Class SimpleTypeVisitor6<R,P>

java.lang.Object
  javax.lang.model.util.AbstractTypeVisitor6<R,P>
      javax.lang.model.util.SimpleTypeVisitor6<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:

TypeKindVisitor6

@SupportedSourceVersion(value=RELEASE_6)
public class SimpleTypeVisitor6<R,P>
extends AbstractTypeVisitor6<R,P>

A simple visitor of types with default behavior appropriate for the RELEASE_6 source version. Visit methods corresponding to RELEASE_6 language constructs call defaultAction(javax.lang.model.type.TypeMirror, P), passing their arguments to defaultAction's corresponding parameters.

Methods in this class may be overridden subject to their general contract. Note that annotating methods in concrete subclasses with @Override will help ensure that methods are overridden as intended.

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 simple 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.

1.6

Field Detail

DEFAULT_VALUE

protected final R DEFAULT_VALUE

Default value to be returned; defaultAction returns this value unless the method is overridden.

SimpleTypeVisitor6

protected SimpleTypeVisitor6()

Constructor for concrete subclasses; uses null for the default value.

SimpleTypeVisitor6

protected SimpleTypeVisitor6(R defaultValue)

Constructor for concrete subclasses; uses the argument for the default value.

Parameters:

defaultValue - the value to assign to DEFAULT_VALUE

defaultAction

protected R defaultAction(TypeMirror e,
                          P p)

The default action for visit methods. The implementation in this class just returns DEFAULT_VALUE; subclasses will commonly override this method.

visitPrimitive

public R visitPrimitive(PrimitiveType t,
                        P p)

Visits a primitive type. This implementation calls defaultAction.

Parameters:

t - the type to visit

p - a visitor-specified parameter

Returns:

the result of defaultAction

visitNull

public R visitNull(NullType t,
                   P p)

Visits the null type. This implementation calls defaultAction.

Parameters:

t - the type to visit

p - a visitor-specified parameter

Returns:

the result of defaultAction

visitArray

public R visitArray(ArrayType t,
                    P p)

Visits an array type. This implementation calls defaultAction.

Parameters:

t - the type to visit

p - a visitor-specified parameter

Returns:

the result of defaultAction

visitDeclared

public R visitDeclared(DeclaredType t,
                       P p)

Visits a declared type. This implementation calls defaultAction.

Parameters:

t - the type to visit

p - a visitor-specified parameter

Returns:

the result of defaultAction

visitError

public R visitError(ErrorType t,
                    P p)

Visits an error type. This implementation calls defaultAction.

Parameters:

t - the type to visit

p - a visitor-specified parameter

Returns:

the result of defaultAction

visitTypeVariable

public R visitTypeVariable(TypeVariable t,
                           P p)

Visits a type variable. This implementation calls defaultAction.

Parameters:

t - the type to visit

p - a visitor-specified parameter

Returns:

the result of defaultAction

visitWildcard

public R visitWildcard(WildcardType t,
                       P p)

Visits a wildcard type. This implementation calls defaultAction.

Parameters:

t - the type to visit

p - a visitor-specified parameter

Returns:

the result of defaultAction

visitExecutable

public R visitExecutable(ExecutableType t,
                         P p)

Visits an executable type. This implementation calls defaultAction.

Parameters:

t - the type to visit

p - a visitor-specified parameter

Returns:

the result of defaultAction

visitNoType

public R visitNoType(NoType t,
                     P p)

Visits a NoType instance. This implementation calls defaultAction.

Parameters:

t - the type to visit

p - a visitor-specified parameter

Returns:

the result of defaultAction
