Class AbstractTypeVisitor6<R,P>

java.lang.Object

javax.lang.model.util.AbstractTypeVisitor6<R,P>

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.

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

Modifier and Type	Method	Description
protected Object	clone()	Answers a new instance of the same class as the receiver, whose slots have been filled in with the values in the slots of the receiver.
boolean	equals(Object o)	Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison.
protected void	finalize()	Deprecated, for removal: This API element is subject to removal in a future version. May cause performance issues, deadlocks and hangs.
final Class<? extends Object>	getClass()	Answers the unique instance of java.lang.Class which represents the class of the receiver.
int	hashCode()	Answers an integer hash code for the receiver.
final void	notify()	Causes one thread which is waiting on the receiver to be made ready to run.
final void	notifyAll()	Causes all threads which are waiting on the receiver to be made ready to run.
String	toString()	Answers a string containing a concise, human-readable description of the receiver.
final void	wait()	Causes the thread which sent this message to be made not ready to run pending some change in the receiver (as indicated by notify or notifyAll).
final void	wait(long time)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.
final void	wait(long time, int frac)	Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by notify or notifyAll) or the expiration of the timeout.

Method Details

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

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

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

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

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
