- 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.

@SupportedSourceVersion(RELEASE_6) public class SimpleTypeVisitor6<R,P> extends AbstractTypeVisitor6<R,P>
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.

Field Detail
DEFAULT_VALUE
protected final R DEFAULT_VALUE
Default value to be returned; defaultAction
returns this value unless the method is overridden.
Constructor Detail
SimpleTypeVisitor6
@Deprecated(since="9") protected SimpleTypeVisitor6()
Constructor for concrete subclasses; uses null
for the default value.
SimpleTypeVisitor6
@Deprecated(since="9") protected SimpleTypeVisitor6(R defaultValue)
Constructor for concrete subclasses; uses the argument for the default value.
- Parameters:
-
defaultValue
- the value to assign toDEFAULT_VALUE
Method Detail
