```
public interface Element
extends javax.lang.model.AnnotatedConstruct
```
Represents a program element such as a module, package, class, or method. Each element represents a static, language-level construct (and not, for example, a runtime construct of the virtual machine).
Elements should be compared using the equals(Object) method. There is no guarantee that any particular element will always be represented by the same object.
To implement operations based on the class of an Element object, either use a visitor or use the result of the getKind() method. Using instanceof is not necessarily a reliable idiom for determining the effective class of an object in this modeling hierarchy since an implementation may choose to have a single object implement multiple Element subinterfaces.

```
javax.lang.model.type.TypeMirror asType()
```
    Returns the type defined by this element.

  - getKind
```
ElementKind getKind()
```
    Returns the kind of this element.
    
    Returns:
    
    the kind of this element
  - getModifiers
```
java.util.Set<Modifier> getModifiers()
```
    Returns the modifiers of this element, excluding annotations. Implicit modifiers, such as the public and static modifiers of interface members, are included.
    
    Returns:
    
    the modifiers of this element, or an empty set if there are none
  - getSimpleName
```
Name getSimpleName()
```
    Returns the simple (unqualified) name of this element. The name of a generic type does not include any reference to its formal type parameters. For example, the simple name of the type element java.util.Set<E> is "Set". If this element represents an unnamed package or unnamed module, an empty name is returned. If it represents a constructor, the name "<init>" is returned. If it represents a static initializer, the name "<clinit>" is returned. If it represents an anonymous class or instance initializer, an empty name is returned.
    
    Returns:
    
    the simple name of this element
    
    See Also:
    
    PackageElement.getSimpleName(), ExecutableElement.getSimpleName(), TypeElement.getSimpleName(), VariableElement.getSimpleName(), ModuleElement.getSimpleName(), RecordComponentElement.getSimpleName()
  - getEnclosingElement
```
Element getEnclosingElement()
```
    Returns the innermost element within which this element is, loosely speaking, enclosed.
    
    If this element is one whose declaration is lexically enclosed immediately within the declaration of another element, that other element is returned.
    If this is a top-level type, its package is returned.
    If this is a package, its module is returned if such a module exists. Otherwise, null is returned.
    If this is a type parameter, the generic element of the type parameter is returned.
    If this is a method or constructor parameter, the executable element which declares the parameter is returned.
    If this is a record component, the type which declares the record component is returned.
    If this is a module, null is returned.
    Returns:
    
    the enclosing element, or null if there is none
    
    See Also:
    
    Elements.getPackageOf(javax.lang.model.element.Element)
  - getEnclosedElements
```
java.util.List<? extends Element> getEnclosedElements()
```
    Returns the elements that are, loosely speaking, directly enclosed by this element. A class or interface is considered to enclose the fields, methods, constructors, record components, and member types that it directly declares. A package encloses the top-level classes and interfaces within it, but is not considered to enclose subpackages. A module encloses packages within it. Enclosed elements may include implicitly declared mandated elements. Other kinds of elements are not currently considered to enclose any elements; however, that may change as this API or the programming language evolves.
    
    Returns:
    
    the enclosed elements, or an empty list if none

  - equals
```
boolean equals(java.lang.Object obj)
```
    Returns true if the argument represents the same element as this, or false otherwise.
    
    Overrides:
    
    equals in class java.lang.Object
    
    Parameters:
    
    obj - the object to be compared with this element
    
    Returns:
    
    true if the specified object represents the same element as this

    Object.hashCode(), HashMap
  - hashCode
```
int hashCode()
```
    Obeys the general contract of Object.hashCode.
    
    Overrides:
    
    hashCode in class java.lang.Object
    
    Returns:
    
    a hash code value for this object.
    
    See Also:
    
    equals(java.lang.Object)
  - getAnnotationMirrors
```
java.util.List<? extends AnnotationMirror> getAnnotationMirrors()
```
    Returns the annotations that are directly present on this construct.
    To get inherited annotations as well, use getAllAnnotationMirrors.
    
    Specified by:
    
    getAnnotationMirrors in interface javax.lang.model.AnnotatedConstruct
    
    Returns:
    
    the annotations directly present on this construct; an empty list if there are none
    
    Since:
    
    1.6
  - getAnnotation
```
<A extends java.lang.annotation.Annotation> A getAnnotation(java.lang.Class<A> annotationType)
```
    Returns this construct's annotation of the specified type if such an annotation is present, else null.
    The annotation returned by this method could contain an element whose value is of type Class. This value cannot be returned directly: information necessary to locate and load a class (such as the class loader to use) is not available, and the class might not be loadable at all. Attempting to read a Class object by invoking the relevant method on the returned annotation will result in a MirroredTypeException, from which the corresponding TypeMirror may be extracted. Similarly, attempting to read a Class[]-valued element will result in a MirroredTypesException.
    Note: This method is unlike others in this and related interfaces. It operates on runtime reflective information — representations of annotation types currently loaded into the VM — rather than on the representations defined by and used throughout these interfaces. Consequently, calling methods on the returned annotation object can throw many of the exceptions that can be thrown when calling methods on an annotation object returned by core reflection. This method is intended for callers that are written to operate on a known, fixed set of annotation types.
    
    Specified by:
    
    getAnnotation in interface javax.lang.model.AnnotatedConstruct
    
    Type Parameters:
    
    A - the annotation type
    
    Parameters:
    
    annotationType - the Class object corresponding to the annotation type
    
    Returns:
    
    this construct's annotation for the specified annotation type if present, else null

  - accept
```
<R,P> R accept(ElementVisitor<R,P> v,
                     P p)
```
    Applies a visitor to this element.
    
    Type Parameters:
    
    R - the return type of the visitor's methods
    
    P - the type of the additional parameter to the visitor's methods
    
    Parameters:
    
    v - the visitor operating on this element
    
    p - additional parameter to the visitor
    
    Returns:
    
    a visitor-specified result
