public TopLevelClass.Default.Node(List childNodes)
The returned list of getChildNodes()
is the childNodes
rather than a copy of it.
childNodes
- a list of child nodes.Method Detail |

.
For a Node created by the program generated by ¬<><∪∪, the list should be modifiable and the nodes should be ordered by its position in the parsed text. However, the nodes constructed by the users of ¬<><∪∪ are not required to satisfy it.

node.
this
node is passed to the visitor
,
then the child nodes are traversed recursively (preorder traversal).
A node is passed to the methods of the visitor
, using reflection,
that is public, whose name is visit
,
that have only one argument whose type is compatible with this
node,
and that have no throws clause.

This method
replaces oldChild

Also, this method replaces the values returned by TopLevelClass.Type.label()
