java.lang.Objectedu.stanford.nlp.parser.lexparser.BoundaryRemover
public class BoundaryRemover
Removes a boundary symbol (Lexicon.BOUNDARY_TAG or Lexicon.BOUNDARY), which is the rightmost daughter of a tree. Otherwise does nothing. This is needed because the dependency parser uses such symbols. Note: the transformTree method is destructive.

TreeTransformer

, 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
.
