/**
 * Instances of the class {@code RecursiveElementVisitor} implement an element visitor that will
 * recursively visit all of the element in an element model. For example, using an instance of this
 * class to visit a {@link CompilationUnitElement} will also cause all of the types in the
 * compilation unit to be visited.
 * <p>
 * Subclasses that override a visit method must either invoke the overridden visit method or must
 * explicitly ask the visited element to visit its children. Failure to do so will cause the
 * children of the visited element to not be visited.
