# Enum Class ElementKind

java.lang.Object
java.lang.Enum<ElementKind>
javax.lang.model.element.ElementKind

All Implemented Interfaces:
  `Serializable`, `Comparable<ElementKind>`, `Constable`

public enum ElementKind extends Enum<ElementKind>
The `kind` of an element.

Note that it is possible additional element kinds will be added to accommodate new, currently unknown, language structures added to future versions of the Java programming language.
