Interface TreeTransformer
public interface TreeTransformer
This is a simple interface for a function that alters a
local Tree
.
- Author:

transformTree
Tree transformTree(Tree t)
- Does whatever one needs to do to a particular tree.
This routine is passed a whole
Tree
, and could itself
work recursively, but the canonical usage is to invoke this method
via the Tree.transform()
method, which will apply the
transformer in a bottom-up manner to each local Tree
,
and hence the implementation of TreeTransformer
should
merely examine and change a local (one-level) Tree
.
- Parameters:
t
- A tree. Classes implementing this interface can assume
that the tree passed in is not null
.
- Returns:
- the transformed
Tree
