Class AbstractTypeVisitor6<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:

@SupportedSourceVersion(RELEASE_6) public abstract class AbstractTypeVisitor6<R,P> extends Object implements TypeVisitor<R,P>
RELEASE_6
source version.- API Note:
-
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 and subclasses 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 directly or indirectly call the
visitUnknown
method. A new abstract 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 a new visitor is introduced, portions of this visitor class may be deprecated, including its constructors. - Since:
- 1.6

p
- a visitor-specified parameter - Returns:
- a visitor-specified result
visit
public final R visit(TypeMirror t)

UnionType
element by callingvisitUnknown

- a visitor-specified result
- Throws:
-
UnknownTypeException
- a visitor implementation may optionally throw this exception
