-/**
- * A simple implementation of the TreeVisitor for ECMAScript edition 5.1.
- *
- * <p>The visit methods corresponding to ES 5.1 language constructs walk the
- * "components" of the given tree by calling accept method passing the
- * current visitor and the additional parameter.
- *
- * <p>For constructs introduced in later versions, {@code visitUnknown}
- * is called instead which throws {@link UnknownTreeException}.
- *
- * <p> Methods in this class may be overridden subject to their
- * general contract.  Note that annotating methods in concrete
- * subclasses with {@link java.lang.Override @Override} will help
- * ensure that methods are overridden as intended.
- *
- * @deprecated Nashorn JavaScript script engine and APIs, and the jjs tool
- * are deprecated with the intent to remove them in a future release.
- *
- * @param <R> the return type of this visitor's methods.  Use {@link
- *            Void} for visitors that do not need to return results.
- * @param <P> the type of the additional parameter to this visitor's
- *            methods.  Use {@code Void} for visitors that do not need an
- *            additional parameter.
