Package Summary Overview Summary |
R
- the return type of this visitor's methods. Use Void
for visitors that do not need to return results. P
- the type of the additional parameter to this visitor's methods. Use Void
for visitors that do not need an additional parameter. @SupportedSourceVersion(value=RELEASE_8) public class SimpleTypeVisitor8<R,P> extends SimpleTypeVisitor7<R,P>
RELEASE_7
source version. Visit methods corresponding to RELEASE_8
and earlier language constructs call defaultAction
, passing their arguments to defaultAction
's corresponding parameters. 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.
