All Implemented Interfaces:

ElementTransform

public class ElementTransformSubst
extends ElementTransformCopyBase

An ElementTransform which replaces occurrences of a variable with a Node value. Because a Var is a subclass of Node_Variable which is a Node, this includes variable renaming.

This is a transformation on the syntax - all occurrences of a variable are replaced, even if inside sub-select's and not project (which means it is effectively a different variable).
