for each node that is not overriden, enter
and
leave
are each called exactly once.
Note that if old == n
then the vistior should make a copy
of n
before modifying it. It should then return the
modified copy.
This method is typically called by the method
leave(parent, old, n v)
.
If a subclass overrides the method
leave(parent, old, n v)
then this method may not be called.
leave
in class NodeVisitor
old
- The original state of root of the current subtree.n
- The current state of the root of the current subtree.v
- The NodeVisitor
object used to visit the children.
