A skeletal visitor for annotation values with default behavior
appropriate for the RELEASE_6
source version.

 WARNING: The AnnotationValueVisitor interface
implemented by this class may have methods added to it in the
future to accommodate new, currently unknown, language structures
added to future versions of the Java™ programming language.
Therefore, methods whose names begin with "visit" may be
added to this class in the future; to avoid incompatibilities,
classes which extend this class should not declare any instance
methods with names beginning with "visit".

When such a new visit method is added, the default
implementation in this class will be to call the visitUnknown method.  A new abstract annotation
value visitor class will also be introduced to correspond to the
new language level; this visitor will have different default
behavior for the visit method in question.  When the new visitor is
introduced, all or portions of this visitor may be deprecated.

Note that adding a default implementation of a new visit method
in a visitor class will occur instead of adding a default
method directly in the visitor interface since a Java SE 8
language feature cannot be used to this version of the API since
this version is required to be runnable on Java SE 7

import static javax.lang.model.util.ElementFilter.*;

Filters for selecting just the elements of interest from a
collection of elements.  The returned sets and lists are new
collections and do use the argument as a backing store.  The
methods in this class do not make any attempts to guard against
concurrent modifications of the arguments.  The returned sets and
lists are mutable but unsafe for concurrent access.  A returned set
has the same iteration order as the argument set to a method.

If iterables and sets containing null are passed as
arguments to methods in this class, a NullPointerException
will be thrown.

Note that a static import statement can make the text of
calls to the methods in this class more concise; for example:

Utility methods for operating on program elements.

Compatibility Note: Methods may be added to this interface

A scanning visitor of program elements with default behavior
appropriate for the RELEASE_6
source version.  The visitXYZ methods in this
class scan their component elements by calling scan on
their enclosed elements,
parameters, etc., as
indicated in the individual method specifications.  A subclass can
control the order elements are visited by overriding the
visitXYZ methods.  Note that clients of a scanner
may get the desired behavior be invoking v.scan(e, p) rather
than v.visit(e, p) on the root objects of interest.

When a subclass overrides a visitXYZ method, the
new method can cause the enclosed elements to be scanned in the
default way by calling super.visitXYZ.  In this
fashion, the concrete visitor can control the ordering of traversal
over the component elements with respect to the additional
processing; for example, consistently calling
super.visitXYZ at the start of the overridden
methods will yield a preorder traversal, etc.  If the component
elements should be traversed in some other order, instead of
calling super.visitXYZ, an overriding visit method
should call scan with the elements in the desired order.

level; this visitor will have different default behavior for the
visit method in question.  When the new visitor is introduced, all
or portions of this visitor may be deprecated.

Note that adding a default implementation of a new visit method
in a visitor class will occur instead of adding a default
method directly in the visitor interface since a Java SE 8
language feature cannot be used to this version of the API since
this version is required to be runnable on Java SE 7
implementations.  Future versions of the API that are only required
to run on Java SE 8 and later may take advantage of default methods
in this situation.

A simple visitor of types with default behavior appropriate for the
RELEASE_6 source version.

Visit methods corresponding to RELEASE_6 language
constructs call defaultAction, passing their
arguments to defaultAction's corresponding parameters.

For constructs introduced in RELEASE_7 and later, visitUnknown is called instead.

 Methods in this class may be overridden subject to their
general contract.  Note that annotating methods in concrete
subclasses with @Override will help
ensure that methods are overridden as intended.

 WARNING: The TypeVisitor interface implemented
by this class may have methods added to it in the future to
accommodate new, currently unknown, language structures added to
future versions of the Java™ programming language.
Therefore, methods whose names begin with "visit" may be
added to this class in the future; to avoid incompatibilities,
classes which extend this class should not declare any instance
methods with names beginning with "visit".

When such a new visit method is added, the default
implementation in this class will be to call the visitUnknown method.  A new simple type visitor
class will also be introduced to correspond to the new language
level; this visitor will have different default behavior for the
visit method in question.  When the new visitor is introduced, all
or portions of this visitor may be deprecated.

A visitor of types based on their javax.lang.model.type.kind with
