# Class ElementKindVisitor9<R,P>

java.lang.Object
javax.lang.model.util.AbstractElementVisitor6<R,P>
javax.lang.model.util.SimpleElementVisitor6<R,P>
javax.lang.model.util.ElementKindVisitor6<R,P>
javax.lang.model.util.ElementKindVisitor7<R,P>
javax.lang.model.util.ElementKindVisitor8<R,P>
javax.lang.model.util.ElementKindVisitor9<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:
  `ElementKindVisitor14`

@SupportedSourceVersion(RELEASE_14) public class ElementKindVisitor9<R,P> extends ElementKindVisitor8<R,P>
A visitor of program elements based on their kind with default behavior appropriate for source versions `RELEASE_9` through `RELEASE_14`. For elements `Xyz` that may have more than one kind, the `visitXyz` methods in this class delegate to the `visitXyzAsKind` method corresponding to the first argument's kind. The `visitXyzAsKind` methods call `defaultAction`, passing their arguments to `defaultAction`'s corresponding parameters.

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