public interface TreeVisitor<R,P>
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'saccept
method, thevisitXyz
method most applicable to that tree is invoked.Classes implementing this interface may or may not throw a
NullPointerException
if the additional parameterp
isnull
; 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, language 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.
