com.sun.source.tree: public interface: TreeVisitor

com.sun.source.tree
public interface: TreeVisitor [javadoc | source]

All Known Implementing Classes:
TreePathScanner, TreeCopier, SimpleTreeVisitor, Copier, IdentAttributer, TreeScanner

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 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, 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.

Parameters:

- the return type of this visitor's methods. Use Void for visitors that do not need to return results.

- the type of the additional parameter to this visitor's methods. Use {@code Void} for visitors that do not need an additional parameter.
