Method Detail

transformTree

public Tree transformTree(Tree t)

Description copied from interface: TreeTransformer

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.

Specified by:

transformTree in interface TreeTransformer

Parameters:

t - A tree. Classes implementing this interface can assume that the tree passed in is not null.

Returns:

The transformed Tree
