@SupportedSourceVersion(RELEASE_6) public class SimpleTypeVisitor6<R,P> extends AbstractTypeVisitor6<R,P>
A simple visitor of types with default behavior appropriate for theRELEASE_6source version. Visit methods corresponding toRELEASE_6language constructs calldefaultAction, passing their arguments todefaultAction's corresponding parameters. For constructs introduced inRELEASE_7and later,visitUnknownis called instead.Methods in this class may be overridden subject to their general contract. Note that annotating methods in concrete subclasses with
@Overridewill help ensure that methods are overridden as intended.WARNING: The
TypeVisitorinterface 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
visitUnknownmethod. 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.- Since:

Method Detail

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 processp- a visitor-specified parameter- Returns:
DEFAULT_VALUEunless overridden
-
visitPrimitive
public R visitPrimitive(PrimitiveType t, P p)
Visits a primitive type.- Implementation Requirements:
- This implementation calls
defaultAction. - Parameters:
t- the type to visitp- a visitor-specified parameter- Returns:
- the result of
defaultAction
-
visitNull
public R visitNull(NullType t, P p)
Visits the null type. This implementation callsdefaultAction.- Implementation Requirements:
- This implementation calls
defaultAction. - Parameters:
t- the type to visitp- 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 visitp- 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 visitp- a visitor-specified parameter- Returns:
- the result of
defaultAction
-
visitError
public R visitError(ErrorType t, P p)
Visits an error type.- Implementation Requirements:
- This implementation calls
defaultAction. - Parameters:

defaultAction
-
visitTypeVariable
public R visitTypeVariable(TypeVariable t, P p)
Visits a type variable.- Implementation Requirements:

defaultAction
-
visitWildcard
public R visitWildcard(WildcardType t, P p)
