Direct Known Subclasses:

Type0Visitor, Type1UpVisitor, Type1Visitor

public abstract class AscendVisitor

extends TreeVisitor

AscendVisitor is the superclass of Type0Visitor and Type1Visitor, conveniently containing the common code. It makes an upward traversal of the tree as if it were a binary tree (nodes with more than two children, such as a method call, are considered in a form similar to curried form).
