## javax.lang.model.util
Class SimpleElementVisitor6<R,P>

    java.lang.Object
      javax.lang.model.util.AbstractElementVisitor6<R,P>
          javax.lang.model.util.SimpleElementVisitor6<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:
  ElementVisitor<R,P>

Direct Known Subclasses:
  ElementKindVisitor6

    @SupportedSourceVersion(value=RELEASE_6)
    public class SimpleElementVisitor6<R,P>

extends AbstractElementVisitor6<R,P>

A simple visitor of program elements with default behavior appropriate for the `RELEASE_6` source version. Visit methods corresponding to `RELEASE_6` language constructs call `defaultAction(javax.lang.model.element.Element, 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 `ElementVisitor` 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 element 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:
  1.6

Field Summary
`protected R` | `DEFAULT_VALUE` Default value to be returned; `defaultAction` returns this value unless the method is overridden.

Constructor Summary
`protected` | `SimpleElementVisitor6()` Constructor for concrete subclasses; uses `null` for the default value.
`protected` | `SimpleElementVisitor6(R defaultValue)` Constructor for concrete subclasses; uses the argument for the default value.

Method Summary
`protected R` | `defaultAction(Element e, P p)` The default action for visit methods.
`R` | `visitExecutable(ExecutableElement e, P p)` Visits an executable element.
`R` | `visitPackage(PackageElement e, P p)` Visits a package element.
`R` | `visitType(TypeElement e, P p)` Visits a type element.
`R` | `visitTypeParameter(TypeParameterElement e, P p)` Visits a type parameter element.
`R` | `visitVariable(VariableElement e, P p)` Visits a variable element.

Field Detail

### DEFAULT_VALUE

    protected final R DEFAULT_VALUE

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

Constructor Detail

### SimpleElementVisitor6

    protected SimpleElementVisitor6()

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

### SimpleElementVisitor6

    protected SimpleElementVisitor6(R defaultValue)

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

  Parameters:
    `defaultValue` - the value to assign to `DEFAULT_VALUE`

Method Detail

### defaultAction

    protected R defaultAction(Element e,
                              P p)

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

  Parameters:
    `e` - the element to process
    `p` - a visitor-specified parameter
  Returns:
    `DEFAULT_VALUE` unless overridden

### visitPackage

    public R visitPackage(PackageElement e,
                          P p)

  Visits a package element. This implementation calls `defaultAction`.

  Parameters:
    `e` - the element to visit
    `p` - a visitor-specified parameter
  Returns:
    the result of `defaultAction`

### visitType

    public R visitType(TypeElement e,
                       P p)

  Visits a type element. This implementation calls `defaultAction`.

  Parameters:
    `e` - the element to visit
    `p` - a visitor-specified parameter
  Returns:
    the result of `defaultAction`

### visitVariable

    public R visitVariable(VariableElement e,
                           P p)

  Visits a variable element. This implementation calls `defaultAction`.

  Parameters:
    `e` - the element to visit
    `p` - a visitor-specified parameter
  Returns:
    the result of `defaultAction`

### visitExecutable

    public R visitExecutable(ExecutableElement e,
                             P p)

  Visits an executable element. This implementation calls `defaultAction`.

  Parameters:
    `e` - the element to visit
    `p` - a visitor-specified parameter
  Returns:
    the result of `defaultAction`

### visitTypeParameter

    public R visitTypeParameter(TypeParameterElement e,
                                P p)

  Visits a type parameter element. This implementation calls `defaultAction`.

  Parameters:
    `e` - the element to visit
    `p` - a visitor-specified parameter
  Returns:
    the result of `defaultAction`
