java.lang.Object javax.lang.model.util.AbstractTypeVisitor6

All Implemented Interfaces:

TypeVisitor

Direct Known Subclasses:

SimpleTypeVisitor6

public abstract class AbstractTypeVisitor6
extends Object
implements TypeVisitor

A skeletal visitor of types with default behavior appropriate for the version 6 language level.

WARNING: The {@code 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 {@code "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 {@code "visit"}.

When such a new visit method is added, the default implementation in this class will be to call the {@link #visitUnknown 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.

AbstractTypeVisitor6

protected AbstractTypeVisitor6()

Constructor for concrete subclasses to call.

visit

public final Object visit(TypeMirror t)

Visits any type mirror as if by passing itself to that type mirror's {@link TypeMirror#accept accept} method and passing {@code null} for the additional parameter. The invocation {@code v.visit(t)} is equivalent to {@code t.accept(v, null)}.

Parameters:

t - the type to visit

Returns:

a visitor-specified result

visit

public final Object visit(TypeMirror t,
                          Object p)

Visits any type mirror as if by passing itself to that type mirror's {@link TypeMirror#accept accept} method. The invocation {@code v.visit(t, p)} is equivalent to {@code t.accept(v, p)}.

Parameters:

t - the type to visit

p - a visitor-specified parameter

Returns:

a visitor-specified result

visitUnknown

public Object visitUnknown(TypeMirror t,
                           Object p)

{@inheritDoc}

The default implementation of this method in {@code AbstractTypeVisitor6} will always throw {@code UnknownTypeException}. This behavior is not required of a subclass.

Parameters:

t - the type to visit

p

Returns:

a visitor-specified result
