R - the return type of this visitor's methodsP - the type of the additional parameter to this visitor's methods.public interface AnnotationValueVisitor<R,P>
boolean values versus int values. Classes
implementing this interface are used to operate on a value when the
type of that value is unknown at compile time. When a visitor is
passed to a value's accept method,
the visitXYZ method applicable to that value is
invoked.
Classes implementing this interface may or may not throw a
NullPointerException if the additional parameter p
is 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. To avoid this source incompatibility, visitor implementations are encouraged to instead extend the appropriate abstract visitor class that implements this interface. However, an API should generally use this visitor interface as the type for parameters, return type, etc. rather than one of the abstract classes.
Note that methods to accommodate new language constructs could
be added in a source compatible way if they were added as
default methods. However, default methods are only
available on Java SE 8 and higher releases and the javax.lang.model.* packages bundled in Java SE 8 are required to
also be runnable on Java SE 7. Therefore, default methods
cannot be used when extending javax.lang.model.*
to cover Java SE 8 language features. However, default methods may
be used in subsequent revisions of the javax.lang.model.*
packages that are only required to run on Java SE 8 and higher
platform versions.
