Class 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:
SimpleTypeVisitor7, TypeKindVisitor6 
@SupportedSourceVersion(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, passing their arguments to defaultAction's corresponding parameters. For constructs introduced in RELEASE_7 and later, visitUnknown is called instead.

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.

SimpleTypeVisitor6

@Deprecated(since="9")
protected SimpleTypeVisitor6(R defaultValue)
Deprecated.
Release 6 is obsolete; update to a visitor for a newer release level.

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

Parameters:
defaultValue - the value to assign to DEFAULT_VALUE

Methods

defaultAction

protected R defaultAction(TypeMirror e,
                          P p)

The default action for visit methods.

Implementation Requirements:
The implementation in this class just returns DEFAULT_VALUE; subclasses will commonly override this method.
Parameters:
e - the type to process
p - a visitor-specified parameter
Returns:
DEFAULT_VALUE unless overridden

visitPrimitive

public R visitPrimitive(PrimitiveType t,
                        P p)

Visits a primitive type.

Implementation Requirements:
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.

Implementation Requirements:
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.

Implementation Requirements:
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.

Implementation Requirements:
This implementation calls defaultAction.
Parameters:
t - the type to visit
p - a visitor-specified parameter
