/**
* A visitor of trees, in the style of the visitor design pattern.
* Classes implementing this interface are used to operate
* on a tree when the kind of tree is unknown at compile time.
* When a visitor is passed to an tree's {@link DocTree#accept
* accept} method, the visitXYZ method most applicable
* to that tree is invoked.
*
* Classes implementing this interface may or may not throw a
* {@code NullPointerException} if the additional parameter {@code p}
* is {@code null}; see documentation of the implementing class for
* details.
*
*
WARNING: It is possible that methods will be added to
* this interface to accommodate new, currently unknown, doc comment
* structures added to future versions of the Java™ programming
* language. Therefore, visitor classes directly implementing this
* interface may be source incompatible with future versions of the
* platform.
*
* @param the return type of this visitor's methods. Use {@link
* Void} for visitors that do not need to return results.
* @param the type of the additional parameter to this visitor's
* methods. Use {@code Void} for visitors that do not need an
* additional parameter.

* @since 1.8
