# 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, SimpleElementVisitor7`

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

API Note:
  Methods in this class may be overridden subject to their general contract.

  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 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 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 a new visitor is introduced, portions of this visitor class may be deprecated, including its constructors.

  1.6

## Field Details

### DEFAULT_VALUE

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

## Constructor Details

### SimpleElementVisitor6

@Deprecated(since="9") protected SimpleElementVisitor6()
Deprecated.
Release 6 is obsolete; update to a visitor for a newer release level.
Constructor for concrete subclasses; uses `null` for the default value.

### SimpleElementVisitor6

@Deprecated(since="9") protected SimpleElementVisitor6(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`

## Method Details

### defaultAction

protected R defaultAction(Element 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 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.

Implementation Requirements:
  This implementation calls `defaultAction`.
Parameters:
  `e` - the element to visit
  `p` - a visitor-specified parameter
Returns:
  a visitor-specified result

### visitType

public R visitType(TypeElement e, P p)
Visits a type element.

Implementation Requirements:
  This implementation calls `defaultAction`.
Parameters:
  `e` - the element to visit
  `p` - a visitor-specified parameter
Returns:
  a visitor-specified result

### visitVariable

public R visitVariable(VariableElement e, P p)
Visits a variable element.

Implementation Requirements:
  This implementation calls `defaultAction`, unless the element is a `RESOURCE_VARIABLE` in which case `visitUnknown` is called.
Parameters:
  `e` - the element to visit
  `p` - a visitor-specified parameter
Returns:
  a visitor-specified result

### visitExecutable

public R visitExecutable(ExecutableElement e, P p)
Visits an executable element.

Implementation Requirements:
  This implementation calls `defaultAction`.
Parameters:
  `e` - the element to visit
  `p` - a visitor-specified parameter
Returns:
  a visitor-specified result

### visitTypeParameter

public R visitTypeParameter(TypeParameterElement e, P p)
Visits a type parameter element.

Implementation Requirements:
  This implementation calls `defaultAction`.
Parameters:
  `e` - the element to visit
  `p` - a visitor-specified parameter
Returns:
  a visitor-specified result
