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.

A skeletal visitor of types with default behavior appropriate for the 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.

Method Detail

visitback to summary
public final R visit(TypeMirror t, P p)

Implements javax.lang.model.type.TypeVisitor.visit.

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).

Parameters
t:TypeMirror

the type to visit

p:P

a visitor-specified parameter

Returns:R

a visitor-specified result

visitback to summary
public final R visit(TypeMirror t)

Overrides default javax.lang.model.type.TypeVisitor.visit.

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).

Parameters
t:TypeMirror

the type to visit

Returns:R

a visitor-specified result

visitIntersectionback to summary
public R visitIntersection(IntersectionType t, P p)

Implements javax.lang.model.type.TypeVisitor.visitIntersection.

Doc from javax.lang.model.type.TypeVisitor.visitIntersection.

Visits an intersection type.

Implementation Specification

Visits an IntersectionType element by calling visitUnknown.

Parameters
t:IntersectionType

the type to visit

p:P

a visitor-specified parameter

Returns:R

the result of visitUnknown

Implements javax.lang.model.type.TypeVisitor.visitUnion.

Doc from javax.lang.model.type.TypeVisitor.visitUnion.

Visits a union type.

Implementation Specification

Visits a UnionType element by calling visitUnknown.

Parameters
t:UnionType

the type to visit

p:P

a visitor-specified parameter

Returns:R

the result of visitUnknown

visitUnknownback to summary
public R visitUnknown(TypeMirror t, P p)

Implements javax.lang.model.type.TypeVisitor.visitUnknown.

Doc from javax.lang.model.type.TypeVisitor.visitUnknown.

Visits an unknown kind of type. This can occur if the language evolves and new kinds of types are added to the TypeMirror hierarchy.

Implementation Specification

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:TypeMirror

the type to visit

p:P

a visitor-specified parameter

Returns:R

a visitor-specified result

Exceptions
UnknownTypeException:
a visitor implementation may optionally throw this exception
