Class SimpleTypeVisitor6<R,P>
- java.lang.Object
-
- javax.lang.model.util.AbstractTypeVisitor6<R,P>
-
- javax.lang.model.util.SimpleTypeVisitor6<R,P>
-
- Type Parameters:
-
R
- the return type of this visitor's methods. UseVoid
for visitors that do not need to return results. -
P
- the type of the additional parameter to this visitor's methods. UseVoid
for visitors that do not need an additional parameter.
- All Implemented Interfaces:
- TypeVisitor<R,P>
- Direct Known Subclasses:
- SimpleTypeVisitor7, TypeKindVisitor6
@SupportedSourceVersion(value=RELEASE_6) public class SimpleTypeVisitor6<R,P> extends AbstractTypeVisitor6<R,P>
A simple visitor of types with default behavior appropriate for theRELEASE_6
source version. Visit methods corresponding toRELEASE_6
language constructs calldefaultAction
, passing their arguments todefaultAction
's corresponding parameters. For constructs introduced inRELEASE_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.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.
