Package Summary Overview Summary

class:AbstractTypeVisitor6 [NONE]

Type Parameters:

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.

All Implemented Interfaces:

TypeVisitor<R,P>

Direct Known Subclasses:

AbstractTypeVisitor7, SimpleTypeVisitor6
```
@SupportedSourceVersion(RELEASE_6)
public abstract class AbstractTypeVisitor6<R,P>
extends Object
implements TypeVisitor<R,P>
```
A skeletal visitor of types with default behavior appropriate for the RELEASE_6 source version.
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 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 the new visitor is introduced, all or portions of this visitor may be deprecated.

Since:

1.6

Constructor for concrete subclasses to call.

method:visit(javax.lang.model.type.TypeMirror,P) [NONE]

visit
```
public final R visit(TypeMirror t,
                     P p)
```
Visits any type mirror as if by passing itself to that type mirror's accept method. The invocation v.visit(t, p) is equivalent to t.accept(v, p) .

Specified by:

visit in interface TypeVisitor<R,P>

Parameters:

t - the type to visit

p - a visitor-specified parameter

Returns:

a visitor-specified result

method:visit(javax.lang.model.type.TypeMirror) [NONE]

visit
```
public final R visit(TypeMirror t)
```
Visits any type mirror as if by passing itself to that type mirror's accept method and passing null for the additional parameter. The invocation v.visit(t) is equivalent to t.accept(v, null) .

Specified by:

visit in interface TypeVisitor<R,P>

Parameters:

t - the type to visit

Returns:

a visitor-specified result

method:visitUnion(javax.lang.model.type.UnionType,P) [NONE]

visitUnion
```
public R visitUnion(UnionType t,
                    P p)
```
Visits a union type.

Specified by:

visitUnion in interface TypeVisitor<R,P>

Implementation Requirements:

Visits a UnionType element by calling visitUnknown .

Parameters:

t - the type to visit

p - a visitor-specified parameter

Returns:

the result of visitUnknown

Since:

1.7

method:visitIntersection(javax.lang.model.type.IntersectionType,P) [NONE]

visitIntersection
```
public R visitIntersection(IntersectionType t,
                           P p)
```
Visits an intersection type.

Specified by:

visitIntersection in interface TypeVisitor<R,P>

Implementation Requirements:

Visits an IntersectionType element by calling visitUnknown .

Parameters:

t - the type to visit

p - a visitor-specified parameter

Returns:

the result of visitUnknown

Since:

1.8

method:visitUnknown(javax.lang.model.type.TypeMirror,P) [NONE]

visitUnknown
```
public R visitUnknown(TypeMirror t,
                      P p)
```
Visits an unknown kind of type. This can occur if the language evolves and new kinds of types are added to the TypeMirror hierarchy.

Specified by:

visitUnknown in interface TypeVisitor<R,P>

Implementation Requirements:

The default implementation of this method in AbstractTypeVisitor6 will always throw new UnknownTypeException(t, p) . This behavior is not required of a subclass.

Parameters:

t - the type to visit

p - a visitor-specified parameter

Returns:

a visitor-specified result

Throws:

UnknownTypeException - a visitor implementation may optionally throw this exception
